Equinus deformity during tibial lengthening with ankle orthoses for equalization of leg-length discrepancies

摘要

Background Although it is known that equinus deformity develops at a high rate during tibial lengthening, the efficacy of ankle orthoses for preventing equinus deformity and the etiology of equinus deformity remain unknown. The purpose of this study was to clarify the incidence and causes of equinus deformity in tibial lengthening with ankle orthoses worn for 16 h a day.
