RESUMO Objetivo: Analisar o perfil de pacientes com lesões de Lisfranc, as características das lesões e fraturas associadas. Métodos: Trata-se de uma análise retrospectiva com 42 pacientes com lesões de Lisfranc internados no Instituto de Ortopedia e Traumatologia do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo entre 2006 e 2010. O perfil dos pacientes, características das lesões, fraturas associadas, dados sobre o tratamento e complicações agudas foram analisados. Resultados: Nesta amostra, os homens foram mais afetados do que as mulheres, com uma proporção de 4,25:1. O mecanismo de trauma mais frequente foi acidente de carro, seguido por acidente com moto. O tipo de lesão mais frequente foi a lesão isolada tipo B de Quenu e Kuss, representando 50% dos casos. A fratura mais comumente encontrada foi a do segundo metatarso, com 16 casos, seguido pela fratura do osso cubóide. Entre os 42 casos estudados, sete foram fraturas expostas e 33 pacientes apresentaram fraturas associadas. O tempo médio entre o trauma e o tratamento definitivo foi de 6,7 dias. O tempo médio de permanência hospitalar foi de 13,8. Seis pacientes apresentaram complicações pós-operatórias agudas. Conclusão: As lesões de Lisfranc são mais comuns em homens submetidos a trauma automobilístico. A prevalência de fraturas associadas é um achado frequente e o tempo de permanência hospitalar pode ser prolongado. Nível de Evidência IV, Série de Casos:

ABSTRACT Objective: To analyze the characteristics of patients with Lisfranc injuries and their associated fractures . Methods: This is a retrospective analysis on 42 patients with Lisfranc injuries hospitalized at Instituto de Ortopedia e Traumatologia do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, between 2006 and 2010. Parameters on patient profile, risk factors, fracture characteristics, data on treatment and acute complications were analyzed . Results: Analysis of 42 cases showed that in our sample, men were more affected than women, with a ratio of 4.25:1. The most frequent trauma mechanism was car accident, followed by motorcycle accident. The most frequent type of injury was isolated lesion type B of Quenu and Kuss classification, representing 50% of cases. The most common fracture on the sample was the second metatarsal bone, with 16 cases, followed by cuboid bone fracture. Among the 42 cases, 17% had exposed fractures and 33 patients presented other associated fractures. The mean time elapsed between the trauma and definitive treatment was 6.7 days, while the mean length of hospital stay was 13.8 days. Six patients presented acute postoperative complications . Conclusion: Lisfranc injuries are more common in men undergoing automobile trauma. The prevalence of associated fractures is a frequent finding and the hospital stay may be longstanding. Level of Evidence IV, Case Series.

OBJECTIVES: To evaluate the epidemiology of ankle fractures surgically treated at the Instituto de Ortopedia e Traumatologia do Hospital das Clínicas da Universidade de São Paulo.METHODS: Medical records of patients admitted with foot and ankle fractures between 2006 and 2011 were revised. Seventy three ankle fractures that underwent surgical treatment were identified. The parameters analyzed included age, gender, injured side, AO and Gustilo & Anderson classification, associated injuries, exposure, need to urgent treatment, time to definitive treatment and early post-operative complications. Study design: retrospective epidemiological study.RESULTS: Male gender was predominant among subjects and the mean age was 27.5 years old. Thirty nine fractures resulted from traffic accidents and type B fracture according to AO classification was the most common. Twenty one were open fractures and 22 patients had associated injuries. The average time to definitive treatment was 6.5 days. Early post-operative complications were found in 21.3% of patients.CONCLUSIONS: Ankle fractures treated in a tertiary hospital of a large city in Brazil affect young people victims of high-energy accidents and present significant rates of associated injuries and post-operative complications.

OBJETIVO: Este artigo faz a avaliação retrospectiva clínica e radiológica das fraturas do odontóide de 20 pacientes atendidos no IOT-HCFMUSP, durante o período de 2004-2010. MÉTODOS: Foi realizado a estratificação destas fraturas segundo sua classificação (AO/Anderson e D'Alonzo), perfil epidemiológico, tipo de tratamento, tempo de consolidação e complicações. RESULTADOS: Observou-se maior número de casos da fratura do odontóide em pacientes do sexo masculino (4:1), com idade entre 3ª e 4ª década de vida (60%), vítimas de quedas de altura (60%) e acidentes automobilísticos (25%) como principais mecanismos de trauma, e 15% dos casos apresentaram-se com déficit neurológico. A fraturas do odontóide de maior prevalência foram as do tipo II (55%), seguidas pelas fraturas do tipo III (40%). Os tratamentos mais empregados nas fraturas do tipo II e III foram, respectivamente, o cirúrgico (73%) e conservador (87,5%). A consolidação ocorreu em até 16 semanas para 87,5% dos casos de tratamento cirúrgico e para 54,5% dos tratados conservadoramente. Não houve casos de pseudoartrose. CONCLUSÃO: O tratamento cirúrgico das fraturas do odontóide do tipo II apresentou resultados satisfatórios em relação ao tempo consolidação e baixa incidência de complicações, bem como o tratamento conservador destinado às fraturas do tipo III.Nivel de Evidência IV, série de casos.

OBJECTIVE: This article describes a clinical and radiologic retrospective analysis of odontoid fractures in20 patients accompanied byThe IOT-HCFMUSP,from 2004 to 2010. METHODS: These fractures were stratified according to their classification (AO/Anderson andD'Alonzo), epidemiologic profile, type of treatment, time to consolidation of the fracture, and complications. RESULTS: It was observed that there was a higher number of odontoid fractures in males (4:1), between the third and fourth decades of life (60%), and that the main causes of the trauma were falling from heights (60%) and car accidents (25%). Also, 15% of the cases presented neurological deficits. The most prevalent type of odontoid fracture was Type II (55%) followed by Type III (40%). The most prevalent type of treatment used for Type II and III fractures was surgical (73%) and non-surgical (87.5%), respectively. Consolidation of the fracture took place within 16 weeks in 87.5% of surgically treated cases, and in 54.5% of those treated non-surgically. No cases of pseudoarthrosis were found. CONCLUSION: The surgical treatment of Type II odontoid fractures showed satisfactory results in relation totime to consolidation of the fracture and low incidence of complications, as did the non-surgical treatment used for the Type III fractures. Level of Evidence: Level IV, case series.
