Does lateral shelf acetabuloplasty improve radiographic containment indices in patients with Legg-Calvé-Perthes disease?
Lateral shelf acetabuloplasty effectively improves radiographic containment of the femoral head in Legg-Calvé-Perthes disease.
Should not yet change practice in Legg-Calvé-Perthes disease; leaves open whether improved containment affects long-term outcomes.
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.

Bursal et al. (2004) conducted an observational in Legg-Calvé-Perthes disease (n=18). Shelf acetabuloplasty was evaluated on Acetabulum-head index and center-edge angle for containment. Shelf acetabuloplasty improved the acetabulum-head index and center-edge angle for containment in 18 patients (19 hips) with Legg-Calvé-Perthes disease.
