Avascular necrosis of the femoral head in a child is known as?

Recognizing Legg-Calvé-Perthes disease, the avascular necrosis of the femoral head in a child, is about understanding how temporary loss of blood supply to the growing head of the thigh bone affects kids. In this condition, the blood flow to the capital femoral epiphysis is interrupted, leading to bone death and a process of collapse and later reossification as circulation returns. Children commonly affected are around ages 4 to 8, often with a painless or mildly painful limp and limited hip motion. X-ray findings evolve from early changes such as sclerosis or slight irregularity to eventual flattening and fragmentation of the femoral head, which may later reossify as healing occurs. This differs from Slipped Capital Femoral Epiphysis, which occurs in adolescents and involves downward slippage of the femoral head through the growth plate rather than true avascular necrosis. Freiberg infarction is avascular necrosis of a metatarsal head in the foot, usually the second metatarsal, causing forefoot pain, not hip symptoms. Koenig disease refers to avascular necrosis of the navicular bone in the foot.
