The role of proximal femoral valgus osteotomy in Legg-Calvé-Perthes disease.

Proximal femoral valgus osteotomy for Legg-Calvé-Perthes disease was evaluated at an average 5 years postoperatively in 31 consecutive patients. The indications for osteotomy were hinge abduction and pain. The Iowa hip scores at follow-up for 21 patients averaged 93 points. Combined clinical and radiographic review for these patients yielded 6 (29%) excellent, 7 (33%) good, 5 (24%) fair, and 3 (14%) poor results. The 10 remaining patients had good pain relief and were satisfied but were unable to return for hip scale evaluation.
