Legg-Calvé-Perthes Disease is a childhood condition that affects the hip joint. It occurs when the blood supply to the femoral head, the ball part of the hip joint, is temporarily disrupted. This leads to the death of bone cells, causing the femoral head to become weak and misshapen. Symptoms often include hip pain, limping, and reduced range of motion. The exact cause of Legg-Calvé-Perthes Disease is not fully understood, but it typically affects children between the ages of 4 and 10. Treatment may involve rest, physical therapy, or in some cases, surgery to improve hip function and prevent long-term complications.
