RESUMO

OBJECTIVES: To determine whether the initial radiographic displacement of humeral shaft fractures is associated with failure of nonoperative management. DESIGN: Retrospective cohort study. SETTING: Urban level 1 trauma center. PATIENTS/PARTICIPANTS: 106 patients with humeral shaft fractures (OTA/AO 12) initially managed nonoperatively. INTERVENTION: Functional bracing. MAIN OUTCOME MEASUREMENTS: Failure of nonoperative management, defined as conversion to surgery, malunion, and delayed union/nonunion. RESULTS: Nonoperative management failed in 33 (31%) of 106 included patients with 27 patients (25%) requiring surgery. On multivariate analysis, female sex [odds ratio (OR): 3.50, 95% confidence interval (CI): 1.09 to 11.21], American Society of Anesthesiologist classification >1 (OR: 7.16, CI: 1.95 to 26.29), initial fracture medial/lateral (ML) translation (OR: 1.09, CI: 1.01 to 1.17, per unit change), and initial fracture anterior-posterior (AP) angulation (OR: 1.09, CI: 1.02 to 1.15, per unit change) were independently associated with failure of nonoperative management. Initial fracture displacement values that maximized the sensitivity (SN) and specificity (SP) for failure included an AP angulation >11 degrees (SN 75%, SP 64%) and ML translation >12 mm (SN 55%, SP 75%). The failure rate in patients with none, 1, or both of these fracture parameters was 3.1% (1/32), 35.6% (20/56), and 66.6% (12/18), respectively. CONCLUSIONS: Nearly one-third of patients experienced failure of initial nonoperative management. Failure was found to be associated with greater initial fracture AP angulation and ML translation. Fracture displacement cut-off values were established that may be used by surgeons to counsel patients with these injuries. LEVEL OF EVIDENCE: Prognostic Level III.

RESUMO

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.

RESUMO

Introducción: Las fracturas del húmero distal corresponden al 2% de todas las fracturas. Son los pacientes más añosos, los que presentan mayor desafío terapéutico. Suelen presentarse con huesos osteoporóticos, lo que conlleva a producir fracturas con mayor conminución articular y metafisaria; así como también dificultar una fijación estable y rígida de las mismas, que permita una movilidad precoz. Estas características generan controversia a la hora de elegir el tratamiento adecuado. El objetivo de este estudio es revisar la bibliografía de la última década, acerca de cuál es la mejor opción terapéutica para las fracturas de húmero distal en pacientes añosos. Materiales y métodos: Se realizó una búsqueda sistematizada a través de los buscadores electrónicos PubMed y Timbó en agosto 2019. La búsqueda llego a un total de 475 artículos, de los cuales se seleccionaron 24 según criterios de inclusión y exclusión. Discusión: La mayoría de los estudios analizados son estudios de serie de casos retrospectivos. En los trabajos revisados, existen fracturas tanto extra como intra-articulares. Se analizaron los resultados de los distintos tratamientos realizados según parámetros clínicos, scores funcionales y complicaciones. Conclusiones: El tratamiento conservador es una opción válida para aquellos pacientes en los que el terreno no permita una intervención quirúrgica. Para las fracturas tipo extra-articulares y parcialmente articulares, la reducción abierta y fijación interna es el tratamiento de elección. Para las fracturas articulares completas, no hay diferencias significativas en cuanto a scores utilizados entre la reducción abierta y fijación interna con la artroplastia de codo. Faltan estudios prospectivos que comparen ambos tratamientos.

Introduction: Distal humerus fractures account for 2% of all fractures. It is the elderly patients who present the greatest therapeutic challenge. Osteoporotic bones, more common in this population, lead to the production of fractures with greater joint and metaphyseal comminution. As a result, stable and rigid fixation becomes more difficult, hindering early mobility. These characteristics generate controversy when choosing the appropriate treatment. The aim of this study is to review the literature of the last decade regarding the best therapeutic option for distal humerus fractures in elderly patients. Methods: A systematized search was performed through the electronic search engines PubMed and Timbó in august 2019. The search reached a total of 475 articles, of which 24 were selected according to inclusion and exclusion criteria. Discussion: Most of the studies analyzed are retrospective case series studies. In the articles reviewed, there are both extra and intra-articular fractures. The results of the different treatments performed were analyzed according to clinical parameters, functional scores and complications. Conclusions: Conservative treatment is a valid option for those patients where the terrain does not allow surgical intervention. For extra-articular and partial-articular fractures, open reduction and internal fixation is the treatment of choice. For complete articular fractures, there are no significant differences in scores used between open reduction and internal fixation and elbow replacement. There is a lack of prospective studies comparing both treatments.

RESUMO

BACKGROUND: Humeral stress fractures are rare injuries usually related to sports practice and joint overload without a direct trauma. A proximal humeral stress fracture has never been reported in a CrossFit athlete. CASE PRESENTATION: We report a stress fracture in the humerus of a 22-year-old woman after intense CrossFit training. Patient's previous medical history included amenorrhea and reduced Vitamin D levels. The patient was treated conservatively and resumed CrossFit training after she was advised not to until follow up imaging. CONCLUSIONS: We present the MRI features of the case and emphasize the difficulties in diagnosis due to multiple possible causes of shoulder pain in a CrossFit athlete and by negative findings on early radiographs. Hormonal variations, Vitamin D insufficiency and the patient's attitude towards exercise were important factors that contributed for the stress injury after weight-lifting in CrossFit.

RESUMO

Pediatric distal humerus fractures are common, and numerous variations can occur depending on patient's age, position of the extremity at the time of injury, and energy of impact. Classic injury patterns include the flexion/extension supracondylar humerus, medial epicondyle, lateral condyle, and the transphyseal distal humerus. We describe our treatment philosophy for pediatric elbow fractures and how these principles were applied to some unusual fractures that presented to our institution.

RESUMO

BACKGROUND: Nonoperative treatment has historically been considered the standard for fractures of the shaft of the humerus. Minimally invasive bridge-plate osteosynthesis for isolated humeral shaft fractures has been proven to be a safe technique, with good and reproducible results. This study was designed to compare clinical and radiographic outcomes between patients who had been treated with bridge plate osteosynthesis and those who had been managed nonoperatively with a functional brace. METHODS: A prospective randomized trial was designed and included 110 patients allocated to 1 of 2 groups: surgery with a bridge plate or nonoperative treatment with a functional brace. The primary outcome was the Disabilities of the Arm, Shoulder and Hand (DASH) score at 6 months. The score on the Short Form-36 (SF-36) life-quality questionnaire, complications of treatment, Constant-Murley score for the shoulder, pain level, and radiographic results were assessed as secondary outcomes. Participants were assessed at 2 weeks; 1, 2, and 6 months; and 1 year after the interventions. RESULTS: The mean DASH score of the bridge plate group was statistically superior to that of the functional brace group (mean scores, 10.9 and 16.9, respectively; p = 0.046) only at 6 months. The bridge plate group also had a significantly more favorable nonunion rate (0% versus 15%) and less mean residual angular displacement seen on the anteroposterior radiograph (2.0° versus 10.5°) (both p < 0.05). No difference between the groups was detected with regard to the SF-36 score, pain level, Constant-Murley score, or angular displacement seen on the lateral radiograph. CONCLUSIONS: This trial demonstrates that, compared with functional bracing, surgical treatment with a bridge plate has a statistically significant advantage, of uncertain clinical benefit, with respect to self-reported outcome (DASH score) at 6 months, nonunion rate, and residual deformity in the coronal plane as seen on radiographs. LEVEL OF EVIDENCE: Therapeutic Level I. See Instructions for Authors for a complete description of levels of evidence.

RESUMO

BACKGROUND: Mobile imaging, such as viewing radiographs as text messages, is increasingly prevalent in clinical settings. The purpose of this study was to determine whether remote diagnosis of pediatric elbow fractures using smartphone technology is reliable. In addition, this study aimed to determine whether the assessment regarding the decision for operative treatment is affected by evaluation of images on a mobile device as opposed to standard picture archiving and communication system (PACS). METHODS: Standard anteroposterior and lateral radiographs of 50 pediatric elbow trauma cases were evaluated by 2 fellowship-trained pediatric orthopaedic surgeons and 2 senior orthopaedic residents. Raters were asked to classify the case as any of 6 diagnoses: supracondylar humerus, lateral condyle, medial epicondyle, radial neck fracture, positive posterior fat pad sign, or normal pediatric elbow. Raters were asked to choose operative or conservative treatment. After 1 week, photographs of the same images were taken from a standardized distance from a computer monitor with an iPhone 5 camera and transmitted by multimedia messaging to each rater. The same questions were again posed to raters. Interobserver and intraobserver reliabilities were calculated by Cohen κ-statistics with bootstrapped 95% confidence intervals. RESULTS: Intraobserver reliability of classification of injuries on PACS compared with smartphone images was excellent, with an overall κ of 0.91. Treatment decision also demonstrated excellent intraobserver reliability (PACS vs. smartphones) with a κ of 0.86 for all raters. CONCLUSIONS: Diagnosis of pediatric elbow injuries can be made equally reliably based on either PACS or transmitted multimedia messaging images taken with an iPhone camera from a computer screen and viewed on a smartphone. Treatment decisions can also be made reliably based on either image modality. CLINICAL RELEVANCE: Using smartphones to transmit and display radiographs, which is common in current clinical practice, is effective and reliable for diagnosis and treatment planning of pediatric elbow injuries.

RESUMO

OBJECTIVES: To determine if there is a shift in the treatment of children with medial epicondyle fractures toward children's hospitals, and to explore potential confounders of any observed effect. STUDY DESIGN: The Healthcare Cost and Utilization Project Kids' Inpatient Database was used to examine the epidemiology of medial epicondyle fractures, particularly with attention to whether they were admitted to a general hospital or a children's hospital (defined as free-standing children's hospitals, specialty children's hospitals, and children's units within general hospitals). Age and insurance payer status were also collected and evaluated as potential confounders. RESULTS: The proportion of medial epicondyle hospital discharges from children's hospitals increased (from 29%-46%; P < .001), and the proportion of discharges from general hospitals declined over the study period (from 71%-42%; P < .001). Age and insurance payer status both remained consistent throughout the study period and did not contribute to this finding. CONCLUSIONS: This study demonstrates an increase in the proportion of discharges for pediatric medial epicondyle fractures from children's hospitals. Although this finding is likely multifactorial, it may represent increasing subspecialization and increasing medical liability when treating children. Children's hospitals should identify those conditions which will continue to increase in number and consider constructing clinical pathways in order to optimize delivery of care and resource utilization.

RESUMO

BACKGROUND: Supracondylar humerus fractures are common in children between 5-7 years of age and more frequent in the males, 90-95% of these fractures are in extension mechanism, the urgency of immediate attention is to prevent complications and sequelae. OBJECTIVE: To establish the clinical and epidemiological profile of supracondylar humerus fractures, in a General Regional Hospital from the Instituto Mexicano del Seguro Social in Yucatan Mexico, during 2011-2013. MATERIAL AND METHODS: A cross-sectional study. Strength association was measured by odds ratios and statistical significance with chi(2) test, p value was considered in < 0.05 RESULTS: 56 cases were analyzed, the mean age was 2.6 ± 5.33 years, the mechanism of injury was falling over at home, male gender is associated with extent injure mechanism (OR 5.6, 95% CI 1.0-30.1, p = 0.03), we observed that at most time elapsed between injury and medical means more hospital days (r = 0.40; p = 0.002), surgical treatment was established in 44 cases (78.6%), 18 (40.9%) with closed technique and placement of cloves and 26 (59.1%) with open reduction, in 100% cross configuration was used, ten complications were reported. CONCLUSIONS: Supracondylar humerus fractures are a common injury in children, males are more likely to be injured by extension, and the speed in medical treatment is an important issue.

RESUMO

BACKGROUND: The AAOS guidelines suggest operative fixation of all type 2 supracondylar humerus fractures. Not all type 2 fractures are the same. Wilkins type 2a fractures have intrinsic stability. The purpose of this paper is to report closed reduction and single-pin fixations for Wilkins 2a fractures. METHODS: Fifteen consecutive type 2a fractures treated with single-pin fixation were prospectively evaluated. Procedure notes, age, sex, side involved, duration of immobilization, and complications were recorded. Radiographs were measured for the lateral humerocapitellar line and the humeral ulna angle. At final follow-up the carrying angle, range of motion, and the Flynn criteria were recorded. RESULTS: The average age of patients was 5 years (age range, 1 to 9 y). Three females and 12 males were studied. Eight right elbows and 7 left elbows were injured. A 0.0625 K-wire was used in 2 cases and a 2 mm K-wire was used in 13 cases. On preoperative lateral radiographs, the anterior humeral line did not intersect the capitellum. On postoperative radiographs, the anterior humeral line intersected the middle third of the capitellum. Following pinning, the elbow was immobilized in a long-arm cast in pronation with elbow at 75 degrees of flexion. The cast and pin were removed at an average of 27 days (range, 25 to 31 d). One patient was lost to follow-up. The remaining 14 patients were followed for at least 3 months. At final follow-up, the carrying angle was within 2 degrees of the opposite elbow and ROM was within 3 degrees of the opposite elbow in all cases. Final Flynn criteria were excellent in all 14 patients. There were no complications. CONCLUSIONS: Treatment of supracondylar fractures has evolved from selective pinning of type 2 fractures to pinning all type 2 fractures. The results of the current study demonstrate the efficacy of using a single lateral entry pin for stabilization of type 2a fractures in children. LEVEL OF EVIDENCE: Level III.

RESUMO

Objetivo: avaliar clinica e radiologicamente os resultados obtidos com a redução aberta e a fixação interna das fraturas graves da extremidade proximal do úmero (FGEPU) na população com idade igual ou superior a 60 anos. Métodos: entre junho de 1992 e fevereiro de 2011, o Grupo de Ombro e Cotovelo do Departamento de Ortopedia e Traumatologia da Faculdade de Ciências Médicas da Santa Casa de São Paulo tratou, com redução aberta e fixação interna, 21 pacientes com FGEPU e com idade superior a 60 anos. Desses, 18 foram reavaliados. Resultados: dois pacientes evoluíram com resultados excelentes, 12 bons, três regulares e um ruim. Portanto, verificamos que 77,7% evoluíram com bons e excelentes resultados. Todos os pacientes estavam satisfeitos com o tratamento e apenas três não retornaram às atividades prévias. As médias de mobilidade pós-operatória foram de 122° de elevação (90° -150°), 39° de rotação lateral (20 °-60°) e T11 de rotação medial (T5 a Glúteo). Conclusão: a redução aberta e a fixação interna das FGEPU podem ser indicadas também para pacientes idosos e obtivemos 77,7% de bons e excelentes resultados. Estatisticamente (p < 0,05), a redução anatômica da fratura mostrou-se importante para a obtenção de bons resultados. .

Objective: To evaluate clinical and radiological results with open reduction and internal fixation of severe fractures of the proximal humerus in the patients over the age of 60 years. Methods: Between June 1992 and February 2011, 21 patients with FGEPU over the age of 60 years were treated by open reduction and internal fixation at the Group of Shoulder and Elbow Department of Orthopaedics and Traumatology of Santa Casa de São Paulo Medical School. 18 patients were reviewed. Results: Two patients had excellent results, 12 good, three regular and one bad. Therefore, we find that 77.7% of these had good and excellent results. All patients were satisfied with the treatment and only three patients did not return to previous activities. Mean postoperative mobilities were 122° elevation (90-150°), 39 lateral rotation (20-60°) and medial rotation of T11 (T5 to sacro iliac joint). Conclusion: Open reduction and internal fixation of FGEPU may also be indicated for elderly patients and obtained 77.7% of good and excellent results. Statistically ( p < 0.05), the anatomical reduction of the fracture was found to be important for obtaining good results. .

RESUMO

Uno de los pilares fundamentales en el tratamiento conservador de las fracturas diafisarias del húmero ha sido el uso del yeso colgante como método de inmovilización, por lo que se decició aplicar dicho tratamiento en un paciente después de haber realizado el diagnóstico de dicha afección. Se evaluó la eficacia del método empleado a través del seguimiento periódico de la evolución clínica e imaginológica de la lesión, obteniéndose la consolidación de la fractura sin que se apreciara complicación alguna, resultado que concuerda con la literatura mundial, la cual refiere la importancia y resultados positivos del método empleado. Teniendo en cuenta lo práctico, económico y útil que resulta el mismo los autores consideraron oportuno presentar esta experiencia con el objetivo de promover la extensión práctica del tratamiento conservador de la fractura diafisaria del húmero.

One of the main pillars of the humerus dyaphisial fracture conservative treatment has been the usage of the hanging plaster cast as an immobilization method, so we decided to use that treatment in a patient after diagnosing that condition. We evaluated the efficacy of the used method periodically following the clinical and imaging evolution of the lesion, obtaining the consolidation of the fracture without any complication, result agree with the international literature that refers the importance and positive outcomes of the used method. Taking into account its suitability, effectiveness, and usefulness we considered it opportune to present this experience with the objective of promoting the practical extension of the humerus dyaphisial fracture conservative treatment.

RESUMO

Non-accidental injuries in children are an important cause of morbidity and mortality in this population. Fractures are the second most common clinical manifestation of child abuse. The fracture of the femur is associated in more than 60% of child abuse in children younger than 3 years. The objective was to review the literature on child abuse in the major databases and report a rare case of bilateral subtrochanteric femur fractures associated with unilaterall humeral fracture in a 28-day newborn. The orthopedic surgeon is often the first physician to evaluate these children, so a high degree of suspicion, and a physical examination and a detailed clinical history is mandatory when evaluating a newborn with musculoskeletal injuries.

Lesões não acidentais em crianças são uma importante causa de morbidade e mortalidade nesta população. Fraturas são a segunda causa mais comum de manifestação clínica de maus tratos. A fratura do fêmur está associada em mais de 60% dos casos a maus tratos em crianças menores de 3 anos. O objetivo do trabalho foi fazer uma revisão da literatura nas principais bases de dados a respeito dos maus-tratos infantis e relatar um caso raro de fratura subtrocantérica bilateral de fêmur associada com fratura umeral unilateral em um recém-nascido de 28 dias. O ortopedista muitas vezes é o primeiro médico a avaliar essas crianças; portanto, um alto grau de suspeição, além de um exame físico minucioso e uma história clínica detalhada, é mandatório ao se avaliar um recém-nascido com lesões musculoesqueléticas.

RESUMO

OBJECTIVE: Evaluate the clinical and radiological results of hemiarthroplasty for treatment of complex proximal humerus fractures. METHODS: Sixty-seven patients were included, with follow-up of 12 to 62 months. Mean age was 65 years (44 to 88), and 47 patients were female (70%). Clinical assessment was performed using the University of California Los Angeles score (UCLA) and measurement of range of motion (ROM) according to the American Academy of Orthopaedic Surgeons criteria. A standardized radiological evaluation was conducted, with special attention to healing and position of tuberosities. Patients were divided into two groups: A (anatomical healing of tuberosities) and B (without anatomical healing of tuberosities). Statistical analyses were performed using the t test. Level of significance was set at p < 0.05. RESULTS: Considering the entire sample, the mean UCLA score was 26 points, with 8 points for pain and 64 patients subjectively satisfied (96%). The mean values for active ROM were 104º of forward flexion and 36º of external rotation. In group A, with 33 patients, we found a mean of 122º forward flexion and 29.5 points on UCLA. In group B the mean forward flexion were 87º and 22.7 points for UCLA. Comparing these parameters in the two groups, we found statistically significant differences for both forward flexion (p < 0.0001) and UCLA. (p < 0.0001). CONCLUSION: We conclude that hemiarthroplasty for treatment of complex proximal humerus fractures has a low incidence of complications and a high subjective satisfaction rate, with favorable results related to pain. A good functional result is less predictable and depends on anatomical reestablishment of proximal humerus anatomy, particularly healing of the greater tuberosity.

OBJETIVO: Avaliar os resultados funcionais e radiográficos dos pacientes submetidos à hemiartroplastia para tratamento das fraturas complexas da extremidade proximal do úmero. MÉTODOS: Foram incluídos 67 pacientes, com seguimento que variou entre 12 e 62 meses. A média de idade foi de 65 anos (44 a 88) e 47 pacientes eram do sexo feminino (70%). Os pacientes foram avaliados clinicamente por meio da avaliação da amplitude de movimentos (ADM) e do escore funcional da University of California Los Angeles (UCLA). A avaliação radiográfica foi feita de forma padronizada com divisão dos pacientes em dois grupos: A (consolidação do tubérculo maior em posição anatômica) e B (ausência de consolidação anatômica do tubérculo maior). Na análise estatística consideramos significativos os achados com p < 0,05. RESULTADOS: A pontuação média do UCLA foi de 26 pontos, com média de oito pontos para dor e 64 pacientes satisfeitos subjetivamente (96%). Na avaliação da amplitude de movimento (ADM) ativa encontramos uma média de 104º de flexão anterior e 36º de rotação lateral. No grupo A, com 33 pacientes, encontramos uma média de 122º de flexão anterior e pontuação média da UCLA de 29,5. No grupo B as médias foram de 87º para flexão anterior e de 22,7 pontos para a UCLA. Comparando esses parâmetros encontramos diferenças estatisticamente significativas tanto para a flexão anterior (p < 0,001) quanto para a UCLA (p < 0,001). CONCLUSÃO: A hemiartroplastia no tratamento das fraturas complexas da extremidade proximal do úmero apresenta alto índice de satisfação subjetiva e um resultado favorável com relação à dor. Um resultado funcional satisfatório é menos previsível e depende do restabelecimento preciso da morfologia da extremidade proximal do úmero, especialmente da consolidação anatômica do tubérculo maior.

RESUMO

OBJETIVO: Avaliamos o tratamento da pseudoartrose de fratura diafisária do úmero com placa de compressão dinâmica de janeiro de 2002 a dezembro de 2009. MÉTODOS: Vinte e dois pacientes foram tratados durante o período do estudo. O trauma foi a causa predominante de lesão em 86,4% dos pacientes. RESULTADOS: A pseudoartrose foi atrófica em 81,8% e hipertrófica em 18,2% dos indivíduos. Havia lesão primária do nervo radial nervo em 27,3% dos pacientes. Todos os participantes tinham fratura fechada à apresentação e 81,2% deles tinham recebido tratamento anterior de traditional bone setters (pessoa que faz a redução de ossos quebrados ou deslocados, geralmente sem ser médico licenciado) e 18,8% tinham falha do tratamento conservador com gesso. O tempo médio até a união foi 16 semanas. O tratamento anterior com traditional bone setters afetou significantemente o tempo de consolidação da fratura (p < 0,05). Todas as fraturas tiveram consolidação bem-sucedida. CONCLUSÃO: Concluímos que o uso de placa de compressão dinâmica continua a ser uma opção eficaz de tratamento da pseudoartrose de fratura diafisária do úmero. Nível de evidência III, Estudo retrospectivo.

OBJECTIVE: We evaluated the treatment of nonunion of humeral shaft fracture with dynamic compression plate from January 2002 to December 2009. METHODS: Twenty two patients were treated over the study period. Trauma was the predominant cause of injury in 86,4% of the patients. RESULTS: Nonunion was atrophic in 81,8% and hypertrophic in 18,2% of the individuals. There was a primary injury of the radial nerve in 27,3% of the patients. All the participants had closed fracture at presentation, and 81,2% had received previous treatment from traditional bone setters and 18,8% had failure of the conservative cast management.The average time to healing was 16 weeks. Previous treatment from traditional bone setters significantly affected the time to fracture healing (p<0,05). All fractures had successful union. CONCLUSION: It was concluded that dynamic compression plating remains an effective treatment option for nonunion of humeral shaft fracture. Level of Evidence III, Retrospective study.

RESUMO

Introdução: As fraturas supracondilianas do úmero são frequentes na infância e correspondem a 50 ou 60% das fraturas do cotovelo. A redução anatômica associada ou não à osteossíntese é a chave para o sucesso do tratamento independentemente do método terapêutico. Objetivo: Este trabalho teve como objetivo avaliar os resultados funcionais e radiográficos de 129 crianças cujas fraturas foram classificadas de acordo com o método de Gartland. Método: Utilizamos o protocolo prospectivo desenvolvido pela Comissão de Educação Continuada da Sociedade Brasileira de Ortopedia e Traumatologia. Resultados: Obtivemos bons resultados na avaliação final nas fraturas do tipo I e II quando aplicado o método conservador e incruento com baixos índices de complicações (3,4%). Nas do tipo III, observamos maior número de complicações, entre elas lesões nervosas traumáticas (16,2%) e o cúbito valgo (3,2%). Conclusões: Para tratamento preconizamos a redução incruenta com fixação percutânea com fios de Kirschner cruzados. A redução aberta está indicada nos casos em que a redução fechada não foi bem sucedida, e a tração pré-operatória teria indicação restrita. Não preconizamos a fisioterapia para todos os pacientes, a não ser quando estes não apresentaram recuperação espontânea após um mês da retirada do gesso ou na vigência de complicação neurológica.

Introduction: The humeral supracondylar fractures are common in childhood and correspond to 50 or 60% of the elbow fracture. Anatomical reduction associated or not with osteosynthesis is the subject for the success of treatment independent of the therapeutic method. Objective: This paper had the purpose to analyze the functional and radiographic results in 129 children whose fractures were classified according to Gartland method. Method: We applied the prospective protocol developed by the Educational Committee of the Brazilian Orthopedic and Trauma Society. Results: We observed good results at the final evaluation in fractures classified as type I and II when conservative and non-operative methods were applied with lower rate of complications (3,4%). In type III fractures we observed higher percentage of complications as traumatic neurological damage (16,2%) and cubitus valgus (3,2%). Conclusions: For the treatment, we recommend closed reduction with percutaneous fixation using crossed Kirschner wires. Open reduction is indicated in cases which closed reduction was not well succeeded and pre-operative traction should has restrict indication. We do not recommend physical therapy for all patients, only in these ones that did not present spontaneous recovery after one month of the cast take-off or in the presence of neurologic complication.

RESUMO

As fraturas da diáfise do úmero (FDU) representam 3 por cento das fraturas do aparelho locomotor; o terço médio da diáfise direita é o mais acometido. Seu tratamento é, na sua maioria, realizado por meio de métodos não cirúrgicos, mas as indicações cirúrgicas nas FDU são adotadas em situações cada vez mais frequentes. A diversidade de opiniões torna difícil o consenso sobre qual o tipo de osteossíntese, qual a técnica cirúrgica, a quantidade e a qualidade dos materiais de síntese a serem utilizados. Temos a impressão de que o melhor método para o tratamento cirúrgico das FDU está longe de ter um consenso entre os especialistas. Acreditamos que os métodos menos invasivos e que privilegiam a estabilidade relativa são os mais adequados, pois complicações mais temidas são menos frequentes.

Humeral shaft fractures (HSF) represent 3 percent of fractures of the locomotor apparatus, the mid-third section of the shaft being the most commonly affected. In the majority of cases, it is treated by non-surgical methods, but surgical indications in HSF are increasingly being adopted. The diversity of opinions makes it difficult to reach a consensus regarding to the type of osteosynthesis, surgical technique, and quantity and quality of the synthesis materials to be used. It would appear that specialists are far from reaching a consensus as to the best method for the surgical treatment of HSF. We believe that less invasive methods, which favor relative stability, are the most appropriate methods, as the most feared complications are less frequent.
