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

ResumoObjetivorevisar os prontuários de 19 pacientes com diagnóstico de amioplasia, submetidos à osteotomia extensora percutânea de fêmur distal, para correção de deformidade fixa em flexão dos joelhos.Métodosanalisamos 37 osteotomias em 35 joelhos com média de deformidade fixa inicial média em flexão dos joelhos de 33,8°, todos submetidos à osteotomia percutânea extensora do fêmur distal e acompanhados em média de 73,7 meses.Resultadosobservamos recidiva da deformidade em 29 osteotomias, ou seja, 78,4% delas. A velocidade média de recidiva da deformidade foi de 0,69°/mês.Conclusãoa osteotomia extensora percutânea do fêmur distal forneceu correção suficiente da deformidade fixa em flexão dos joelhos na amioplasia, porém apresentou significativo grau de recidiva nos pacientes analisados.AbstractObjectiveto 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.Methodswe analyzed 37 osteotomy procedures on 35 knees that presented an initial deformity in which the knees were fixed in flexion at 33.8°.

Analysis on the results from percutaneous extensor osteotomy of the distal femur in patients with amyoplasia

Objective: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 whom 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 period 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
