ABSTRACT

As fraturas nasais são de grande incidência dentre as fraturas faciais, podendo envolver também outras estruturas da face. O diagnóstico é baseado no exame físico, o qual muitas vezes é dificultado devido ao edema formado na região. A palpação dos contornos ósseos, verificação de presença de crepitação nasal, alterações de permeabilidade e assimetrias locais são algumas das alterações sugestivas de fraturas nasais. Além disso, a inserção do ligamento cantal medial pode ser perdida devido ao trauma ou devido ao deslocamento ósseo em que ele se encontra inserido. Exames de imagem, como radiografias e Tomografias Computadorizadas, são utilizados para a visualização das fraturas ósseas e planejamento cirúrgico. A redução aberta dos ossos nasais é indicada para fraturas de maior complexidade e cominuição, tendo em vista o adequado reposicionamento dos ossos, cartilagens e ligamentos deslocados. Assim, o objetivo deste estudo é relatar a redução aberta de uma fratura dos ossos nasais com perda de inserção do ligamento cantal medial direito, sob anestesia geral... (AU)


Nasal fractures are of great incidence among facial fractures, and may also involve other facial structures. The diagnosis is based on physical examination, which is often hampered due to the edema formed in the region. Palpation of bone contours, checking for the presence of nasal crackling, changes in permeability and local asymmetries are some of the changes suggestive of nasal fractures. In addition, the insertion of the medial canthal ligament may be lost due to trauma or due to the bone displacement in which it is inserted. Imaging exams, such as radiographs and CT scans, are used for visualizing bone fractures and surgical planning. The open reduction of the nasal bones is indicated for fractures of greater complexity and comminution, in view of the appropriate repositioning of the bones, cartilage and dislocated ligaments. Thus, the aim of this study is to report the open reduction of a fracture of the nasal bones with loss of insertion of the right medial canthal ligament, under general anestesia... (AU)

Las pruebas de imagen, como las radiografías y las tomografías computadorizadas, se utilizan para visualizar las fracturas óseas y planificar la cirugía. La reducción abierta de los huesos nasales está indicada para las fracturas de mayor complejidad y conminución, en vista del reposicionamiento adecuado de los huesos, cartílagos y ligamentos dislocados. Así, el objetivo de este estudio es relatar la reducción abierta de una fractura de los huesos nasales con pérdida de inserción del ligamento cantal medial derecho, bajo anestesia general... (AU)

ABSTRACT

Abstract Objective The aim of the present study was to analyze the clinical and radiological results of patients with type-V cystic scaphoid nonunion who were treated with percutaneous grafting and screw. Methods A total of 11 patients were treated with a percutaneous bone graft with screw fixation. The criteria for inclusion in the study were a type-V scaphoid nonunion and age > 18 years old. Those with humpback deformity, arthritis, ligament damage determined on magnetic resonance imaging, or avascular necrosis (AVN) in the nonunion fragment were excluded from the study. Results The mean follow-up time was 36 months (range: 15-53 months). At the final follow-up examination, the mean visual analogue scale score was 1.06 (range: 0-2.3). Postoperatively, the mean extension was 61.6° (44-80°), flexion 66° (60-80°), radial deviation 12° (7-20°), and ulnar deviation 25° (20-34°). The mean grip strength of the operated hand was found to be 94%, compared with the healthy side. The results obtained in the Mayo Modified Wrist Score were poor in 2 patients, good in 2 and excellent in 7 (64%). With the exception of 2 patients, union was obtained radiologically in 9 patients, with a mean of 12.6 weeks (range, 8-16 weeks). Conclusion Percutaneous grafting and screw fixation cannot replace open surgery in cases with deformity, shortening, humpbacking, or in long term nonunions; however, it is a reliable and effective treatment method in selected cases, such as Slade & Dodds type-V cystic nonunion.


Resumo Objetivo O objetivo do presente estudo foi analisar os resultados clínicos e radiológicos de pacientes com não consolidação do escafoide que foram tratados com enxerto percutâneo e parafuso. Métodos Um total de 11 pacientes foram tratados com enxerto ósseo percutâneo com fixação de parafuso. Os critérios de inclusão no estudo foram não consolidação do escafoide do tipo 5 e idade > 18 anos. Foram excluídos do estudo aqueles com deformidade corcunda, artrite, dano ligamentar determinado por ressonância magné- tica ou necrose avascular (NAV) no fragmento de não consolidação. Resultados O tempo médio de seguimento foi de 36 meses (intervalo: 15-53 meses). No exame final de seguimento, o escore médio de escala visual analógica foi de 1,06 (intervalo: 0-2,3). No pós-operatório, a extensão média foi de 61,6° (44-80°), flexão 66° (60-80°), desvio radial 12° (7--20°) e desvio ulnar 25° (20-34°). A força média de aderência da mão operada foi de 94% em comparação com o lado saudável. Os resultados obtidos no Mayo Modified Wrist Score foram ruins em 2 pacientes, bons em 2 e excelentes em 7 (64%). Com exceção de 2 pacientes, a consolidação foi confirmada radiologicamente em 9 pacientes com média de 12,6 semanas (intervalo: 8-16 semanas). Conclusão Enxerto percutâneoe fixação de parafusos não podem substituir a cirurgia aberta em casos de deformidade, encurtamento ou acorcundamento ou em não consolidação a longo prazo; no entanto, é um método de tratamento confiável e eficaz em casos selecionados, tais como a não consolidação do tipo V de Slade e Dodds.

ABSTRACT

Abstract Objective To evaluate the results obtained from the surgical treatment of malleolar ankle fractures associated with distal tibiofibular syndesmosis (DTFS) injury submitted to conventional surgical procedure for fracture fixation and DTFS fixation by suture button (SB). Methods Forty-nine patients were retrospectively evaluated, with a mean age of 45 years old and a mean follow-up of 34.1 months. Clinical and functional evaluation was based on the visual analogue scale (VAS) and on the American Foot and Ankle Society Score (AOFAS) for ankle and hindfoot, return to routine activities, and return to sport. Results The postoperative mean AOFAS and VAS were, respectively, 97.06 (confidence interval [CI 95%: 95.31-98.81] and 0.16 [CI 95% 0,04 - 0,29]. All patients returned to previous daily activities, and only 12 showed some residual symptom. There was no postoperative instability in any patient. Forty-six patients returned to sports activities and, of these, only 1 did not return to the level prior to the injury. Only two patients presented SB-related alterations. There was no report of dissatisfaction. Conclusion In malleolar fractures of the ankle with DTFS injury, the fixation of syndesmosis with SB demonstrated excellent postoperative results. Level of Evidence IV, retrospective case series.


Resumo Objetivo Avaliar os resultados obtidos do tratamento cirúrgico das fraturas maleolares do tornozelo associadas a lesão da sindesmose tibiofibular distal (STFD) submetidas a procedimento cirúrgico convencional de fixação da fratura e fixação da STFD pelo suture button (SB). Métodos Avaliou-se retrospectivamente 49 pacientes com uma média de idade de 45 anos e seguimento médio de 34,1 meses. A avaliação clínica e funcional foi baseada na escala visual analógica (EVA) e na escala American Foot and Ankle Society Score (AOFAS, na sigla em inglês) para tornozelo e retropé, retorno às atividades da rotina e retorno ao esporte. Resultados As médias pós-operatórias das escalas AOFAS e EVA foram, respectivamente, 97,06 (índice de confiança [IC 95%: 95,31 - 98,81] e 0,16 [IC 95% 0,04 - 0,29]. Todos os pacientes retornaram às atividades prévias do cotidiano, sendo que apenas 12 apresentaram algum sintoma residual. Não se verificou instabilidade pós-operatória em nenhum paciente. Ao todo, 46 pacientes retornaram às atividades desportivas e, destes, apenas 1 não retornou ao nível prévio à lesão. Apenas dois pacientes apresentaram alterações relacionadas ao SB. Não houve relato de insatisfação. Conclusão Em fraturas maleolares do tornozelo com lesão da STFD, a fixação da sindesmose com o SB demonstrou excelentes resultados pós-operatórios. Nível de Evidência IV, série de casos retrospectiva.

ABSTRACT

Abstract Objective To analyze the radiological, clinical, and functional outcomes of clavicle fractures treated with the minimally-invasive plate osteosynthesis (MIPO) technique. Methods From June 2018 to July 2019, 17 cases of clavicular fractures were managed using the MIPO technique under C-arm fluoroscopy. The functional outcomes were assessed using the Constant-Murley score and the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire. The clinical results of union, the complications, the operative time, the hospital stay, as well as infection, were analyzed. Results The mean follow-up time was of 10.41 1.75 months (range: 8 to 14 months). There were 11 male and 6 female patients, with a mean age of 39.05 10.76 years (range: 22 to 57 years). All fractures united on the mean time of 15.35 3.08 weeks (range: 12 to 20 weeks). The mean operative time was of 98.11 13.83 minutes (range: 70 to 130 minutes), and the mean length of the hospital stay was of 4.7 1.12 days (range: 3 to 7 days). The mean Constant-Murley score was of 74.82 6.36 in 4th postoperstive month, and of 92.35 5.48 in the 8th postoperative month, which was statistically significant. The mean DASH score was of 9.94 1.55 in the 4th postoperative month, and of 5.29 1.85 in the 8th postoperative month, which was also statistically significant. One patient had superficial skin infection at the site of the incision. Conclusions The MIPO technique is an alternative method for the fixation of clavicle fractures, but it is technically more demanding, and requires well-equipped operating room facilities.


Resumo Objetivo Analisar o resultado radiológico, clínico e funcional das fraturas da clavícula, tratadas pela técnica de osteossíntese com placa minimamente invasiva (MIPO). Métodos De junho de 2018 a julho de 2019, um total de 17 casos de fraturas claviculares foram tratadas com a técnica de osteossíntese com placa minimamente invasiva (MIPO), sob fluoroscopia com o braço em C. Os resultados funcionais foram avaliados por meio do escore de Constant-Murley e pelo escore de incapacidade do braço, ombro e mão (DASH). Foram analisados os resultados clínicos de consolidação, complicações, tempo cirúrgico, permanência hospitalar e infecção. Resultados O tempo médio de acompanhamento neste estudo foi de 10,41 1,75 meses (variação, 8 a 14 meses). Havia 11 pacientes do sexo masculino e seis do feminino, com média de idade de 39,05 10,76 anos (variação de 22 a 57 anos). Todas as fraturas se consolidaram no tempo médio de 15,35 3,08 semanas (variação, 12 a 20 semanas). O tempo cirúrgico médio foi de 98,11 13,83 minutos (variação, 70 a 130), sendo a permanência hospitalar média de 4,7 1,12 dias (variação de 3 a 7). O escore de Constant-Murley médio foi de 74,82 6,36 no 4° mês e 92,35 5,48 no 8° mês do pós-operatório, o que foi estatisticamente significativo. O escore DASH médio foi de 9,94 1,55 no 4° mês e 5,29 1,85 na 8ª semana do pós-operatório, também sendo estatisticamente significativo. Um paciente apresentou infecção cutânea superficial no local da incisão. Conclusões A técnica MIPO é um método alternativo para a fixação de fraturas da clavícula, porém é tecnicamente mais desafiador, já que necessita de instalações cirúrgicas mais bem equipadas.

ABSTRACT

Abstract Supracondylar humeral fracture represents ~ 3 to 15% of all fractures in children. It is the fracture that most requires surgical treatment in the pediatric population. Advances in treatment and care have contributed to a reduction in the most dramatic complication: Volkmann ischemic contracture. Nevertheless, the risks inherent to the fracture remain. Absence of palpable pulse in type-III fractures is reported in up to 20% of the cases. Careful sensory, motor, and vascular evaluation of the affected limb is crucial in determining the urgency of treatment. Older children, male patients, floating elbow, and neurovascular injury are risk factors for compartment syndrome. Medial comminution can lead to varus malunion, even in apparently innocent cases. The recommended treatment of displaced fractures is closed reduction and percutaneous pinning. Technical errors in pin placement are the main cause of loss of reduction. There is enough evidence for the addition of a third lateral or medial Kirschner wire in unstable fractures (types III and IV). Medial comminution may lead to cubitus varus even in mild displaced fractures. Based on current concepts, a flowchart for the treatment of supracondylar humeral fracture in children is suggested by the authors.


Resumo A fratura supracondiliana do úmero representa cerca de 3 a 15% de todas as fraturas na criança, sendo a que mais requer tratamento cirúrgico na população pediátrica. Apesar de os avanços no tratamento e na assistência terem contribuído para uma redução drástica da complicação mais temida, a contratura isquêmica de Volkmann, os riscos inerentes à fratura permanecem. Ausência de pulso palpável em fraturas tipo III é reportada em até 20% dos casos. Uma cuidadosa avaliação sensitiva, motora e vascular do membro acometido é fundamental na determinação da urgência do tratamento. Crianças mais velhas, sexo masculino, cotovelo flutuante, e lesão neurovascular são fatores de risco para a síndrome de compartimento. A cominuição medial pode levar à consolidação em varo, mesmo nos casos aparentemente inocentes. O método de escolha para o tratamento da fratura desviada é a redução fechada e fixação percutânea. Os erros na fixação e posicionamento inadequado dos implantes são as principais causas de perda de redução. Já existem evidências suficientes para a utilização de um terceiro fio de Kirschner, lateral ou medial, nas fraturas instáveis (tipo III e IV). Baseado nos conceitos atuais, um fluxograma para o tratamento da fratura supracondiliana do úmero na criança é sugerido pelos autores.

ABSTRACT

Objective:To investigate the prognosis of hip fracture in elderly patients with dementia.Methods:From January 2012 to December 2017, 91 dementia patients aged (82.7±6.6)y (21 males and 70 females) with hip fracture were enrolled in the study; 91 non-dementia patients matched by age, gender and fracture type were selected as controls. There were 54 cases of intertrochanteric fracture and 37 cases of femoral neck fracture. The length of hospital stay, mortality within 30 days and 1 year, walking ability and risk of reoperation were compared between the two groups. The effect of dementia on the mortality after surgery was analyzed by adjusting confounding factors through multivariate logistic regression analysis.Results:There was no significant difference in the length of hospital stay between dementia group and non-dementia group [(13.95±7.33) vs.(12.63±8.68)d, t=1.12, P=0.266]. The incidence rate of perioperative complications in dementia group was higher than that in non-dementia group [63.7%(58/91) vs. 23.1%(21/91), χ 2 = 44.59, P<0.001]. The incidence of delirium in dementia group was higher than that in non-dementia group [35.3%(42/91) vs.13.2%(12/91), χ 2 = 5.71, P=0.017]. The incidence of pulmonary infection in dementia group was higher than that in non-dementia group [11.0%(10/91) vs. 2.2%(2/91), χ 2= 11.989, P<0.001]. There was no significant difference in 30-day fatality rate [7.7%(7/91) vs. 1.1%(1/91), χ 2= 3.27, P=0.071] between two groups; while the 1-year fatality rate in dementia group was higher than that in non-dementia group [27.5%(25/91) vs. 14.3%(13/91), χ 2= 4.79, P=0.029]. After adjusting for the differences of confounding factors between the two groups, dementia was an independent risk factor for 1-year mortality after hip fracture surgery ( OR = 1.852, 95 %CI:1.048-3.043, P= 0.022). For walking ability of 1 year after operation, 22 (33.3%) patients in dementia group walked independently, 38 (57.6%) patients partially walked independently, 6 (9.1%) patients were in bed; while in non-dementia group, 45 (57.7%) patients walked independently, 27 (34.6%) patients partially walked independently, 6 (7.7%) patients were in bed; there was significant difference between the two groups (χ 2= 8.82, P=0.012). There was no significant difference in reoperation rate between two groups [6.6%(6/91) vs. 5.5%(5/91), χ2=0.10, P=0.756]. Conclusion:Compared to non-dementia patients, dementia patients with hip fracture have poorer prognosis, higher incidence of perioperative complications, pulmonary infection and delirium, higher risk of mortality 1 year after operation, and poorer ability of independent walking.

ABSTRACT

Objective:To compare the efficacy of double thread elastic locking intramedullary nail (ELIN) and threaded elastic intramedullary nail (TEIN) in the treatment of mid-shaft clavicular fracture.Methods:From August 2017 to September 2020, 33 patients with mid-shaft clavicular fractures were treated with ELIN (double threaded nail group), including 14 males and 19 females, age 52.09±16.32 years old; Robinson classification: 20 cases of type 2A2, 6 cases of type 2B1, and 7 cases of type 2B2. Thirty-two patients were selected as the control group with TEIN fixation (single threaded nail group) during the same period, including 13 males and 19 females; age 43.25±15.03 years old; Robinson classification: 19 cases of type 2A2 and 5 cases of type 2B1, 8 cases of 2B2 type. The operation time, intraoperative incision length, fracture healing time, internal fixation removal time, Constant-Murley shoulder joint score, disabilities of the arm, shoulder, and hand (DASH) score, fracture reduction and postoperative complications were compared between the two groups.Results:The patients in both groups were followed up after operation, the double-threaded screw group was followed up for 16-48 weeks (average, 23.7 weeks), and the single threaded nail group was followed up for 15-51 weeks (average, 22.9 weeks). The operation time of the double threaded nail group and the single threaded nail group were 19.45±6.74 min and 19.59±4.98 min, and the length of the incision was 1.70±0.79 cm and 1.73±0.84 cm. The fracture healing time were 12.12±1.29 weeks and 13.88±1.84 weeks. The internal fixation removal time was 13.09±1.31 weeks and 15.69±1.94 weeks. The Constant-Murley shoulder score was 93.18±3.78 points and 90.09±4.03 points, and the DASH scores were 1.49± 0.49 points and 3.85±1.13 points; There was no significant difference in operation time and incision length between the two groups ( t=0.01, 0.19; P>0.05), while fracture healing ( t=3.70, P<0.001), internal fixation removal time ( t=6.34, P<0.001), Constant-Murley shoulder score ( t=3.19, P<0.001), DASH score ( t=10.95, P<0.001) differences were statistically significant. The length of the clavicle on the healthy side was 16.38±1.09 cm in the double threaded nail group, and the length of the clavicle on the affected side after internal fixation removal was 16.33±1.12 cm. There was no obvious shortening deformity on the affected side, and there was no significant difference in the length of the clavicle between the two sides ( t=1.57, P=0.127). The clavicle lengths of the healthy side and the affected side after internal fixation removal in the single threaded nail group were 16.55±1.12 cm and 15.12±1.18 cm, and the difference was statistically significant ( t=8.02, P<0.001). The postoperative shortening values of the double-threaded screw group and the single-threaded screw group were 9.47±2.12 mm and 17.41±2.42 mm, and the difference was statistically significant ( t=14.07, P<0.001). Postoperatively, 5 cases of bursitis and 2 cases of skin irritation occurred in the double threaded nail group; While 6 cases of bursitis, 3 cases of skin irritation, 4 cases of shortening malunion, and 1 case of broken nail occurred in the single threaded nail group (fracture delayed union after replacement of internal fixation); the other patients did not experience screw retraction, wound infection, delayed fracture union or nonunion, neurovascular injury, and achieved osseous union. Conclusion:Both elastic intramedullary nails are effective surgical methods for the treatment of middle clavicle fractures, and the operation time is short and minimally invasive. However, compared with the TEIN, the fracture healing time of the double-threaded ELIN is shorter, the internal fixation removal time is earlier, the shoulder joint and upper limb function is better, and the shortening deformity is less likely to occur.

ABSTRACT

Objective:To investigate the clinical effect assistant with pelvic unlocking reduction frame for the treatment of old Denis I or II sacral fractures combined with sacral plexus nerve injury.Methods:From January 2013 to October 2020, 37 patients diagnosed with old sacral fractures with sacral plexus nerve injury which Gibbons classification was grade III were divided into the use group and the non-use group according to whether assisted with pelvic unlocking reduction frame. Eighteen patients (11 males, 7 females, mean age 38±6.4, range from 13-56) were selected into the use group and nineteen patients (14 males, 5 females, mean age 42±10.7, range 19-59) were selected into the non-use group. The three-dimensional (3D) pelvic model (1∶1) was printed before operation. The operation time, intraoperative bleeding, Matta score, visual analogue scale (VAS), Majeed score and gibbons sacral nerve injury grade of the two groups were compared. The healing time and complications of each group was recorded.Results:The average operation time of the use group and the non-use group was 121.0±16.2 min and 182.6±16.2 min, respectively, with significant difference ( t=11.54, P<0.001). The mean operative bleeding was 686±382 ml of the use group and 963±348 ml of the non-use group ( t=2.38, P=0.003). The quality of fracture reduction was evaluated according to Matta scoring standard: the excellent and good rate of the use group was 94% (17/18), and that of the non-use group was 68% (13/19) ( P=0.039). The curative effect was evaluated according to the Majeed score: the use group was 88.72±7.03 points, and that of the non-use group was 72.00±9.75 points ( t=5.96, P<0.001) at 1 year post-operative. One year after operation, the VAS scale of the use group was 0.83±0.71 points, and that of the non-use group was 1.00±0.82 points ( t=0.66, P=0.512). According to Gibbons classification, 15 patients were grade I, 1 patient was grade II and 2 patients were grade III in the use group and 11 patients were grade I, 3 patients were grade II and 5 patients were grade III in the non-use group one year after operation ( Z=-1.04, P=0.401). One patient in the use group presented rupture of plate without symptoms. In the non-use group, 1 case with internal iliac vein rupture which treated with gelatin sponge and no obvious bleeding after operation. 4 cases with unequal length of lower limbs, walking claudication. The complication rate of the use group was 6% (1/18), and that of the non-use group was 26% (5/19) ( P=0.042) . Conclusion:The lateral rectus abdominis approach combined with pelvic unlocking reduction frame can reduce the operation time and bleeding, improve the fracture reduction in the treatment of old Denis type I and II sacral fractures with sacral plexus injury.

ABSTRACT

Objective:To compare the clinical efficacy of arthroscopy-assisted and open reduction and internal fixation in the treatment of Schatzker type I-III tibial plateau fractures.Methods:The data of patients with Schatzker type I-III tibial plateau fractures who were treated from August 2017 to July 2019 were retrospectively analyzed. According to the treatment, the patients were divided into the arthroscopic-assisted minimally invasive reduction and internal fixation group (arthroscopy group) and the conventional open reduction and internal fixation group (incision group). In the arthroscopy group, there were 30 patients, 19 males and 11 females were included; the age was 45.13±7.12 years old (range, 29-60 years). Among them, 13 cases were Schatzker type I fractures, 14 cases were Schatzker type II fractures, and 3 cases were Schatzker type III fractures. In the incision group, there were 30 patients, 17 males and 13 females were included; the age was 43.53±7.79 years old (range, 31-58 years). Among them, 11 cases were Schatzker type I fractures, 15 cases were Schatzker type II fractures, and 4 cases were Schatzker type III fractures. The operation time, intraoperative blood loss, postoperative ambulation time, postoperative complete weight-bearing time and postoperative complications were recorded. The degree of knee joint swelling, knee flexion and extension range of motion and the American knee society knee score (AKS score) were compared between the arthroscopy group and the incision group.Results:Both groups were followed up. The follow-up time of the arthroscopy group were 10-18 months, with an average of 14 months; the follow-up time in the incision group were 12-18 months, with an average of 15 months. In the arthroscopy group, the operation time (87.60±9.20 min vs. 94.33±10.65 min), intraoperative blood loss (57.16±9.63 ml vs. 71.93±11.15 ml), postoperative ambulation time (5.13±1.28 d vs. 6.17±1.53 d) and postoperative complete weight-bearing time (12.83±1.68 weeks vs. 14.23±1.77 weeks) were superior to the incision group, and the differences were statistically significant ( t=2.62, 5.49, 2.83, 3.94; all P<0.05). The healing time was 13.33±1.37 weeks in the arthroscopy group and 14.86±1.63 weeks in the incision group, and the difference was statistically significant ( t=3.94, P<0.001). At 1 year after surgery, the range of flexion and extension of knee joint in the arthroscopy group was 116.77°±12.46°, which was better than that in the incision group, which was 109.13°±9.89°, and the difference was statistically significant ( t=2.63, P=0.011). The AKS score in the arthroscopy group was 164.57±11.16 points, and the score in the incision group was 149.53±14.77 points, and the difference was statistically significant ( t=4.45, P<0.001). There were no malunion or compartment syndrome in the arthroscopy group and the incision group. The total incidence of complications in the arthroscopy group was 13% (4/30), including 2 cases of poor wound healing, 2 of poor knee range of motion after operation. The total incidence of complications in the incision group was 23% (7/30), including 4 cases of poor wound healing, 1 of wound infection, 2 of poor knee range of motion after operation. And the difference between the two groups in complication incidence was not statistically significant (χ 2=1.00, P=0.317). Conclusion:Arthroscopic-assisted reduction and internal fixation in the treatment of Schatzker I-III tibial plateau fractures has the advantages of less trauma, less bleeding, early mobility, fewer complications, and better knee joint function, and there are no obvious arthroscopic-related complications, which is a safe and reliable treatment method.

According to Young-Burgess classification, 1 case of APC II, 1 case of APC III, 2 cases of LC I, 2 cases of LC III, 8 cases of VS type. The diameter of the sacroiliac screw channel, operation time, intraoperative blood loss, fracture reduction quality, pelvic asymmetry, pain visual analogue scale (VAS), Majeed score, screw placement accuracy, postoperative complications were analyzed. The pelvic asymmetry and VAS at presurgery, one week after surgery and the last follow-up were statistically analyzed.Results:There were 8 cases of robot-assisted sacroiliac screw placement and 6 cases of robot-assisted triangular fixation. All patients were followed up for 24.85±10.26 months (range, 12-51 months). The average height of S 1 sacroiliac screw channel was 14.85±3.59 mm (range, 8-22 mm). The average width was 13.78±2.64 mm (range, 9-19 mm). The average height of S 2 sacroiliac screw channel was 14.07±3.08 mm (range, 8-21 mm), and the average width was 12.64±2.84 mm (range, 7-19 mm). The operation time was 63.57±21.61 min (range, 20-120 min), and the intraoperative blood loss was 65.71±41.83 ml (range, 20-200 ml). According to Mears and Velyvis imaging evaluation criteria, 7 cases were anatomically reduced, 6 cases were satisfactory, and 1 case was unsatisfactory, and the satisfactory reduction rate was 93% (13/14). The pelvic asymmetry was 18.14±6.07 mm (range, 9-33 mm) before surgery, while one week after surgery, it was 5.43±2.44 mm (range, 3-13 mm), and it was 4.64±2.27 mm (range, 3-12 mm) in the last follow-up. One week after surgery, the last follow-up, and preoperative pelvic asymmetry was statistically different ( F=50.21, P<0.001); As for VAS for pelvic pain, the score was 6.93±1.21 points (range, 5-9 points) preoperative, 3.93±0.99 points (range, 3-6 points) one week after surgery, and 1.21±0.97 points (range, 0-3 points) at the last follow-up. There was statistical difference between 1 week after operation, the last follow-up and preoperative VAS ( F=100.89, P<0.001). The Majeed score was 86.14±7.35 points (range, 70-95 points), and the excellent and good rate was 93%(13/14). All the robot-assisted screws were located in the bone, the screw placement accuracy was 100%. No postoperative complications such as wound infection occurred, and only 1 patient complained of discomfort because of the nail tail. Conclusion:For unstable pelvic fractures in adolescents, robot-assisted pelvic posterior channel screws shows satisfactory postoperative clinical effects, which is minimally invasive, with fewer postoperative complications.

ABSTRACT

Objective:To analyze the correlation between the posterior malleolus fracture and fixation and the rotational stability of the ankle and to explore the surgical indications for posterior malleolus fracture aiming to provide the theories for the diagnosis and treatment of disorder.Methods:Twenty fresh frozen cadaver specimens were selected. Further, the extent of the tibial insertion of the posterior inferior tibiofibular ligament (PITFL) and inferior transverse tibiofibular ligament (ITTFL) complex was dissected and measured. Based on the tibial insertion of the ligament complex, the model for the supination-external rotation degree 3 ankle fracture with a posterior malleolar fragment and syndesmosis diastasis was created. Moreover, the area threshold of the posterior tibial insertion of posterior malleolus fracture was biomechanically assessed. The difference of the antirotating ability of the ankle-stiffness between simple posterior malleolus fixation and simple syndesmotic fixation was analyzed statistically.Results:The PITFL and ITTFL were presented in all specimens with relatively broad in PITFL tibial insertion. The PITFL was attached to the posterolateral tibia. The distance between the highest point of the tibial insertion and the articular line was 45.2±5.6 mm, while the ITTFL was attached to the posterior distal tibia. The distance between the highest point of the tibial insertion and the articular line was 5.5±1.0 mm. The width of the tibial insertion of the PITFL and ITTFL complex decreased as the distance from the joint line increased. Biomechanical analysis showed that the threshold of posterior area of posterior malleolus fracture was 1/4S. The stiffnesses of posterior malleolus fixation and syndesmosis stabilization were 0.264±0.080 N·m/° and 0.164 ± 0.061 N·m/°, respectively. The percentage of stiffness restored by posterior ankle fixation was 60.9%±10.2%, which was greater than that by syndesmosis stabilization 37.5%±7.9% ( t=17.09, P<0.001) . Conclusion:The surgical technique for posterior malleolus fracture should consider restoration of the axial and rotational stability of the ankle simultaneously. Posterior malleolus fracture fixation is recommended when the syndesmosis is unstable with the area ratio of posterior tibial insertion of posterior malleolus fracture greater than or equal to 1/4. Syndesmotic fixation is proposed to restore and maintain the rotational stability of the ankle when the syndesmosis is unstable with the area ratio less than 1/4. Regardless of the area ratio, the surgical indications for stable syndesmosis depend on the impact of the posterior malleolus fracture on the axial stability of tibiotalar joint, on the involved articular surface area and on the displacement degree of posterior malleolus fragment.

ABSTRACT

Objective:To compare the efficacy of posteromedial and anterolateral approach and single posteromedial reversed L approach for reduction and internal fixation in the treatment of Wahlquist type C medial tibial plateau fracture (mTPF) with coronal subluxation of knee joint.Methods:A retrospective analysis was conducted on 44 surgically treated Wahlquist type C mTPFs from January 2010 to April 2021. They were divided into single-approach group (21 cases, 12 males and 9 females with mean age of 50.71±11.28 years) and combined-approach group (23 cases, 16 males and 7 females with mean age of 51.00±10.07 years) according to their surgical approach. The single-approach group contained 14 left limbs and 7 right limbs, and there were 19 anteromedial-posteromedial-posterolateral mTPF and 2 posteromedial-posterolateral mTPF. The combined-approach group contained 18 left limbs and 5 right limbs, and there were 22 anteromedial-posteromedial-posterolateral mTPF and 1 posteromedial-posterolateral mTPF. The intraoperative blood loss and incidence of blood transferring were assessed according to the anesthetic recording. The incidence of residual knee subluxation and articular surface step, medial proximal tibial angle (MPTA) and posterior proximal tibial angle (PPTA) were measured on the postoperative plain radiograph and the function recovery of the affected knee was evaluated by the short musculoskeletal function assessment (SMFA) and the visual analogue scale (VAS).Results:The intraoperative blood loss in combined-approach group was 597.83±89.79 ml and 516.67±79.58 ml in single-approach group, there was a significant difference between the two groups ( t=3.16, P=0.003). The incidence of blood transferring was 17% (4/23) in the combined-approach group and 14% (3/21) in the single-approach group, with no significant difference (χ 2=0.08, P=0.78). All 44 patients were followed up for 8 to 133 months (mean 54 months). The rate of the residual knee subluxation and unsatisfied articular surface reduction in the combined-approach group was lower than that in the single-approach group (34.8% vs. 76.2%, χ 2=7.59, P=0.006; 30.4% vs. 61.9%, χ 2=4.39, P=0.036). There was no significant difference between the combined-approach group and single-approach groups in the postoperative MPTA (86.67°±3.31° vs. 85.86°±4.36°, t=0.88, P=0.386) and PPTA (81.57°±3.22° vs. 83.90°±6.80°, t=1.44, P=0.162). The SMFA and VAS score sin the combined-approach group were significantly better than single-approach groups (20.52±11.04 vs. 31.19±16.79; t=2.51, P=0.016; 2.74±1.32 vs. 3.76±1.04; t=3.13, P=0.007). Conclusion:The efficacy of combined posteromedial and anterolateral approach in the treatment of Wahlquist type C mTPF with coronal subluxation of knee joint is superior to that of traditional single posteromedial reversed L approach.

ABSTRACT

Objective:To investigate the application of combined distractor in the treatment of refractory distal radius fractures.Methods:From March 2018 to February 2020, the data of 32 patients with refractory distal radius fractures treated with combined distractor-assisted reduction were retrospectively analyzed. The propensity score matching method was used to establish a non-distractor group according to 1∶1 matching, with a total of 32 patients. In the distractor group, there were 15 males and 17 females, age 54.9 ±15.8 years (range, 18-77). According to AO classification, 3 cases were A3, 3 cases were B3, 16 cases were C2, 10 cases were C3. In the non-distractor group, there were 12 males and 20 females, age 59.7±14.8 years, 4 cases were A3, 5 cases were B3, 12 cases were C2 and 11 cases were C3. Main measures: surgical time, radial height, palm inclination, ulnar deviation, range of motion of the wrist, visual analogue scale (VAS), and functional assessment using disability of arm, shoulder and hand (DASH) and modified Mayo wrist score (MMWS).Results:A total of 64 patients were included in this study, and all patients successfully completed the operation and were followed up for 12-54 months, with an average of 17.8 months. The operative time of the distractor group was 91.2±14.6 min, which was significantly lower than that of the non-distractor group 137.6±27.3 min, and the difference was statistically significant ( t=8.48, P<0.001); the radial height in the distractor group 11.5±1.4 mm was significantly higher than that in the non-distractor group 10.6±1.3 mm, and the difference was statistically significant ( t=2.59, P=0.012). At the last follow-up, there were no statistically significant differences in the palm inclination 7.9°±4.4° vs. 7.5°±3.5°, ulnar deviation 23.3°±5.7° vs. 22.3°±4.5°, wrist flexion 63.2°±15.3° vs. 62.6°±11.1°, dorsiflexion 63.5°±10.7° vs. 62.4°±15.2°, pronation 69.2°±11.8° vs. 67.0°±11.0°, supination 73.1°±10.4° vs. 72.0°±8.7°, VAS 0.8±0.5 points vs. 0.9±0.7 points, DASH score 12.9±6.6 points vs. 13.4±7.0 points amd MMWS 84.1±5.8 points vs. 83.5±6.2 points ( P>0.05). One patient in the distractor group had symptoms of extensor muscle irritation, and the symptoms disappeared after the internal fixation was removed; 2 patients in the non-spreader group developed carpal tunnel syndrome, which improved after incision and decompression treatment. Conclusion:For refractory distal radius fractures, the use of combined distractor can achieve better radius height recovery and shorten the operation time, and has a satisfactory postoperative effect.

ABSTRACT

Objective:To investigate the efficacy of dual plate fixation in the treatment of proximal humeral fracture with comminuted calcar.Methods:From July 2018 to April 2020, 25 patients (7 males and 18 females) were treated operatively for proximal humeral fractures with calcar comminution using anterior plate and lateral Philos plate. The data of patients who were followed up for more than 12 months was retrospectively analyzed. The mean age was 58.3 years (range 33-79 years). There were 13 right sides (all principal sides) and 12 left sides (all non-principal sides). The causes of injuries included: falling on flat ground (12 cases), traffic accidents (11 cases) and falling from height (2 cases). According to Neer classification, there were 7 cases of two-part fractures, 16 cases of three-part fractures and 2 cases of four-part fractures. A number of parameters including patient demographics, mechanism of injury, operative time, time to union, the range of shoulder motion, visual analogue scale (VAS), American Shoulder and Elbow Surgeons (ASES) score, Constant-Murley shoulder joint score, neck-shaft angle and the complications were recorded.Results:All of 25 patients were operated and followed up for 24.7 months (range 14 to 36 months). The operation time was 124.3 min (75-185 min), and the blood loss was 178.4 ml (100-350 ml). All patients had healed fractures at the last follow-up, and the neck-shaft angle was 132.88°±8.11° immediately after surgery, and 132.68°±8.36° at the last follow-up. All 25 patients healed completely in 4.7 months (range 3-5 months). Range of shoulder joint motion were forward flexion 161.20°±13.01° (range 140°-180°), external rotation 37.60°±7.65° (range 20°-45°), and internal rotation T 4-L 4 levels. VAS score was 0.36±0.81 points (range 0-3 points), while ASES score was 87.32±8.78 points (range 57.7-100 points) and Constant-Murley score was 89.40±8.37 points (range 60 to 100 points). Overall satisfaction score (Constant-Murley score) was excellent in 23 cases, and good in 2 cases. No obvious complications occurred. Conclusion:The combination of anterior plate and lateral Philos plate in the treatment of proximal humerus fractures with comminuted calcar can achieve stable fixation and satisfactory postoperative results.

ABSTRACT

Objective:To explore the clinical effects of combined medial and lateral approaches in treating of calcaneal fractures combined with sustentaculum tali fractures and/or dislocations of sustentaculum tali-talus joint.Methods:Four adult cadaver specimens (8 feet) were selected, of which two (4 feet) were dissected on the medial side of the calcaneus to observe the adjacency and exposure range of sustentaculum tali. The other two specimens were simulated as medial and lateral approaches to reduce and fix calcaneal fractures. Retrospective analysis of 9 cases (9 feet) of Sanders II-IV type calcaneal fractures with combined medial and lateral approaches in the treatment of fractures and/or dislocations of sustentaculum tali-talus joint was performed. The average age was 49.9±11.3 (25-58) years. During the operation, the medial incision was made first, and the sustentaculum tali fracture was temporarily reduced and fixed to the talus. Then the lateral incision was made to expose the lateral side of the calcaneus, and the fracture fragments were reduced and fixed; the sustentaculum tali was fixed laterally with screws, and 2 cases were additionally fixed medially with absorbable rods. At the same time, six cases (8 feet) of calcaneal fractures with sustentaculum tali fractures and/or dislocations of sustentaculum tali-talus were treated with lateral approach as a control group. The lateral sides of both groups were fixed with calcaneal locking plate and implanted with demineralized bone matrix into the cavity after articular surface reduction. The B?hler and Gissane angles of the two groups of patients were measured at 1 year after operation. The American Orthopaedic Foot and Ankle Society (AOFAS) scoring system was used to evaluate the clinical efficacy.Results:The sustentaculum tali-talus joint had a shape of an inverted "V" with two divided parts. The tip of the sustentaculum tali was exposed through the front window of the posterior tibial tendon. The sustentaculum tali and the medial side of the calcaneal body was completely exposed and fixed through the window between the posterior tibial tendon and the flexor digitorum longus tendon. The postoperative incision blood loss in the combined medial and lateral approach group was 73.6±4.3 ml, which was greater than that in the lateral approach group (70.6±7.1 ml) ( t=2.18, P=0.045). The lateral incision healed in both groups. The medial incision healed delayed in 1 patient in the combined medial and lateral approach group. The fractures in the combined medial-lateral approach group and the lateral approach group were both healed. The healing duration was 12.2±2.1 weeks and 12.8±2.8 weeks, respectively, without significant difference ( t=0.50, P=0.622). The B?hler angles of the combined medial-lateral approach group and the lateral approach group were 37.0°±5.7° and 27.9°±4.0° at 1 year after operation, respectively. These values were greater than the preoperative values of 4.7°±3.4° and 3.9°±2.9° ( P<0.05), with significant difference between groups ( t=3.76, P=0.002). The Gissane angles were 133.2°±9.8° and 139.1°±9.4° respectively, which were lower than those of 172°±7.3° and 175.6°±5.6° before operation ( P<0.05). There was no significant difference between the groups ( t=1.26, P=0.226). The AOFAS score of the combined medial and lateral approach group was 93.6±4.0 points, which was higher than that of the lateral approach group (84.3±8.2 points) ( t=3.03, P=0.008). Conclusion:Intra-articular calcaneal fractures combined with a high probability of sustentaculum tali fractures and/or dislocations of sustentaculum tali-talus joint. Compared with the simple lateral approach, the use of the combined medial-lateral approach and the medial-lateral surgical sequence is beneficial to restore the calcaneal alignment and anatomic shape, especially the alignment relationship of the medial calcaneus and talus, so as to obstain better early clinical outcomes.

ABSTRACT

Objective:To investigate the efficacy of elastic locking intramedullary nail (ELIN) in the treatment of mid clavicle fractures.Methods:From January 2014 to December 2020, the data of 61 patients with mid-clavicle fracture treated with ELIN were retrospectively analyzed. Among them, 38 patients were from the Fourth Central Hospital Affiliated to Nankai University and 23 were from the Second People's Hospital of Hulunbuir City. There were 36 males and 25 females, aged from 19 to 85 years (average, 54.5 years), 39 cases on the left side and 22 cases on the right side. According to Robinson's classification, there were 20 cases of type 2A2, 29 cases of type 2B1 and 12 cases of type 2B2. There was no nerve or vascular injury before operation. The postoperative evaluation measures included incision length, operation time, blood loss, fracture reduction, fracture healing time, ELIN removal time, shoulder Constant-Murley score, disabilities of the arm, shoulder, and hand (DASH) score, and related complications.Results:All patients were followed up for 13-51 weeks (average, 21.8 weeks). There were 34 cases of closed reduction and 27 cases of mini-open reduction, and the length of incision was 2.04±1.08 cm. The closed reduction operation time was 20.32±7.11 min, and the mini-open reduction operation time was 20.30±5.37 min. The intraoperative blood loss was 6.47±2.31 ml in the closed reduction group and 27.41±11.55 ml in the mini-open reduction group. Compared with the healthy side, the clavicle length of the affected side was shortened by 7.74%±3.51% of pre-operation and 0.71%±1.00% of post-operation, there was statistically significant difference in the length of clavicle shortening of pre- and post-operation ( t=3.84, P<0.001). The fracture healing time was 10.48±2.39 weeks. The removal time of ELIN was 13.39±2.69 weeks. At the last follow-up, the Constant-Murley score of shoulder joint was 98.87±1.74. The average of DASH score was 1.13 (range, 0-10). There were 18 cases of skin irritation after operation, of which 13 cases formed pressure sores at the tail end 3-6 weeks after the operation, and were treated with dressing change and keeping clean; 4 cases of skin irritation at the tail end formed bursitis, which disappeared after removal of the internal fixation. In 1 case, the tip of ELIN penetrated the anterior cortex from the proximal clavicle and stimulated the skin. Radiograms showed continuous callus at 4 weeks after operation, and there was no local tenderness on the physical examination, which reached the clinical healing standard, and the symptoms were relieved after the nail was removed. No serious complications such as neural and vascular injury, nail breaking, delayed healing, infection, numbness or discomfort in the subclavian area occurred in all cases, and all patients were satisfied or basically satisfied with the aesthetic of the skin appearance. Conclusion:Minimally invasive and microstress shielding fixation of mid-clavicle fracture with ELIN have the advantages of simple operation, minimally invasive, beautiful appearance, anti-short-shrinkage and rapid fracture healing etc. It is an effective surgical method for the treatment of mid-clavicle fractures.

ABSTRACT

Objective:To compare the clinical effects of bridge combined internal fixation system and locking plate system in treating closed humeral shaft fracture.Methods:From August 2017 to August 2020, there were 45 patients with closed humeral shaft fracture treated with surgery. Bridge combined internal fixation system were performed in 19 patients (bridge combined group, aged 38.3±11.9, range 21-72 years), including 13 males and 6 females. Further, there were 26 patients underwent locking plate system (locking plate group, aged 41.2±14.7, range 20-79 years), including 20 males and 6 females. The operation was performed by minimal invasive percutaneous osteosynthesis with fixators. The patients were followed up every 4 weeks. The fracture healing condition was recorded. Shoulder function was assessed according to University of California at Los Angeles (UCLA) shoulder rating scale and elbow function was assessed according to Mayo elbow performance score (MEPS).Results:The follow-up duration of all patients were 14.2±4.7 (range 10-32) months. All wound were healed completely. The operation duration in bridge combined group (68.1±12.5 min) was longer than that in locking plate group (56.3±11.6 min) ( t=3.32, P=0.002). The blood loss of bridge combined group and locking plate group were 112.6±20.2 ml and 104.2±14.1 ml, respectively ( t=1.65, P=0.107). The volume of drainage of bridge combined group was 68.4±16.2 ml and that of locking plate group was 73.1±14.9 ml ( t=1.00, P=0.323). The hospitalization time of bridge combined group was 9.7±2.3 d and the locking plate group was 9.4±1.9 d ( t=0.57, P=0.573). All above parameters had no statistical significance between the two groups. Fracture nonunion occurred in 1 of 19 patients in bridge combined group. The fracture healing time was 15.3±4.3 weeks in another 18 cases, while that of locking plate group was 15.9±3.9 weeks ( t=0.47, P=0.638). At 4-weeks postoperative follow-up, the UCLA shoulder score (18.1±3.9) and the MEPS (55.4±6.8) of bridge combined group were lower than those of locking plate group ( P<0.05). At 8-weeks postoperative follow-up, the shoulder score (26.2±4.3) and the MEPS (70.9±6.5) of bridge combined group were lower than those of locking plate group ( P<0.05). At 12-weeks postoperative follow-up, the UCLA shoulder score (33.6±1.0) and the MEPS (91.0±3.7) of bridge combined group had no statistical difference with those of locking plate group ( P>0.05). Conclusion:The bridge combined internal fixation system could provide personalized and multidimensional fixation according to the fracture type. The clinical effects of bridge combined internal fixation system on humeral shaft fracture are similar to the locking plate system at 12 weeks postoperatively. However, the operation duration of bridge combined system is longer and with increased the risk of nonunion.

ABSTRACT

Objective:To investigate the importance of measuring and restoring distal radius tear drop angle in the treatment of distal radius middle column fracture with anterior collapse of lunate fossa joint.Methods:Thirty one cases of distal radius fractures in 29 patients was reported for 2 years from January 2018 to January 2020. Two patients with both distal radius fractures were included in this study. All cases in this group were treated by operation. Among the 29 patients, there were 20 males and 9 females. Their ages were 44.9±15.1 years (ranged from 20 to 78 years). Two patients with both distal radius fractures were included in this study, due to both teardrop angle (TDA) reduced. The time from injury to operation was 4-17 d, with an average of 6.9 d. Except for 2 cases of fracture with simple volar approach, the other cases were treated with combined volar and dorsal approach. All patients were treated with open reduction and internal fixation with plates and bone grafting. The teardrop angle was measured before and after operation, and the effect of surgical recovery of teardrop angle was compared. The wrist function was evaluated by Gartland-Werley scores.Results:The wounds of all patients healed in one stage without postoperative infection. The follow-up time of 29 patients were 15.1±5.2 months, ranged from 7 to 31 months. The healing time for all fractures was 10.3±2.9 weeks (from 8 to 16 weeks). No fracture nonunion or redisplacement. In 31 cases, the tear drop angle was 33.4°±5.83° (20°-45°) before operation, and 58.9°±9.89° (35°-70°) after operation. At the end of follow-up, Gartland-Werley scores was 4.7±4.6, ranged from 0 to 17. Among them, 10 cases were excellent, 16 were good, 5 cases were fair, and the excellent and good rate was 83.9%. The Gartland-Werley scores of the two subgroups with postoperative tear drop angle recovery ≥50° and <50° were compared, and the results were significantly different (the excellent and good rate for two subgroups were 96.2% and 20.0% respectively ( P=0.001). Conclusion:The distal radius fracture with significantly reduced tear drop angle should be actively treated. The measurement and recovery of tear drop angle is an important factor affecting the functional outcome of distal radius fracture with anterior edge collapse of lunate fossa joint, which should be highly concerned by clinical doctors. The recovery of teardrop angle mostly requires dorsal approach.

ABSTRACT

Objective:To investigate the clinical effect and safety of reduction and fixation for the anterior glenoid fracture through an axillary approach.Methods:Two autopsy specimens (a total of 4 shoulder joints) were used to simulate the surgery of open reduction and internal fixation to treat anterior glenoid fracture through an axillary approach. Specimens were placed in the lateral decubitus position. An incision was made in the posterior axillary line to expose the lateral side of the scapula through the interval ahead of the latissimus dorsi muscle. Attended to the separation and protection of the axillary nerve, posterior humerus artery, thoracic dorsal nerve, and scapular artery. The surgical area of the axillary approach was divided into the upper "quadrilateral area" and the lower "trilateral area", which exposed the anteroinferior glenoid, neck, and the full length of lateral border of the scapula. Thirteen cases (7 males and 6 females) were involved in this study, all patients were diagnosed with anterior glenoid fracture and treated by open reduction and internal fixation through the axillary approach between April 2018 and December 2020. Constant-Murley score and Disabilities of the Arm, Shoulder and Hand (DASH) were used to evaluate the clinical efficacy.Results:Thirteen patients were enrolled for final analysis, which included 12 right cases and 1 left case. The average age was 50.38±13.74 years (range 24-67 years). All 13 patients were classified as Ideberg type Ia fracture. Anatomical buttress plates were used in 5 cases, cannulated screws combined with metacarpal plates in 7 cases, and distal radius plate in 1 case. The average length of follow-up was 13.00±5.97 months (range 6-26 months). No delayed union or malunion in all cases at the last follow-up visits. The average of Constant-Murley score was 62.46±10.26 points (range 45-83) and the DASH score was 27.56±9.76 points (range 14.14-43.33) at the three months follow up visits. At 6 months postoperatively, the Constant-Murley score was 80.85±8.32 points (range 65 to 90) and the DASH score was 11.47±8.56 points (range 0 to 35.00). Constant-Murley score at the final patient's follow-up visit was 84.54±8.95 points (range 70-95), and the DASH score was 10.94±8.67 points (range 1.67 to 33.33 points). The joint function gradually recovered with time. The functional scores at 3 months, 6 months after surgery, and final follow-up visit had significant differences ( P<0.05). Conclusion:The axillary approach is a safe and feasible approach for the treatment of the anterior glenoid fracture. This approach exposes the anteroinferior glenoid and the lateral border of the scapula, which reduces rotator-cuff injury and achieves anatomic reduction and strong fixation of the fracture. The axillary approach surgery also allows early functional physiotherapy after surgery.
