Combined osteotomy as a salvage procedure for severe Legg-Calvé-Perthes disease
1Orthopaedic Physicians, Inc., Seattle, Washington.
Insights
Combined osteotomy surgery effectively treated severe Legg-Calvé-Perthes disease in children, improving hip joint function and shape. This salvage procedure demonstrated positive clinical and radiographic outcomes after an average 8-year follow-up.
Area of Science:
- Pediatric Orthopedics
- Surgical Innovation
- Hip Dysplasia Research
Background:
- Severe Legg-Calvé-Perthes disease presents significant challenges in pediatric hip treatment.
- Standard treatments may not always yield optimal long-term outcomes for advanced disease stages.
- Head-at-risk signs indicate a poorer prognosis in Legg-Calvé-Perthes disease.
Purpose of the Study:
- To evaluate the efficacy of combined Salter innominate and varus femoral osteotomies.
- To assess clinical and radiographic results in patients with severe Legg-Calvé-Perthes disease.
- To determine the long-term effectiveness of this combined surgical approach as a salvage procedure.
Main Methods:
- Retrospective analysis of 14 pediatric patients with severe Legg-Calvé-Perthes disease (Catterall class III/IV).
- Procedures included combined Salter innominate and varus femoral osteotomies.
- Mean follow-up duration was 8 years, with clinical assessment and radiographic evaluation (epiphyseal index, congruency).
Main Results:
- Eleven of 14 patients achieved good clinical results.
- Radiographs showed progressive spherical remodeling of the femoral head.
- 13 of 14 hips had an epiphyseal extrusion index <20% at follow-up, with 7 hips demonstrating spherical congruency.
Conclusions:
- Combined osteotomy is a safe and effective salvage procedure for severe Legg-Calvé-Perthes disease.
- The technique promotes favorable femoral head remodeling and congruency.
- This approach offers a viable solution for complex pediatric hip conditions.
Abstract:
Combined Salter innominate and varus femoral osteotomies were performed on 14 patients with severe Legg-Calvé-Perthes disease. The mean patient age was 8 years 4 months. Nine hips were Catterall class III, five class IV, and all had three or more head-at-risk signs. The average preoperative epiphyseal index was 30%. Mean follow-up was 8 years. Eleven of 14 patients had a good clinical result, and radiographs showed progressive spherical remodeling of the femoral head. Seven hips demonstrated spherical congruency at follow-up. The epiphyseal extrusion index at follow-up was less than 20% in 13 of 14 hips. We conclude that combined osteotomy is a safe and effective salvage procedure in severe Legg-Calvé-Perthes disease.
