Lateral shelf acetabuloplasty Legg-Calve-Perthes disease

Although head containment is extremely important for the development of the acetabulum and femoral head, there are debates about conservative and surgical treatment. Shelf acetabuloplasty is an effective means of treatment as regards the coverage of the femoral head within the acetabulum, which is the most important issue for the normal development of the hip joint. Nineteen hips of 18 patients were evaluated radiographically using the acetabulum-head index of Heyman and Herndon and the center-edge angle for containment. It was shown that postoperatively both indices improve to increase the containment, thus demonstrating the effectiveness of shelf acetabuloplasty. (c) 2004 Lippincott Williams & Wilkins.
