Comparison between Fixation with Smooth Kirschner Wire and Cannulated Screws in Displaced Fractures of the Lateral Humeral Condyle in Children / Comparação entre fixação de fio de Kirschner liso e de parafusos canulados em fraturas deslocadas do côndilo lateral do úmero em crianças

Abstract Objective To compare the use of cannulated screws and smooth Kirschner wires in terms of reducing the presence of exuberant callus and complications in pediatric displaced fractures of the lateral humeral condyle. Methods An analytical cross-sectional study of consecutive cases was conducted from May to October 2021 with 30 children with displaced external humeral condyle fractures. The functional results regarding pain and range of motion were stratified using the Dhillon grading system. Results A total of 19 patients underwent Kirschner wire fixation, and 11 underwent cannulated screw fixation. Closed fixation was performed in 14 cases (47%), and open fixation, in 16 (53%). Of the cases included, there was no loss to follow-up. Te sample was composed of 21 (70%) male patients, and the age ranged from 5 to 15 years, with a mean of 6.96 years. The most frequent cause of fracture was fall from height (50%), which was related to greater displacement on baseline radiographs. Complications that were not related to the reduction approach or the implant used were observed in 12 (40%) cases. Conclusion The present study shows no benefits in relation to the use of smooth pins or cannulated screws to reduce the presence of exuberant callus in the consolidation of the fracture. We see that the complications that arise are related to the severity of the injury, and benefits cannot be identified in the choice of one implant over another. We could see that the Weiss classification helps to define the behavior in favor of open or closed reduction without interfering in kindness of the smooth pin or the cannulated screw for fracture fixation.

Resumo Objetivo Comparar o uso de parafusos canulados e de fios de Kirschner lisos em termos da redução da presença de calo exuberante e de complicações em fraturas pediátricas deslocadas do côndilo lateral do úmero. Métodos Um estudo analítico transversal de casos consecutivos foi realizado de maio a outubro de 2021 com 30 crianças com fraturas deslocadas de côndilo umeral externo. Os resultados funcionais para dor e amplitude de movimento foram estratificados utilizando o sistema de classificação Dhillon. Resultados Ao todo, 19 pacientes foram submetidos à fixação de fio Kirschner, e 11 à fixação de parafusos canulados. A fixação realizada foi fechada em 14 casos (47%) e aberta em 16 (53%). Dos casos incluídos, não houve perda no acompanhamento. A amostra continha 21 (70%) pacientes do sexo masculino, e a idade variou de 5 a 15 anos, com média de 6,96 anos. A causa mais frequente de fratura foi queda de altura (50%), e esteve relacionada ao maior deslocamento nas radiografias da linha de base. Complicações que não estavam relacionadas à abordagem de redução ou ao implante utilizado foram observadas em 12 (40%) casos. Conclusão Este estudo não mostra benefícios em relação ao uso de pinos lisos ou de parafusos canulados para reduzir a presença de calo exuberante na consolidação da fratura. Vemos que as complicações que surgem estão relacionadas à gravidade da lesão, e não é possível identificar benefícios na escolha de um implante ou outro. Pudemos ver que a classificação de Weiss ajuda a definir o comportamento em favor da redução aberta ou fechada sem dar preferência ao pino liso ou ao parafuso canulado para a fixação da fratura.

Does ulna fixation alter the outcome for distal-third forearm fractures in children? / A fixação da ulna altera o desfecho das fraturas do terço distal do antebraço?

ABSTRACT Introduction Fractures of the distal third of the forearm are common in the pediatric population. Conservative treatment of an ipsilateral fracture of the distal ulna metaphysis is one of the risk factors for loss of reduction. Percutaneous fixation of the fracture with K-wires is recommended. This study aims to evaluate the outcome of percutaneous fixation of both bones performed as the primary treatment. Materials and Methods A randomized, open, prospective, clinical trial was conducted, including skeletally immature patients who underwent surgery for fractures of the distal radius and ulna. They were randomized into two groups, one with fixation only of the radius fracture and the other with fixation of both the radius and the ulna fractures, and they were followed clinically and radiologically for up to 12 weeks postoperatively. Results Sixteen children were selected. In the intraoperative period, fluoroscopy was activated for a longer time when fixing the ulna (p = 0.011) and the surgical time was longer in this group (p = 0.014). In the postoperative evaluations, the group whose surgery involved the fixation of both bones had a lower postoperative pain score (p <0.001) and less time away from school (p <0.001). Conclusions In this study, postoperative pain and absence from school were both less when fixation of the radius and ulna was performed. Evidence Level II; Randomized Controlled Study.

RESUMO Introdução As fraturas do terço distal do antebraço são comuns na população pediátrica. O tratamento conservador da fratura ipsilateral da metáfise distal da ulna é um dos fatores de risco para a perda da redução. Recomenda-se a fixação percutânea da fratura com fios K. Este estudo tem como objetivo avaliar o resultado da fixação percutânea de ambos os ossos realizada como tratamento primário. Materiais e Métodos Foi realizado um estudo clínico randomizado, aberto e prospectivo, que incluiu pacientes com esqueleto imaturo que foram submetidos à cirurgia para fraturas da parte distal do rádio e a ulna. Os participantes foram randomizados em dois grupos, um com fixação apenas da fratura do rádio e outro com fixação das fraturas do rádio e da ulna, e foram acompanhados clínica e radiologicamente por até 12 semanas de pós-operatório. Resultados Dezesseis crianças foram selecionadas. No intraoperatório, a fluoroscopia foi ativada por mais tempo na fixação da ulna (p = 0,011) e o tempo cirúrgico foi maior nesse grupo (p = 0,014). Nas avaliações pós-operatórias, o grupo cuja cirurgia envolveu a fixação de ambos os ossos teve escore de dor menor depois da cirurgia (p < 0,001) e menos tempo de afastamento da escola (p < 0,001). Conclusões Neste estudo, a dor pós-operatória e o afastamento da escola foram menores quando se realizou fixação do rádio e da ulna. Nível de Evidência II; Estudo randomizado controlado.

Treatment of trochanter fractures in total hip arthroplasty with ventral compression steel wire tension band / 中华骨科杂志

Objective:To evaluate the various wire tension belt ventral compression wiring technologiesfor treating several types of femoral greater trochanter fractures in total hip replacement, according to the different types of greater trochanter of femur fractures.Methods:From March 2013 to June 2019, a total of 1 280 cases of primary total hip arthroplasty were completed in our hospital, 21 patients with greater trochanter fractures were identified in total hip replacement. There were 11 males and 10 females with an average age of 65.81±6.45 years (range 42-76 years). All of them were unilateral. There were 11 cases on the left and 10 cases on the right. There were 11 cases of osteoarthritis secondary to hip dysplasia, 4 cases of hip osteoarthritis, 4 cases of aseptic necrosis of femoral head and 2 cases of femoral neck fracture. Different wire tension belt ventral compression wiring technologies were used for each fracture type. Harris hip function score, Parker activity score, and visual analogue scale (VAS) score of hip pain were evaluated during follow-up. X-ray films were taken to evaluate the fracture healing, prosthesis position, loosening and dislocation.Results:Three new fracture types were proposed: A transverse fracture from the greater trochanter tip to the base (4 cases); B oblique fracture from the greater trochanter tip to the base (according to the fracture line direction, type B was further divided into types B1 (4 cases) and B2 (6 cases); and C fracture line from the greater trochanter to subtrochanteric plane (7 cases). Among the 21 patients, one died at an early stage, two were lost during follow-up, and 18 were followed up for an average of 30.7±7.6 months. In 18 patients, the mean operation time was 110.0±20.0 min, and the mean intraoperative blood loss was 356.9±115.7 ml. The patients' Harris score was 35.26±5.52 at the preoperative, 65.7±6.42 at the 3 months after operation, and 87.75±6.21 at the final follow-up. The difference was statistically significant ( F=377.23, P<0.001). The patients' Parker score was 2.17±0.98 at the preoperative, 5.94±1.11 at the 3 months after operation,and 8.01±0.77 at the final follow-up. The difference was statistically significant ( F=170.96, P<0.001). The patients' VAS score was 6.22±1.11 at the preoperative, 2.61±0.92 at the 3 months after operation, and 1.28±0.67 at the final follow-up. The difference was statistically significant ( F=139.71, P<0.001). Deep vein embolism, heterotopic ossification was noted in one and another patient, respectively. The patient with non-union refused reoperation and had a broken steel wire, lower-limb limp, and no notable pain at the 12-month follow-up examination. Radiographs of 17 patients showed good location of the femoral prosthesis and no chronic pain. Conclusion:Different types of greater trochanter fractures in total hip arthroplasty were proposed, using different wire tension belt ventral compression wiring technologies for the various types of femoral greater trochanter fractures during total hip replacement can improve clinical outcomes.

Application of extended trochanter osteotomy wire fixation combined with autologous bone graft in revision of total hip arthroplasty / 中国骨伤

OBJECTIVE@#To investigate the clinical effect of using lengthened trochanteric osteotomy wire fixation combined with autologous bone graft in patients undergoing revision total hip arthroplasty.@*METHODS@#From December 2010 to December 2018, 18 patients underwent revision of total hip arthroplasty with extended trochanteric osteotomy wire fixation and autogenous bone graft, including 8 males and 10 females with an average age of (78.89±3.32) years old ranging from 68 to 82 years. The time from the initial replacement to the revision was 9 to 22 (16.33±2.93) years. The patients were followed up regularly after operation. The healing time of osteotomy, the time of full weight-bearing activity, Harris score of hip joint and complications were recorded.@*RESULTS@#All 18 patients were followed up for 16 to 38 months with an average of (25.78±6.65) months. The incision length was 16 to 21 cm with an average of (18.89±1.32) cm; the operation time was 105 to 128 min with an average of (115.44±6.59) min, the bleeding volume was 240 to 285 ml with an average of (267.44±13.77) ml. The healing time of osteotomy was 12 to 18 weeks with an average of (15.61±1.75) weeks. Harris score of hip joint was (47.11±5.04) before operation, (76.39±3.85) during full weight-bearing activities, and (82.22±2.76) at the final follow-up(P<0.05). During the follow-up period, there were no complications such as limb shortening, infection, poor incision healing, prosthesis loosening and sinking, and periprosthetic fracture.@*CONCLUSION@#In revision total hip arthroplasty, the use of extended trochanteric osteotomy wire fixation combined with autologous bone graft can achieve satisfactory clinical results, but the surgeon needs to make a systematic plan for the pre-revision, intraoperative and postoperative recovery.

Comparison of two methods of fixation of supracondylar fractures of the humerus in children / Comparação de dois métodos de fixação de fraturas supracondilianas do úmero em crianças

ABSTRACT Objective: To compare the outcomes of the fixation of complete and displaced supracondylar humeral fractures in children with two different Kirschner wire configurations. Methods: The type of fixation was randomized to either crossed (19 cases), or two divergent lateral Kirschner wires (24 cases). The comparison was made six months later between the two treated groups and each group with the non-fractured elbow (clinical alignment, range of motion, Baumann angle, and lateral humeral capitellar angle). Results: 43 children were evaluated (65% boys) with a mean age of six years and five months. The carrying angle (p = 0.94), extension (p = 0.89), and the Flynn´s criteria (p = 0.56) were similar between the groups. The flexion was slightly smaller for the crossed wire group (p = 0.04), but similar to the uninjured side. The Baumann angle was not different between the two fixations (p = 0.79) and the contralateral side (p = 0.1). The lateral humeral capitellar angle was slightly greater for the lateral pinning (p = 0.08), but with no difference with the uninjured elbow (p = 0.62). No iatrogenic injuries were observed. Conclusion: Both fixations presented similar outcomes that did not significantly affect the carrying angle in relation to the non-fractured side. Level of evidence II, Therapeutic study - Investigating the results of treatment.

RESUMO Objetivo: Comparar os resultados da fixação das fraturas supracondilianas completas e desviadas do úmero de crianças com dois tipos de configuração de fios de Kirschner. Método: O tipo de fixação foi aleatorizado para fixação com dois fios de Kirchner cruzados ou laterais divergentes. Depois de seis meses foi feita a comparação entre os dois grupos fixados entre si e cada um deles com o lado não fraturado do mesmo paciente (alinhamento clínico, arco de movimento, critérios de Flynn, ângulos de Baumann e capituloumeral). Resultados: Participaram do estudo 43 crianças (65% meninos), com idade média de seis anos e cinco meses. A extensão (p = 0,89), o ângulo de carregamento (p = 0,94) e os critérios de Flynn (p = 0,56) foram semelhantes entre os dois grupos, sem ocorrência de lesões iatrogênicas. A flexão foi discretamente menor no grupo com fios cruzados (p = 0,04), mas próximo do cotovelo normal. O ângulo de Baumann não apresentou diferença entre as duas fixações (p = 0,79), bem como com o lado não fraturado (p = 0,01). O ângulo capituloumeral foi ligeiramente maior (p = 0,08) nos fios laterais, mas sem diferença em relação lado normal (p = 0,62). Conclusão: As duas fixações apresentaram resultados similares e não alteraram significativamente o ângulo frontal do cotovelo em relação ao lado não fraturado.

Treatment of irreducible femoral intertrochanteric fractures using a wire-guided device / 中华创伤杂志(英文版)

PURPOSE@#Treatment of irreducible femoral intertrochanteric fractures often requires open reduction. However, the technique unavoidably causes patients to suffer greater trauma. As such, minimally invasive techniques should be employed to reduce the surgical-related trauma on these patients and maintain a stable reduction of the fractures. Herein, a minimally invasive wire introducer was designed and used for the treatment of femoral intertrochanteric fractures. The effectiveness of using a wire-guided device to treat irreducible femoral intertrochanteric fractures was evaluated.@*METHODS@#Between 2013 and 2018, patients with femoral intertrochanteric fractures who were initially treated by intramedullary nail fixation but had difficult reduction using the traction beds were retrospectively reviewed. Decision for an additional surgery was based on the displacement of the fracture. The patients were then divided into two groups: those in the control group received an open reduction surgery while those in the observation group received a closed reduction surgery using a minimally invasive wire introducer to guide the wire that could assist in fracture reduction. The operation time, blood loss, visual analogue scale scores, angulation, reduction, neck-shaft angle, re-displacement, limb length discrepancy, and union time were then recorded and analyzed to determine the efficiency of the wire introducer technique. Categorical variables were analyzed by using Chi-square test, while continuous variables by independent t-test and the Mann-Whitney test accordingly.@*RESULTS@#There were 92 patients included in this study: 61 in the control group and 31 in the observation group. There were no significant differences in baseline demographic factors between the two groups. All surgeries were successful with no deaths within the perioperative period. The average follow-up time for the patients was 23.8 months. However, the observation group had a significantly shorter operation time, lower visual analogue scale score, less intraoperative bleeding, and shorter fracture healing time. There were no significant differences in the angulation, reduction, neck-shaft angle, and limb length discrepancy between the two groups.@*CONCLUSION@#The minimally invasive wire guide achieved a similar effect to that of open reduction in the treatment of intertrochanteric fractures with difficult reduction. Moreover, the minimally invasive wire introducer is a good technology that accurately guides the wire during reduction. Indeed, it is an effective technique and achieves good clinical outcomes in restoration of irreducible femoral intertrochanteric fractures.

Comparison of clinical efficacy of two different pin arrangements for external fixation of femoral neck fracture / 中国骨伤

OBJECTIVE@#To retrospectively analyze the clinical efficacy of external fixation in the treatment of femoral neck fracture with two different pin layout.@*METHODS@#From April 2000 to April 2018, 140 cases of femoral neck fracture were treated with closed reduction and percutaneous pin external fixation, among them 121 cases were followed up for more than 1 year, including 31 cases in traditional group, 12 males and 19 females, aged 45 to 74(65.4±8.4) years;90 cases in modified group, 39 males and 51 females, aged 12 to 75 (64.5±7.8) years. In traditional group, the first needle was put on the femoral talus, the second and third needles were put under the tension line, and the three needles were not on the same line in the lateral phase; in modified group, the first needle was drilled into the lateralcortex of the femur, obliquely penetrating the distal and proximal end of the femoral talus fracture, and the other two needles were drilled into the medial cortex of the femoral neck and the femoral talus, respectively. The operation time, hospital stay, postoperative ambulation time, femoral neck shortening rate, fracture healing time, fracture healing rate and femoral head necrosis rate of the two groups were observed and compared. Harris hip function score was used one year after operation.@*RESULTS@#These 121 patients were followed-up, the follow up time of traditional group was 13 to 45(30.5±11.4) months;the follow-up time of modified group was 14 to 120(34.5±12.5) months. There was no significant difference in operation time, hospital stay and femoral head necrosis rate between two groups (@*CONCLUSION@#Compared with the traditional group, the modified group has the advantages of lower femoral neck shortening rate, shorter fracture healing time, higher fracture healing rate and higher Harris hip function score.

A simple modification of the conventional figure-of-eight sternal closure technique

Abstract Objective: To describe a new technique of sternal closure, modified from the conventional figure-of-eight approach, which can provide a secure closure and prevent sternal complications. Methods: The modified technique is based on the intercalation of the caudal portion of each steel wire passed along the sternum. This is a retrospective analysis of patients operated with this modified technique at our institution between January 2014 and December 2016. Results: One hundred and forty-three patients underwent sternal closure with the modified technique. In-hospital mortality rate was 1.4% (n=2). No sternal instability was observed at 30 days postoperatively. Two patients developed mediastinitis that required extraction of the wires. Conclusion: Short-term results have shown that the modified sternal closure technique can be used safely and effectively, with complications rates being consistent with worldwide experience.

Kirschner Wire Migration after the Treatment of Acromioclavicular Luxation for the Contralateral Shoulder - Case Report / Migração do fio de Kirschner após o tratamento da luxação acromioclavicular para o ombro contralateral - relato de caso

Abstract The use of metal wires, called Kirschner wires, is a simple and effective fixation method for the correction of shoulder fractures and of dislocations in orthopedic surgery.Wire migration during the postoperative follow-up is a possible complication of the procedure. The authors present the case of a 48-year-old male patient, a business administrator, who suffered a fall from his own height during a soccer match resulting in right shoulder trauma. The patient was treated at a specialized orthopedics and trauma hospital and was diagnosed with a grade V acromioclavicular dislocation. Four days after the trauma, the acromioclavicular dislocation was surgically treated using ligatures with anchor wires, coracoacromial ligament transfer, and fixation with Kirshner wires from the acromion to the clavicle. At the follow-up, 12 days after the surgical procedure, migration of the Kirschner wire to the acromion edge was identified. The patient was oriented to undergo another surgery to remove the Kirshner wire, due to the possibility of further migration; nonetheless, he refused the surgery. Nine months after the surgical treatment, the patient complained of pain on the left shoulder (contralateral side), difficulty tomobilize the shoulder, ecchymosis, and protrusion. Bilateral radiographs demonstrated that the Kirschner wire, originally from the right shoulder, was on the left side. The patient then underwent a successful surgery to remove the implant.

Resumo O uso dos fios metálicos, denominados fios de Kirschner, é um método de fixação simples e eficaz para a correção de fraturas e luxações do ombro na cirurgia ortopédica. Uma das possíveis complicações é a migração do fio durante o acompanhamento pósoperatório. Os autores apresentam um caso de um paciente masculino de 48 anos, administrador, que sofreu uma queda de mesmo nível com trauma em ombro direito durante uma partida de futebol. Atendido emumhospital de referência de ortopedia e traumatologia, foi diagnosticada luxação acromioclavicular grau V. Quatro dias após o trauma, fez-se o tratamento cirúrgico da luxação acromioclavicular com amarrilhos com fios de âncora, transferência do ligamento coracoacromial e fixação com fio de Kirchner do acrômio à clavícula. No retorno, 12 dias após o procedimento cirúrgico, identificou-se amigração do fio de Kirschner do bordo do acrômio. Apesar de orientado a se submeter a cirurgia para remoção do fio, o paciente se recusou.Novemeses após o tratamento cirúrgico, o paciente apresentou dores no ombro esquerdo (lado contralateral), dificuldade para mobilizar o ombro, equimose e saliência. Foram feitas radiografias bilaterais e foi constatado que o fio de Kirschner, originalmente no ombro direito, estava no ombro contralateral. Fez-se então cirurgia para remoção do implante, com sucesso.

Modified Transosseous Wiring Technique for Neglected Fracture–Dislocation of the Proximal Interphalangeal Joint

BACKGROUND: Fracture–dislocation of the proximal interphalangeal (PIP) joint of the finger is challenging due to the high risk of stiffness. The purpose of this study is to evaluate the clinical and radiological results of a modified transosseous wiring technique for the management of chronic fracture–dislocations of the PIP joint. METHODS: Ten patients (nine men and one woman; mean age, 38.3 years; range, 21 to 69 years) with neglected fracture–dislocation of the PIP joint were included. The mean duration from injury to operation was 14.7 weeks (range, 3 to 66 weeks). The dorsolateral approach and extension block pinning were used to reduce dislocation. After thorough debridement of the scar tissues in the dorsal dead space and the fracture site, the reduction was maintained with transosseous wiring. Radiologic evaluations of bone union and arthritic changes and clinical evaluations (range of motion of the PIP joint and Disabilities of the Arm, Shoulder and Hand [DASH] score) were performed. The mean follow-up period was 12.9 months (range, 12 to 19 months). RESULTS: All patients demonstrated evidence of radiographic healing within a mean healing time of 6 weeks (range, 4 to 10 weeks); however, one had a widened gap and one had an early arthritic change. The mean range of motion in the PIP joint was 81° (range, 50° to 105°). The mean DASH score was 21.6 (range, 7.5 to 35.8). CONCLUSIONS: For chronic fracture–dislocation of the PIP joint, transosseous wiring with direct curettage and optimal bone purchase can provide satisfying outcome.

Objective To investigate the clinical effect of percutaneous hollow screw combined with tension band internal fixation for comminuted patellar fracture after arthroscopic reduction.Methods 105 patients with comminuted patellar fracture in our hospital from April 2013 to September 2017 were selected and divided into observation group (n =53) and control group (n =52) according to different treatment schemes.The control group was treated with conventional open reduction and Kirschner wire combined with tension band internal fixation,while the observation group was treated with arthroscopic assisted reduction and percutaneous cannulated screw combined with wire tension band internal fixation.The operation status and postoperative fracture healing time of the two groups were compared.One-year follow-up was performed after operation.The incidence of complications,the excellent and good rate of operation,and the preoperative and postoperative pain scores (VAS) and knee were compared.Hospital for special surgery knee score (HSS),Activity of Daily Life Scale (ADL),quality of life score (the Mos 36-item Short Form Health Survey,SF-36) were compared.Results The observation group had fewer fluoroscopy times during operation,shorter incision length and shorter healing time after operation than the control group (P ＜ 0.05);the incidence of complications in the observation group was 3.85％,lower than 20.00％ in the control group,and the excellent and good rate of operation was 96.15％,higher than 82.00％ in the control group (P ＜ 0.05);the VAS scores of the two groups were lower than those of the control group one year after operation,and the scores of HSS,ADL and SF-36 were lower than those of the control group.The preoperative improvement was higher in the observation group than in the control group (P ＜ 0.05).Conclusions Arthroscopic reduction combined with percutaneous hollow screw and tension band internal fixation for patellar comminuted fracture can reduce surgical trauma and accelerate the rehabilitation of patients.It can reduce the incidence of complications,relieve pain,improve knee function,daily living ability and quality of life,and the effect is remarkable.

Multicentre collaborative cohort study of the use of Kirschner wires for the management of supracondylar fractures in children / 中华创伤杂志(英文版)

PURPOSE@#Supracondylar fractures of the humerus cause significant morbidity in children. Nerve damage and loss of fracture reduction are common recognised complications in patients with this injury. Uncertainty surrounds the optimal Kirschner wire configuration and diameter for closed reduction and pinning of these fractures. This study describes current practice and examined the association between wire configuration or diameter and outcomes (clinical and radiological) in the operative management of paediatric supracondylar fractures.@*METHODS@#Children presenting with Gartland II or III supracondylar fractures at five hospitals in south-west England were eligible for inclusion. Collaborators scrutinised paper and electronic case notes. Outcome measures were maintenance of reduction and iatrogenic nerve injury.@*RESULTS@#Altogether 209 patients were eligible for inclusion: 15.7% had a documented neurological deficit at presentation; 3.9% who were neurologically intact at presentation sustained a new deficit caused by treatment and 13.4% experienced a clinically significant loss of reduction following fixation. Maintenance of reduction was significantly better in patients treated specifically with crossed ×3 Kirschner wire configuration compared to all other configurations. The incidence of iatrogenic nerve injury was not significantly different between groups treated with different wire configurations.@*CONCLUSION@#We present a large multicentre cohort study showing that crossed ×3 Kirschner wires are associated with better maintenance of reduction than crossed ×2 or lateral entry wires. Greater numbers would be required to properly investigate nerve injury relating to operative management of supracondylar fractures. We found significant variations in practice and compliance with the British Orthopaedic Association Standard for Trauma (BOAST) 11 guidelines.

Stainless steel wire in a figure-of-eight for repair of distal femoral physeal fractures in ten cats: a case report

Ten cats were treated for distal femoral Salter-Harris fractures types I and II using a stainless steel wire in a figure-of-eight configuration. Healing was uneventful in 8 of the cats. Early fixation failure occurred in one cat, which required revisional surgery. In one cat, lameness recurred after fracture healing, which was related to breakage of the wire. The lameness was resolved after removing the wire. At the long-term follow-up, 1 out of 6 cats was lame. This report indicates that the figure-of-eight stainless steel wire technique is an alternative method for the repair of distal femoral Salter-Harris fractures types I and II in cats.

Application of minimally invasive poking reduction technique in the treatment of thoracolumbar fractures / 中国基层医药

Objective To investigate the clinical effects of minimally invasive poking reduction technique in the treatment of single segment thoracolumbar fractures without neural impairment.Methods From February 2011 to June 2015,83 cases of thoracolumbar fractures without neural impairment underwent minimally invasive pedicle screw fixation in Linyi Central Hospital were selected and randomly divided into two groups.Group A (40 cases) was treated with poking reduction technique by percutaneous polyaxial pedical screw fixation,43 patients in group B were treated with only percutaneous polyaxial pedicle screw fixation.The perioperative index,pre-and postoperative radiography,relief of the low back pain and general health status of the two groups were recorded and compared.Results There were no statistically significant differences in the operation time,operative blood loss,hospitalization time.All patients were followed up for 20-27months (average 24 months),the scores of visual analogue scale (VAS) and Oswestry disablity index(ODI) had no statistically significant differences between the two groups in the same period(all P ＞ 0.05).Before operation,the Cobb angle,sagittal index and anterior height of the fracture vertebral body in group A were (66.3 ± 14.2) ％,(20.4 ± 6.5) °,(21.9 ± 6.6) °,respectively,which in group B were (64.8 ± 13.5) ％,(14.5 ± 7.7) °,(15.6 ± 5.9) °,respectively,the differences were not statistically significant (all P ＞ 0.05).After operation,the Cobb angle,sagittal index and anterior height of the fracture vertebral body in group A were (93.8 ± 9.8)％,(5.3 ± 3.3) °,(5.4 ± 2.0) °,respectively,which in group B were (88.0 ± 10.6) ％,(4.1 ± 2.8) °,(8.1 ± 4.7) °,respectively,the differences were statistically significant (t =8.893,2.345,3.351,all P ＜ 0.01).Conclusion The effect of poking reduction technique by percutaneous polyaxial pedical screw fixation is better than simply polyaxial pedicle screw in the treatment of thoracolumbar fracture,which is a safe and effective operation method.
