Análise de resultados da osteotomia extensora percutanea de fêmur distal em pacientes com amioplasia

摘要

ResumoObjetivo revisar os prontuários de 19 pacientes com diagnóstico de amioplasia, submetidos à osteotomia extensora percutanea de fêmur distal, para corre??o de deformidade fixa em flex?o dos joelhos. Métodos analisamos 37 osteotomias em 35 joelhos com média de deformidade fixa inicial média em flex?o dos joelhos de 33,8°, todos submetidos à osteotomia percutanea extensora do fêmur distal e acompanhados em média de 73,7 meses. Resultados observamos recidiva da deformidade em 29 osteotomias, ou seja, 78,4% delas. A velocidade média de recidiva da deformidade foi de 0,69°/mês. Conclus?o a osteotomia extensora percutanea do fêmur distal forneceu corre??o suficiente da deformidade fixa em flex?o dos joelhos na amioplasia, porém apresentou significativo grau de recidiva nos pacientes analisados. AbstractObjective to review the medical files of 19 patients with a diagnosis of amyoplasia, who underwent percutaneous extensor osteotomy of the distal femur to correct deformities in which the knees were fixed in flexion. Methods we analyzed 37 osteotomy procedures on 35 knees that presented an initial deformity in which the knees were fixed in flexion at 33.8°. All of these knees underwent percutaneous extensor osteotomy of the distal femur and were followed up for a mean of 73.7 months. Results we observed recurrence of the deformity in 29 osteotomy cases, i.e. in 78.4% of them. The mean recurrence velocity of the deformity was 0.69°/month. Conclusion percutaneous extensor osteotomy of the distal femur provided sufficient correction of deformities in which the knee was fixed in flexion in these amyoplasia cases, but there was a significant degree of recurrence among the patients analyzed.
