Abstract
OBJETIVO: Avaliar a eficácia do fixador externo não transfixante como tratamento provisório das fraturas expostas Gustilo e Anderson graus I e II. MÉTODOS: Em estudo prospectivo, 36 fraturas expostas da diáfise da tíbia foram tratadas seqüencialmente com fixador não transfixante seguido por haste intramedular maciça bloqueada não fresada. A média de idade foi de 28 anos e 88,9% dos pacientes eram do sexo masculino. O mecanismo de trauma foi: acidente motociclístico em 47,1%, atropelamento em 36,1%. Entre os pacientes, nove (25,0%) apresentaram lesões associadas. Segundo a classificação AO, 12 pacientes (33,3%) haviam sofrido fraturas do tipo A, 18 (50,0%) do tipo B e seis (16,6%) fraturas tipo C. Segundo a classificação de Gustilo e Anderson, 13 pacientes (36,1%) eram portadores de fraturas expostas grau I e 23 (63,9%), de fraturas grau II. O tempo médio de fixação externa foi de seis dias, variando de três a 22 dias. RESULTADOS: Entre os pacientes, 32 evoluíram satisfatoriamente. As complicações relacionadas ao fixador existiram em quatro pacientes: em três houve impossibilidade de conversão com o fixador instalado e em um ocorreu neurapraxia do fibular superficial. CONCLUSÃO: O fixador externo não transfixante é útil como fixação provisória das fraturas expostas da diáfise da tíbia quando se visa a conversão para osteossíntese intramedular.
OBJECTIVE: To evaluate the effectiveness of the pinless external fixator for the provisional treatment of Gustilo and Anderson grade I and II open fractures. METHODS: In a prospective study, 36 open diaphyseal fractures of the tibia were sequentially treated with a pinless fixator followed by massive, blocked, non-edged intramedullary nail. Mean age was 28 years, and 88.9% of the patients were male. The mechanism of trauma was: motorcycle accident in 47.1%, being run over by vehicle in 36.1%. Among the patients, 9 (25.0%) had associated lesions. According to the AO classification, 12 patients (33.3%) had suffered type A fractures, 18 patients (50.0%), type B fractures, and 6 patients (16.6%), type C fractures. According to the Gustilo and Anderson classification, 13 patients (36.1%) had grade I opened fractures, and 23 (63.9%) had grade II fractures. The mean time of external fixation was six days, ranging from 3 to 22 days. RESULTS: 32 patients had a satisfactory evolution. Fixator-related complications were seen in four patients: in three, the installed fixator could not be converted, and one had surface fibular neurapraxia. CONCLUSION: The pinless external fixation helps as provisional fixation of open diaphyseal fractures of the tibial when the intention is to later convert to intramedullary osteosynthesis.
