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.
