Musculoskeletal injuries in motorcycle accidents

Study conducted in the city of São Paulo from January 2001 to July 2002 with the goal of analyzing the profiles of individuals involved in motorcycle accidents, evaluating the rider's profile, the circumstances of the accidents, injuries, and the use of protective gear. 387 patients needing only traumatic orthopedic treatment were found, between 16 and 44 years of age, of which 354 were males (91.0%). The most common mechanism of trauma involved a collision between the motorcycle and another vehicle (67.0%) at a speed between 12.5-37.5 mph (73.0%) involving less experienced riders (67.0%) between 21 and 24 years of age (45%), and in which 532 (53.9%) lower limb injuries occurred. Of the injuries, 393 (39.8%) were wounds, 314 (31.8%) were bruises and 212 (21.5%) were fractures [foot, 34 (16%); femur, 32 (15.1%); ankle, 27 (12.7%); tibia, 25 (11.8%)]. Recurring accidents were observed in 231 (60.0%) cases and only 6.0% of the riders were not using protective equipment. Increased speed showed a higher rate of fractures when the Mann-Whitney test was applied (p = 0.001). Research on mechanical and traffic engineering, in combination with supervision and awareness-raising of the population, should be considered the most effective methods of prevention.Estudo realizado no município de São Paulo entre janeiro de 2001 e julho de 2002 e tem como objetivo analisar o perfil do indivíduo envolvido em acidentes motociclísticos avaliando: o perfil do condutor, as circunstâncias dos acidentes, as lesões e o uso de equipamentos de segurança. Foram encontrados 387 pacientes sendo 354(91,0%) do sexo masculino, entre 16 e 44 anos e considerados os indivíduos que necessitaram somente do tratamento traumato-ortopédico. O mecanismo de trauma mais comum envolveu a colisão entre a moto com outro veículo (67,0%), numa velocidade entre 20-60km/h (73,0%), em pessoas com menor experiência (67,0%) na idade entre 21-24 anos (45,0%), nos quais 532 (53,9%) lesões ocorreram nos membros inferiores. Quanto ao tipo de lesão tivemos 393(39,8%) ferimentos, 314(31,8%) contusões e 212(21,5%) fraturas [ossos do pé 34(16%), fêmur 32(15,1%), tornozelo 27(12,7%), tíbia 25(11,8%)]. A reincidência foi observada em 231(60,0%) acidentes e somente 6,0% dos pacientes não usavam equipamentos de proteção.O aumento da velocidade relacionou-se à um índice maior de fraturas quando foi aplicado o teste de Mann-Whitney (p=0,001). Pesquisas de engenharia mecânica e de engenharia de tráfego, associadas à rigorosa fiscalização e conscientização da população, devem ser consideradas o método mais efetivo , que é o da prevenção.Universidade Federal de São Paulo (UNIFESP) Escola Paulista de Medicina Departamento de Ortopedia e TraumatologiaUNIFESP, EPM, Depto. de Ortopedia e TraumatologiaSciEL

A CT-based classification of prior ACL femoral tunnel location for planning revision ACL surgery

The purposes of this study are to describe an ACL femoral tunnel classification system for use in planning revision ACL reconstruction based on 3-D computed tomography (CT) reconstructions and to evaluate its inter- and intra-rater reliability.A femoral tunnel classification system was developed based on the location of the femoral tunnel relative to the lateral intercondylar ridge. the femoral tunnel was classified as Type I if it was located entirely below and posterior to the ridge as viewed from distally, Type II if it was slightly malpositioned (either vertically, anteriorly, or both), and Type III if it was significantly malpositioned. To evaluate the reproducibility of the classification system, CT scans of 27 knees were obtained from patients scheduled for revision ACL reconstruction, and 3-D reconstructions were created. Four views of the 3-D reconstruction of each femur were then obtained, and inter- and intra-observer reliability was determined following classification of the tunnels by eight observers.Twenty-five tunnels were classified as Type I (5 tunnels), Type II (9 tunnels), or type III (11 tunnels) by at least 5 of 8 observers, while insufficient agreement was noted to classify two tunnels. the interobserver reliability of tunnel classification as type I, II, or III yielded a kappa coefficient of 0.57, while intra-observer reliability yielded a kappa coefficient of 0.67. Subclassification of type II femoral tunnels into the subgroups anterior, vertical, and both was possible in four of the nine type II patients. the interobserver reliability of the complete classification system yielded a kappa coefficient of 0.50, while the intra-observer reliability yielded a kappa coefficient of 0.54.Classification of the location of ACL femoral tunnels utilizing 3-D reconstructions of CT data yields moderate to substantial inter- and intra-observer reliability.Diagnostic Level III.Ohio State Univ, Sch Med, Dept Orthopaed Surg, Columbus, OH 45631 USAUniversidade Federal de São Paulo, Dept Orthopaed & Traumatol, São Paulo, BrazilMinist Hlth, Dept Orthopaed Surg, Bandar Seri Begawan, BruneiHop Croix Rousse, Dept Orthopaed Surg, Ctr Albert Trillat, F-69317 Lyon, FranceUniversidade Federal de São Paulo, Dept Orthopaed & Traumatol, São Paulo, BrazilWeb of Scienc
