Long-term prognosis after Legg-Calvé-Perthes disease (LCPD) depends on the severity of residual hip deformities including a nonspherical femoral head, a short and wide femoral neck, a high riding greater trochanter, and secondary changes in the acetabulum. Hip deformity after healed LCPD may lead to abnormal hip mechanics including femoroacetabular impingement and hip instability secondary to acetabular dysplasia. The surgical dislocation approach has recently been applied to LCPD hip deformity with encouraging short-term results. This approach allows complete dynamic evaluation of the hip joint, identification, and correction of the most common residual deformities. The purpose of this paper is to describe the application of the surgical hip dislocation approach to LCPD deformity and to evaluate the current available literature on the results of this approach to the healed LCPD hip.
Legg-Calvé-Perthes病（LCPD）后的长期预后取决于残留髋关节畸形的严重程度，包括股骨头非球形、股骨颈短而宽、大转子高位以及髋臼的继发性改变。LCPD愈合后的髋关节畸形可能导致异常的髋关节力学，包括股骨髋臼撞击和髋臼发育不良继发的髋关节不稳定。手术脱位方法最近已应用于LCPD髋关节畸形，取得了令人鼓舞的短期效果。这种方法允许对髋关节进行完整的动态评估、识别并纠正最常见的残留畸形。本文的目的是描述手术髋关节脱位方法在LCPD畸形中的应用，并评估目前关于该方法治疗LCPD愈合髋关节结果的现有文献。
