What is Legg-Calve-Perthes disease (LCPD)?

Legg-Calvé-Perthes disease is an avascular necrosis of the femoral head, usually seen in young boys aged 3-12. Avascular necrosis is diminished blood flow to part of a bone. Nutrients are unable to nourish the bone, which causes it to become structurally weak and break down. Due to structural changes in the femoral head, the hip joint becomes weak and loses function. Later stages of this disease can result in arthritis, deformity, and permanent functional loss.
