containment surgery
Surgical procedures designed to maintain the femoral head within the acetabulum during healing in Legg-Calvé-Perthes disease.
Full Definition
Containment surgery encompasses various surgical procedures performed in Legg-Calvé-Perthes disease to maintain the femoral head in proper position within the acetabulum during the healing phase. The principle is based on Salter's concept that a spherical femoral head will develop if it remains well-contained within the acetabulum during reossification. Common procedures include femoral varus derotation osteotomy, Salter innominate osteotomy, shelf procedures, and combined procedures. The goal is to improve coverage of the femoral head, redirect forces across the hip joint, and promote spherical remodeling. Timing and procedure selection depend on patient age, disease stage, lateral pillar classification, and degree of containment loss.
Usage
Usage note: Specify the exact procedure performed; avoid using as a general term for all Perthes surgeries.
