Triple pelvic osteotomy in Legg-Calvé-Perthes disease using a single anterolateral incision.

Pelvic osteotomy has a small role to play in the management of Legg-Calvé-Perthes disease. Residual acetabular dysplasia or incongruity can be corrected by rotational acetabuloplasty. In skeletally immature patients this can be performed by complete or incomplete innominate osteotomies. We present the case of a 12-year-old child with residual acetabular dysplasia, resulting from Legg-Calvé-Perthes disease, which was treated by a triple pelvic osteotomy performed by a small single anterolateral incision.
