Legg Calve Perthes Disease

Legg-Calvé-Perthes disease is a rare disease of the hip that afflicts approximately 1 in 1200 children. Of those children, only about one in four are girls. About 5% of all diagnosed develop the disease in both hips (bilaterally). Most of these children are very active and often very athletic. The age of diagnosis is usually between 2 and 12 years old, with the average age of 6. Legg-Calve'-Perthes children tend to be of shorter stature due to delayed bone age. The purpose of this pamphlet is to provide you with more information to help you understand this condition and some of the treatments.
