Analysis of Atrophy of Gluteus Maximus and Gluteus Medius in Legg-Calve-Perthes Disease

The cross-sectional area of the gluteus maximus and gluteus medius was measured on both sides in 10 patients with hemilateral Legg-Calve-Perthes disease (LCPD). We used CT scans at the level of the anterior superior apine of the iliac. The area ratio of the affected versus the unaffected side was calculated. The time of measurement from the onset of the disease was 2 months to 3 years and 8 months, and the total number of measurements was 32. We compared the averages between the non-weight bearing period when the patients were using wheelchairs and the period more than 12 months after the start of walking. The recovery from muscle atrophy was very slow and tended to require a very long time.
