Highlights
Juvenile osteochodrosis of the femoral head (Legg-Calvé-Perthes disease) and avascular bone necrosis have been studied extensively for at least 100 years there are still controversies in etiology of the disease and optimal treatment of the condition [1–8]
Changes in gluteal muscles of patients with LeggCalvé-Perthes disease and avascular bone necrosis were characterized by general manifestations taking into consideration general etiological factors and clinical features
Decreased length of m. gluteus medius and m. gluteus minimus was observed in coronal MR images
Summary
Juvenile osteochodrosis of the femoral head (Legg-Calvé-Perthes disease) and avascular bone necrosis have been studied extensively for at least 100 years there are still controversies in etiology of the disease and optimal treatment of the condition [1–8]. Changes in the femoral head in Legg-Calvé-Perthes disease and avascular necrosis evaluated with imaging modalities (MSCT, MRI, US) are well described at different stages of the disease [9–11]. There are studies reporting of normal picture of the soft tissues surrounding the hip joint and the osseous components examined with MRI and MSCT [18, 19]. There have been no studies that would quantitavely examine gluteal muscles in pediatric hip pathologies using MRI. There are studies describing hypotrophy or atrophy of gluteal or thigh muscles in Perthes disease [12, 22–24]
