Evaluating the effectiveness of interventions targeting only the acetabular side in the surgical treatment of Legg-Calve-Perthes disease

OBJECTIVE: This study aims to show the effectiveness of only acetabular-side surgeries for hips affected by Legg-Calve-Perthes disease.PATIENTS AND METHODS: Twelve patients who underwent two different acetabular osteot-omies -pembersal osteotomy and triple osteot-omy - were evaluated retrospectively. Clinically, patients were examined for hip range of motion, flexion contracture, and hip extensor and abduc-tor strength; the results were evaluated using the Harris hip score. Radiologically, the hips were as-sessed according to three different radiological parameters: lateral center edge angle, acetabular width, and acetabular head index at the preoper-ative, early postoperative, and last follow-up pe-riods. The hips were classified according to Her-ring classification preoperatively and according to Stulberg classification at the last follow-up.RESULTS: Statistically significant improve-ment was observed in patients both clinically and radiologically. It was observed that pember-sal osteotomy significantly corrected the lateral center edge angle better than triple osteotomy while also correcting the other two radiological parameters, but no statistically significant dif-ference was observed between these methods.CONCLUSIONS: Only acetabular-side surger-ies are effective and safe methods that do not require femoral intervention for hips affected by Legg-Calve-Perthes disease and that do not show significant complications.

Automated summary

This study investigated the effectiveness of only acetabular-side surgeries for treating hips affected by Legg-Calve-Perthes disease. Twelve patients who underwent different acetabular osteotomies were evaluated. The results showed significant improvements in both clinical and radiological evaluations. Pembersal osteotomy corrected the lateral center edge angle better than triple osteotomy, but no significant difference was observed between the two methods.
