ABSTRACT

OBJECTIVE@#To compare the biomechanical stability of three cross-bridge headless compression screws and locking plates in the fixation of Mason type Ⅲ radial head fractures by finite element method.@*METHODS@#Using reverse modeling technology, the radial CT data and internal fixation data of a healthy 25-year-old male were imported into the relevant software. Three-dimensional finite element model of 3 cross-bridge headless compression screws and locking plates for MasonⅢ radial head fractures were established, and the radial head was loaded with 100 N axial loading. The maximum displacement, maximum Von Mises stress and stress distribution of the two groups were compared.@*RESULTS@#The maximum displacements of the three cross-bridge screws group and locking plate group were 0.069 mm and 0.087 mm respectively, and the Von Mises stress peaks were 18.59 MPa and 31.85 MPa respectively. The stress distribution of the three screws group was more uniform.@*CONCLUSION@#Both internal fixation methods can provide good fixation effect. CoMPared with the locking plate fixation method, the 3 cross-bridge headless compression screws fixation is more stable and the stress distribution is more uniform.

ABSTRACT

OBJECTIVE@#To review the advancement made in the understanding of valgus impacted proximal humeral fracture (PHF).@*METHODS@#The domestic and foreign literature about the valgus impacted PHF was extensively reviewed and the definition, classification, pathological features, and treatment of valgus impacted PHFs were summarized.@*RESULTS@#PHF with a neck shaft angle ≥160° is recognized as a valgus impacted PHF characterized by the preservation of the medial epiphyseal region of the humeral head, which contributes to maintenance of the medial periosteum's integrity after fracture and reduces the occurrence of avascular necrosis. Therefore, the valgus impacted PHF has a better prognosis when compared to other complex PHFs. The Neer classification designates it as a three- or four-part fracture, while the AO/Association for the Study of Internal Fixation (AO/ASIF) categorizes it as type C (C1.1). In the management of the valgus impacted PHF, the selection between conservative and surgical approaches is contingent upon the patient's age and the extent of fracture displacement. While conservative treatment offers the advantage of being non-invasive, it is accompanied by limitations such as the inability to achieve anatomical reduction and the potential for multiple complications. Surgical treatment includes open reduction combined with steel wire or locking plate and/or non-absorbable suture, transosseous suture technology, and shoulder replacement. Surgeons must adopt personalized treatment strategies for each patient with a valgus impacted PHF. Minimally invasive surgery helps to preserve blood supply to the humeral head, mitigate the likelihood of avascular necrosis, and reduce postoperative complications of bone and soft tissue. For elderly patients with severe comminuted and displaced fractures, osteoporosis, and unsuitable internal fixation, shoulder joint replacement is the best treatment option.@*CONCLUSION@#Currently, there has been some advancement in the classification, vascular supply, and management of valgus impacted PHF. Nevertheless, further research is imperative to assess the clinical safety, biomechanical stability, and indication of minimally invasive technology.

ABSTRACT

OBJECTIVE@#According to the characteristics of spinal burst fractures in high-altitude areas and the local medical conditions, to explore the clinical efficacy of short-segment fixation with pedicle screws combined with screw placement in injured vertebrae in the treatment of thoracolumbar burst fractures.@*METHODS@#From August 2018 to December 2021, 12 patients with single-vertebral thoracolumbar burst fractures without neurological symptoms were treated with injured vertebral screw placement technique, including 7 males and 5 females;aged 29 to 54 years old, with an average of(42.50±7.95) years old;6 cases of traffic accident injury, 4 cases of high fall injury, 2 cases of heavy object injury;2 cases of T11, 4 cases of T12, 3 cases of L1, 2 cases of L2, and 1 case of L3. In the operation, screws were first placed in the upper and lower vertebrae of the fracture, pedicle screws were placed in the injured vertebra, and connecting rods were installed, and the fractured vertebral body was reset by positioning and distraction. Visual analogue scale (VAS) and Japanese Orthopedic Association (JOA) scoring were used to evaluate the changes in pain and quality of life of patients, and the kyphotic correction rate and correction loss rate of the injured segment were measured by X-ray.@*RESULTS@#All operations were successful without significant intraoperative complications. All 12 patients were followed up, the duration ranged from 9 to 27 months, with an mean of (17.75±5.79) months. VAS at 3 days after operation was significantly higher than that at admission (t=6.701, P=0.000). There was significant difference in JOA score between 9 months after operation and at admission (t=5.085, P=0.000). Three days after operation, Cobb angle was (4.42±1.16)°, and the correction rate was (82±5)% compared with (25.67±5.71)° at admission. Cobb angle was (5.08±1.24) °at 9 months after operation, with a corrected loss rate of (16±13)%. No loosening or breakage of internal fixation was found.@*CONCLUSION@#Under the high-altitude hypobaric and hypoxic environment, the effect of the operation should be ensured while reducing the trauma. The application of the technique of placing screws on the injured vertebra can effectively restore and maintain the height of the injured vertebra, with less bleeding and shorter fixed segments, which is an effective method.

ABSTRACT

OBJECTIVE@#To retrospectively assess the advantages of the modified Uhl technique in the treatment of Colles' fracture guided by the principles of Chinese osteosynthesis (CO) concept.@*METHODS@#A retrospective study was conducted on 358 patients with Colles' fracture treated with the modified Uhl technique of closed reduction and percutaneous pin between January 2016 and June 2021. Out of these, 120 eligible cases were selected and categorized into two groups according to different surgical methods:the closed reduction and percutaneous pin group, and the open reduction group. Sixty-eight patients in the closed reduction and percutaneous pin group were treated with the modified Uhl technique, while fifty-two patients in the open reduction group were treated with open reduction and internal fixation using plates. The modified Sarmiento imaging score, Gartland-Werley wrist score, operation time, hospital stay, and treatment costs between the two groups were compared at a 6-month postoperative follow-up.@*RESULTS@#There were no significant differences in terms of gender, age, affected side, injure factors, time of injury to surgery, Sarmiento imaging score, and Gartland-Werley wrist joint score (P>0.05). The closed reduction and percutaneous pin group exhibited an operation time of (35.88±14.11) minutes, hospitalization stay of (9.78±2.48) days, and treatment costs of (16 074.91±1 964.48) yuan, while the open reduction group demonstrated comparatively longer operation time of (65.48±14.26) minutes, hospitalization stay of (15.88±2.00) days, and treatment costs of (20 451.27±1 760.22) yuan (P<0.01).@*CONCLUSION@#The modified Uhl technique presents notable advantages in the management of Colles' fracture, including reliable fixation, less trauma, shorter operation time, less pain, shorter hospital stay, and cost-effectiveness. This technique exhibits promising potential for broader clinical application. However, it is important to note that the pin could potentially damage tendons, and in cases of Colles' fractures with osteoporosis and comminuted fragments, additional techniques may be required for reliable fixation.

ABSTRACT

OBJECTIVE@#To investigate the clinical effect of double pulley combined with suture bridge in the treatment of comminuted fracture of the lower pole of the patella.@*METHODS@#From January 2018 to June 2020, 15 patients with comminuted fracture of the lower pole of the patella were treated with double pulley and suture bridge technology, including 9 males and 6 females, aged 28 to 68 years old with an average of (42.4±9.6) years old. All patients had obvious knee joint pain and limited movement after injury. All knee joints were examined by X-ray and CT, which confirmed that they were all comminuted fractures at the lower level of the patella. After operation, X-ray films of the knee joint were taken regularly to understand the fracture healing, the Insall Salvati index was measure, the range of motion of the joint was recorded, and the function of the knee joint was evaluateed by the Bostman scoring system.@*RESULTS@#All the 15 patients were followed up for 7 to 24 months with an average of (11.4±4.2) months, and there was no obvious anterior knee pain. At the last follow-up, the knee joint range of motion of the affected limb was 105° to 140° with an average of (128.5±12.8) °, and the Insall Salvati index was 0.79 to 1.12 with an average of (0.92±0.18). The X-ray film showed that the patella was bone healing, and no anchor fell off, broken, or displaced fracture block was found. Bostman patellar fracture function score was 27.85±2.06, 13 cases were excellent, 2 cases were good.@*CONCLUSION@#Double pulley technique combined with suture bridge technique is reliable for reduction and fixation of comminuted fracture of the lower pole of patella, and patients can start functional exercise early after operation.

DISCUSIÓN El uso de placas malla permite el manejo de fracturas conminutas de patela preservando stock óseo y restaurando la indemnidad del aparato extensor, con una osteosíntesis estable y poco prominente. Casos en que antiguamente la única alternativa era la patelectomía parcial y reinserción del tendón patelar ahora tienen etas placas como opción de manejo. CONCLUSIÓN El uso de placas malla en fracturas conminutas de patela es una alternativa atractiva por la estabilidad que brindan, la capacidad de reservar stock óseo, y la baja tasa de reintervenciones


OBJETIVE To describe the surgical technique for the use of a mesh plate in a case of comminuted patellar fracture and the mid-term follow up outcomes. MATERIALS AND METHODS We present a case of comminuted patella fracture managed with the use of a mesh plate and an associated cannulated screw, thus avoiding partial patellectomy and its possible complications. RESULTS Four months postoperatively, the patient presented full knee range of motion and could be discharged to return to work, with no complications or reinterventions. DISCUSSION The use of mesh plates enables the management of comminuted patellar fractures preserving bone stock and restoring the extensor mechanism with a stable and little prominent osteosynthesis. Cases which previously would only have been treated by partial patellectomy and patellar tendon reinsertion can be treated with these plates. CONCLUSION The use of mesh plates for comminuted patellar fractures is an attractive option due to their stability, their ability to preserve bone stock, and the low rates of reintervention.

ABSTRACT

OBJECTIVE@#To explore the clinical efficacy of external micro-locking plate combined with closed reduction in the treatment of fifth metatarsal comminuted fracture with severe soft tissue injury.@*METHODS@#From January 2018 to December 2019, 13 patients received micro-locking plate combined with closed reduction treatment due to the fifth metatarsal comminuted fracture with severe soft tissue injury. There were 11 males and 2 females patients, ranging in age from 21 to 69 years. According to the fracture AO fracture classification, 9 cases belonged to type 87(S)-C2.2 and 4 cases belonged to type 87(S)-C2.1. The fifth metatarsal cuneiform articular surface was not involved, and all of them were comminuted fractures of the fifth metatarsal shaft. All soft tissues were damaged to varying degrees. Three patients got small defect of skin and soft tissue, and they were treated with debridement and suture after one-stage emergency surgery. The fracture healing and complications were observed, and the clinical efficacy was evaluated according to the midfoot function score of American Orthopaedic Foot & Ankle Society (AOFAS) at the latest follow-up.@*RESULTS@#All patients were followed up, and the duration ranged from 3 to 12 months. One patient had delayed union. One patient had local skin necrosis and was treated with second-stage skin grafting to repair the wound surface. No external screw breakage or infection was reported, the skin soft tissue healed satisfactorily and reached bony union, with the union time ranging from 8 to 19 weeks. The postoperative functional recovery was rated according to the midfoot score of AOFAS, the score ranged from 49 to 98, and 7 patients got an excellent result, 4 good, 1 fair and 1 poor.@*CONCLUSION@#The external micro-locking plate combined with closed reduction in the treatment of fifth metatarsal comminuted fracture with severe soft tissue injury has the advantages of simple operation, good stability and low infection rate, which is helpful to the repair of soft issue injury, and the fixation can be removed early in outpatient clinic. To sum up, this surgical procedure is suitable for patients with severe soft tissue injury and comminuted fracture to avoid periosteum stripping. The space occupying is smaller than the micro-external fixator, which is convenient for patients with early functional exercise.

ABSTRACT

OBJECTIVE@#To explore the clinical application of lockedge suspension combined with three steel wires vertical fixation in comminuted fracture of inferior pole of patella.@*METHODS@#From August 2016 to May 2019, 23 patients with comminuted fracture of the lower pole of the patella, including 14 males and 9 females, were treated with lockedge suspension combined with three steel wires vertical fixation. The age ranged from 34 to 68 (55.0±1.2) years. One year after operation, the pain and function were evaluated by pain visual analogue scale(VAS) and knee flexion and extension range of motion, and the clinical efficacy was evaluated by Lysholm knee score standard.@*RESULTS@#All 23 patients were followed up for 12 to 14, with a mean of(13.0±0.5) months. One patient had skin irritation by the tail of the steel wire, and the rest had no postoperative complications such as incision infection, internal fixation loosening and fracture displacement. The fractures of 23 patients were healed, and the healing time was 10 to 14 weeks with a mean of(12.0±1.1) weeks. The VAS score decreased from 7.96±0.93 before operation to 0.83±0.65 one year after operation. The range of knee flexion and extension activities increased from(20.30±8.69) ° before operation to 1 year after operation(127.39±6.55) °. Lysholm knee score increased from 18.48±4.00 before operation to 96.09±4.91 one year after operation(P<0.05).@*CONCLUSION@#The treatment of comminuted fracture of the lower pole of patella by lockedge suspension combined with three steel wires vertical fixation has reliable fixation and high fracture healing rate. It can meet the requirements of rapid rehabilitation and functional exercise, and the early clinical effect is satisfactory.

ABSTRACT

In this study, tibial shaft fracture has been treated with implants as numerically to investigate the stress behavior and the effect of plate material, position and length under pressure load. Plates of stainless steel, titanium alloy(Ti6Al4V), or CF-PEEK(CF50) were used to fix the tibial shaft comminuted fracture in different location and different working length. The maximum stress, the maximum micromotion of fracture and the stress shielding of cortex bone were analyzed. CF50 is more ideal biomechanical fixation material than traditional metal material for the treatment of tibial shaft comminuted fractures. In the treatment of tibial shaft comminuted fracture, lateral position and with relatively long working length of the plate have the advantages in micromotion, stress and stress shielding rate of the fracture end.

ABSTRACT

PURPOSE@#The aim of this study is to evaluate the application value of virtual surgical planning in the management of mandibular condylar fractures and to provide a reliable reference.@*METHODS@#This was a prospective randomized controlled study and recruited 50 patients requiring surgical treatment for their mandibular condylar fractures. The inclusion criteria were patients (1) diagnosed with a condylar fracture by two clinically experienced doctors and required surgical treatment; (2) have given consent for the surgical treatment; and (3) had no contraindications to the surgery. Patients were excluded from this study if: (1) they were diagnosed with a non-dislocated or only slightly dislocated condylar fracture; (2) the comminuted condylar fracture was too severe to be treated with internal reduction and fixation; or (3) patients could not complete follow-up for 3 months. There were 33 male and 17 female patients with 33 unilateral condylar fractures and 17 bilateral condylar fractures included. The 50 patients were randomly (random number) divided into control group (25 patients with 35 sides of condylar fractures) and experimental group (25 patients with 32 sides of condylar fractures). Virtual surgical planning was used in the experimental group, but only clinical experience was used in the control group. The patients were followed up for 1, 3, 6 and 12 months after operation. Variables including the rate of perfect reduction by radiological analysis, the average distance of deviation between preoperative and postoperative CT measurements using Geomagic software and postoperative clinical examinations (e.g., mouth opening, occlusion) were investigated for outcome measurement. SPSS 19 was adopted for data analysis.@*RESULTS@#The average operation time was 180.60 min in the experimental group and 223.2 min in the control group. One week postoperatively, CT images showed that the anatomic reduction rate was 90.63% (29/32) in the experimental group and 68.57% (24/35) in the control group, revealing significant difference (X2 = 4.919, p = 0.027). Geomagic comparative analysis revealed that the average distance of deviation was also much smaller in the experimental group than that in the control group (0.639 mm vs. 0.995 mm; t = 3.824, p < 0.001).@*CONCLUSION@#These findings suggest that virtual surgical planning can assist surgeons in surgical procedures, reduce operative time, and improve the anatomic reduction rate & accuracy, and thus of value in the diagnosis and treatment of condylar fractures.

ABSTRACT

PURPOSE@#The purpose of this study was to assess and compare elbow range of motion, triceps extension strength and functional results of type C (AO/OTA) distal humerus fractures treated with bilateral triceps tendon (BTT) approach and olecranon osteotomy (OO). At the same time, we are also trying to know whether BTT approach can provide sufficient vision for comminuted intra-articular fractures of the distal humerus, and whether it is convenient to convert to the treatment to total elbow arthroplasty (TEA) or OO.@*METHODS@#Patients treated with OO and BTT approaches for type C distal humerus fractures between July 2014 and December 2017 were retrospectively reviewed. Inclusion criteria include: (1) patients' age were more than 18 years old, (2) follow-up was no less than 6 months, and (3) patients were diagnosed with type C fractures (based on the AO/OTA classification). Exclusion criteria include: (1) open fractures (Gustillo type 2 or type 3), (2) treated by other approaches, and (3) presented with combined injuries of ipsilateral upper extremities, such as ulnar nerve. Elbow range of motion and triceps extension strength testing were completely valuated, when the fractures had healed. Assessment of functional results using the Mayo elbow performance score and complications were conducted in final follow-up. The data were compared using the two tailed Student's t-test. All data were presented as mean ± standard deviation.@*RESULTS@#Eighty-six patients of type C distal humerus fractures, treated by OO and BTT approach were retrospectively reviewed between July 2014 and December 2017. Fifty-five distal humerus fractures (23 males and 32 females, mean age 52.7 years) treated by BTT approach or OO were included in this study. There were 10 fractures of type C1, 16 type C2 and 29 type C3 according to the AO/OTA classification. Patients were divided into two surgical approach groups chosen by the operators: BTT group (28 patients) and OO group (27 patients). And the mean follow-up time of all patients was 15.6 months (range, 6-36 months). Three cases in BTT group were converted to TEA, and one converted to OO. Only one case in BTT group presented poor articular reduction with a step more than 2 mm. There were not significantly different in functional outcomes according to the Mayo elbow performance score, operation time and extension flexion motion are values between BTT group and OO group (p > 0.05). Complications and reoperation rate were also similar in the two groups. Triceps manual muscle testing were no significant difference in the two groups, even subdivided in elder patients (aged >60 years old).@*CONCLUSION@#BTT is a safe approach to achieve similar functional result comparing with OO. BTT were not suitable for every case with severe comminuted pattern, but it avoids the potential complications related to OO, and has no complications concerning with triceps tendon. It is convenient for open reduction internal fixation and flexible to be converted to OO, as well as available to be converted to TEA in elder patients.

ABSTRACT

OBJECTIVE@#To explore clinical effect of lateral locking compression plate combined with medial buttress plate in treating osteoporotic comminuted fractures of proximal humerus.@*METHODS@#From May 2017 to December 2021, 12 patients with osteoporotic comminution of proximal humerus were treated by lateral locking compression plates combined with medial buttress plates, including 5 males and 7 females, aged from 55 to 78 years old, bone mineral density(BMD) less than -2.5 g/cm3, the time from injury to operation was from 2 to 6 days. According to Neer classification, 7 patients were type Ⅲ, 4 patients were type Ⅳ and 1 patient was type Ⅵ. Postoperative complications, fracture healing and internal fixation were observed and Constant-Murley score of shoulder joint was used to evaluate clinical effects at 6 months after operation.@*RESULTS@#Postoperative wound healed well at stage I. All patients were followed up from 6 to 18 months. Humeral head collapse and necrosis occurred in 1 patient and humeral head varus in 1 patient. No impact of shoulder joint, internal fixation loosening occurred. Constant-Murley score at 6 months ranged from 45 to 90 points, and 6 patients got excellent result, 3 good, and 3 poor.@*CONCLUSION@#Locking compression plate combined with medial buttress plate could effectively reconstruct medial humeral column support and enhance fracture stability, and receive satisfactory clinical results. However, no control group was established in this study, and function of shoulder joint has not been evaluated many times after operation, so it cannot dynamically reflect changes of shoulder joint function.

ABSTRACT

Os ferimentos por arma de fogo (FAF) são um grande problema de saúde pública. Na face, a mandíbula é o local de maior incidência, sendo a região de corpo mandibular a mais atingida e as lesões aos tecidos moles frequentemente a ela associadas. Em alguns casos, tais ferimentos apresentam-se de difícil resolução, sobretudo, em casos de fraturas cominutivas e lesões de tecidos moles com alta complexidade. Isso torna o atendimento desses pacientes um desafio para cirurgiões buco-maxilo-faciais. Desta forma, o objetivo deste artigo é relatar um caso de FAF em terço inferior da face, com comprometimento de tecidos moles e mandíbula, pela equipe de Cirurgia e Traumatologia Bucomaxilofacial do Hospital Geral do Estado - Bahia. Paciente de 28 anos de idade, sexo feminino, vítima de FAF em terço inferior da face, por disparo acidental de espingarda. Ao exame clínico, pode-se observar ferimento perfuro-contuso em região de mandíbula e fratura cominutiva de corpo e ângulo mandibular à direita. A paciente foi submetida à cirurgia para remoção de fragmentos ósseos/corpos estranhos, fixação dos cotos com placa de reconstrução 2.4mm e sutura dos planos, em mesmo tempo cirúrgico, reestabelecendo a função da mandíbula. Portanto, devido à fisiopatologia variável dos FAF na mandíbula, não se indica um único padrão de tratamento para as fraturas cominutivas. Além disso, é indispensável o emprego de protocolos de limpeza cirúrgica imediata e antibioticoterapia nos casos com alto grau de cominuição, bem como, sugere-se realizar o tratamento definitivo o mais breve possível(AU)


Firearm injuries (FIs) are a major public health problem. On the face, the mandible is the place with the highest incidence of this trauma, with the mandibular body region being the most affected and the lesions to the soft tissues frequently associated with it. In some cases, such injuries are difficult to resolve, especially in cases of comminuted fractures and soft tissue injuries with high complexity. This makes the care of these patients a challenge for oral and maxillofacial surgeons. Thus, the objective of this article is to report a case of care for a FAF victim in the lower third of the face, with soft tissue and mandible involvement, by the Maxillofacial Surgery and Traumatology team at the Hospital Geral do Estado - Bahia. 28-year-old female patient, victim of FAF in the lower third of the face, due to acidental shotgun firing. On clinical examination, a perforated-blunt wound can be seen in the mandible region and comminuted fracture of the body and angle of the mandible on the right. The patient underwent surgery to remove bone fragments / foreign bodies, fix the stumps with a 2.4 mm reconstruction plate and suture the planes, at the same surgical time, reestablishing the function of the mandible. Therefore, due to the variable pathophysiology of FAF in the mandible, a single treatment pattern is not indicated for comminuted fractures. In addition, it is essential to use immediate surgical cleaning protocols and antibiotic therapy in cases with a high degree of comminution, as well as, it is suggested to carry out the definitive treatment as soon as possible(AU)

ABSTRACT

La artrosis es una enfermedad progresiva de las articulaciones sinoviales que causa dolor, impotencia funcional, discapacidad, y degeneración progresiva de la articulación. En sus tratamientos, sobre todo en etapas tempranas, existen distintas intervenciones para evitar tanto su desarrollo y progresión como también para lograr un adecuado manejo de los síntomas, y hay tratamientos médicos orales no convencionales con evidencia controvertida. El objetivo de este trabajo es proporcionar una actualización, dirigida a especialistas en Ortopedia y Traumatología, respecto a la evidencia actual sobre las terapias complementarias orales en el tratamiento de la artrosis de rodilla. Se hace referencia a los métodos fármacológicos complementarios más usados y estudiados, mencionando el método de acción y las consecuencias estudiadas sobre la artrosis de rodilla. Se finaliza con una tabla de recomendaciones basada en evidencia actual.


Osteoarthritis (OA) is a progressive disease of the synovial joints that causes pain, functional impairment, disability, and progressive degeneration of the joint. Regarding its treatments, especially in early stages, there are different interventions to avoid its development and progression and also to achieve an adequate management of symptoms, and there are unconventional oral medical treatments with controversial evidence. The objective of the present paper is to provide an update, to specialists in Orthopedics and Traumatology, regarding the current evidence on complementary oral therapies in the treatment of knee osteoarthritis. References are made to the most widely used and studied complementary pharmacological methods, mentioning the method of action and the consequences studied on knee osteoarthritis. The article ends with a table of recommendations based on current evidence.

ABSTRACT

OBJETIVO Comparar los resultados clínicos, funcionales e imagenológicos de dos técnicas quirúrgicas para el manejo de fracturas conminutas de patela: con y sin eversión patelar. MÉTODOS En una serie de casos retrospectivos de fracturas conminutas de patela tratadas en el mismo centro entre 2014 y 2017, con un seguimiento ≥ 3 meses, se hizo una comparación entre el grupo con eversión y el grupo sin eversión. Los criterios de exclusión fueron patelectomía parcial o total, reinserción tendínea, o rehabilitación incompleta. Las variables analizadas fueron edad, sexo, tabaquismo, diabetes mellitus, energía del accidente, tipo de fractura, variables quirúrgicas (banda de tensión, tornillos, alambres, nudos, cerclaje circular), rango de movimiento (RDM) articular postoperatorio, presencia de osteosíntesis sintomática, puntaje de escalas funcionales (de Tegner-Lysholm y de Kujala) al alta definitiva, complicaciones (rigidez articular, infección, trombosis venosa profunda), y variables imagenológicos con tomografías computarizadas pre- y postoperatorias (brecha, desnivel articular > 2 mm, elementos de fijación intraarticular). RESULTADOS En total, 20 de 22 pacientes, 13 con eversión y 7 sin eversión, cumplieron con los criterios de selección. El seguimiento fue de 3 a 12 meses, y no hubo diferencias estadísticamente significativas respecto a las variables demográficas entre ambos grupos, lo cual los hace comparables. Destacaron el tiempo desde el ingreso al alta, con 7 meses para los pacientes con eversión y 5 meses para los sin eversión (p = 0.032), la proporción de pacientes con desnivel articular > 2 mm, con 7.7% para los con eversión y 14.3% para los sin eversión (p = 0.016), y una tendencia a resultados superiores en escalas funcionales para el grupo con eversión. CONCLUSIÓN El tratamiento de fracturas conminutas de patela con eversión parece ser una alternativa viable dados sus resultados imagenológicos y funcionales superiores a los de la técnica habitual.


PURPOSE To compare the clinical, functional and imaging outcomes of two surgical techniques for the treatment of comminuted patellar fractures: with and without eversion. METHODS In a retrospective series of cases of comminuted patellar fractures treated at a single center between 2014 and 2017, with a follow-up 3 months , we performed a comparison between the eversion group and the non-eversion group. The exclusion criteria were partial or total patellectomy, tendon reinsertion, or incomplete rehabilitation. The variables analyzed were age, gender, smoking, diabetes mellitus, the energy of the accident, the fracture type, surgical variables (tension band, screws, wires, knots, circular cerclage), postoperative joint range of motion (ROM), presence of symptomatic osteosynthesis, the scores on the functional scales (of Tegner-Lysholm and of Kujala) at the final discharge, complications (joint stiffness, infection, deep vein thrombosis), and pre- and postoperative computed tomography imaging variables (gap, step-off > 2mm, intra-articular fixation elements). RESULTS In total, 20 out of 22 patients, 13 undegoing eversion and 7 not undergoing eversion, met the selection criteria.. The follow-up ranged from 3 to 12 months, and there were no statistically significant differences regarding the demographic variables between both groups, which makes them comparable. The most remarkable results were the time from admission to final discharge, of 7 months for the patients in the eversion group, and of 5 months for those in the non-eversion group (p » 0.032), the proportion of patients with a step-off > 2 mm, with 7.7% for the eversion group and 14.3% for the non-eversion group (p » 0.016), and a tendency towards higher scores in the functional scales for the eversion group. CONCLUSION The treatment of comminuted patellar fractures with eversion seems to be a viable alternative, given its superior imaging and functional results compared to those of the usual technique.

ABSTRACT

Introducción: Las lesiones traumáticas con pérdida de cobertura cutánea de la región del tobillo y pie, constituyen un gran reto para el cirujano ortopédico por la exposición y destrucción de tejidos nobles, difíciles de solucionar por ser una zona que presenta escaso tejido adiposo, múltiples tendones, poco volumen muscular, varias prominencias óseas y piel poco elástica. Objetivo: Presentar el colgajo sural de flujo reverso como una buena alternativa para tratar la fractura conminuta cerrada de tibia con pérdida masiva de la piel del tobillo y calcáneo en toda su circunferencia, incluida la almohadilla adiposa de la cara plantar. Presentación del caso: Se presenta paciente de 24 años que sufrió accidente de tránsito con fractura conminuta y cerrada de tibia derecha, además de una herida tipo colgajo que dejó expuesto el calcáneo y la región del tobillo. Luego de colocar fijador externo RALCA para fijar la fractura, se realizó colgajo sural en isla de flujo reverso para cubrir el defecto en la cara plantar y posterior del calcáneo, más injerto libre de piel tomado de la cara antero externa del muslo ipsilateral. Estos procedimientos fueron realizados en dos tiempos quirúrgicos. Conclusiones: El colgajo sural de flujo reverso demostró ser una de las mejores alternativas para la cobertura de lesiones desde el tercio medio de la pierna hasta el pie, por lo que debería ser conocido no solo por cirujanos plásticos, sino también por cirujanos ortopédicos y traumatólogos que lo incorporen a su arsenal terapéutico para su realización(AU)


Introduction: Traumatic injuries with loss of skin coverage of the ankle and foot region constitute great challenge for the orthopedic surgeon due to the exposure and destruction of noble tissues, difficult to solve because this area has little adipose tissue, multiple tendons , little muscle volume, several bony prominences and not very elastic skin. Objective: To establish that the reverse flow sural flap is a good alternative to treat closed comminuted fracture of the tibia with massive skin loss of the entire circumference of the ankle and calcaneus, including the plantar face fat pad. Case report: We report the case of a 24-year-old patient who suffered a traffic accident with a comminuted and closed fracture of the right tibia, as well as a flap-type wound that exposed the calcaneus and the ankle region. After placing RALCA external fixator to fix the fracture, a reverse flow island sural flap was made to cover the defect on the plantar and posterior aspect of the calcaneus, and a free skin graft taken from the anterior external aspect of the ipsilateral thigh. These procedures were performed in two surgical stages. Conclusions: The reverse flow sural flap proved to be one of the best alternatives for the coverage of injuries from the middle third of the leg to the foot, which is why it should be known not only by plastic surgeons, but also by orthopedic surgeons and traumatologists and to incorporate this alternative into their therapeutic arsenal(AU)

ABSTRACT

OBJECTIVE@#To compare the effects of tension band combined with patellar cerclage and memory alloy patellar concentrator fixation in the treatment of comminuted fracture of the lower pole of patella.@*METHODS@#From July 2015 to July 2019, 60 patients with distal patellar fracture were treated and were divided into two groups according to different operation methods. In group A, 30 patients were fixed with memory alloy patellar concentrator (NiTi PC), 17 males and 13 females, aged 20 to 71 (39.4±9.9) years, including 19 cases of falling injury, 9 cases of traffic injury and 2 cases of sports injury. The time from injury to operation was 10 to 75 (33.1±7.8) hours; 30 cases in group B were fixed with tension band andcerclage, 15 males and 15 females, aged 21 to 76 (38.6±10.2) years, including 17 cases of falling injury, 12 cases of traffic injury and 1 case of smashing injury. The time from injury to operation was 10 to 91 (34.5±9.1) hours. The curative effects of two groups were observed and compared.@*RESULTS@#All 60 patients were followed up for 9 to 30 months. There was no significant difference in intraoperative bleeding, operation time, follow-up time and fracture healing time between the two groups. Six months after operation, according to the Bostman function score of knee joint:30 cases in group A, the total score was 28.6±4.7, of which 26 cases were excellent and 4 cases were good. The total score of 30 cases in group B was 25.5±4.4, of which 20 cases were excellent, 8 cases were good and 2 cases were poor. There were significant differences in Bostman total score and curative effect evaluation between two groups (@*CONCLUSION@#Memory alloy patellar concentrator is strong and reliable in the treatment of inferior patellar fracture. It can take early rehabilitation exercise after operation, with good recovery of joint function and range of motion and less complications.
