Legg-Calvé-Perthes disease (LPD) is a childhood hip disorder that results in infarction of the bony epiphysis of the femoral head. LPD represents idiopathic avascular necrosis of the femoral head. The disease is bilateral in 10-20% of patients and usually affects children aged 4-8 years. When both hips are involved, they are usually affected successively, not simultaneously. A family history is present in 6% of patients. In adults, the corresponding condition is termed Chandler disease.
