Legg-Calve-Perthes Disease: Imaging Evaluation and Management.
Legg-Calve-Perthes disease reflects avascular necrosis of the proximal femoral epiphysis and growth plate in children age 4 to 8 years typically. The most likely etiology is vascular deficiency to the epiphysis and growth plate. The pathologic stages consist of necrosis, resorption, reossification, and remodeling. Radiologic findings reflect the pathologic stages. Containment of the femoral head with the acetabulum is the most important component of treatment, with preservation of range of motion also indicated in most patients. Surgical options for treatment include varus or valgus femoral osteotomy, innominate osteotomy, and shelf arthroplasty.
