Pelvic Osteotomy (Salter et al.)

Acetabular reorientation can be considered by a specialist to improve stability when pediatric femoral head necrosis (Perthes disease) presents with insufficient acetabular coverage, decreased containment, or a tendency to displace, accompanied by pain and gait abnormalities, and when conservative treatment has limited effectiveness. The decision is influenced by factors such as age, disease stage, joint range of motion, imaging assessment, and whether combined femoral osteotomy is needed.
