This document defines Legg-Calvé-Perthes disease as a condition that disrupts the blood supply to the femoral head, causing bone death. It progresses through stages of bone resorption and remodeling. Treatment aims to restore mobility and prevent deformity through symptomatic care, bracing, or surgery depending on the child's age and stage of disease. Surgical options include osteotomies and shelf procedures to contain the femoral head within the acetabulum.
