Legg-Calvé-Perthes disease

Full Definition

Legg-Calvé-Perthes disease is a childhood condition characterized by temporary loss of blood supply to the femoral head, leading to avascular necrosis and subsequent remodeling. Named after three physicians who described it independently, the disease typically affects children aged 4-8 years, with a 4:1 male predominance. The condition progresses through four stages: initial necrosis, fragmentation, reossification, and remodeling. Treatment focuses on maintaining hip mobility and containing the femoral head within the acetabulum during the healing process.
