Hip disorders are the second most common musculoskeletal abnormality seen in children with cerebral palsy, affecting nearly 1 in 3. The goal of surgical intervention is to provide a mobile, located, and painless hip. Reconstructive procedures are indicated for children with migration percentages of >40%. Reconstructive procedures typically result in a long-term satisfactory outcome, although recurrence is seen particularly in nonambulatory children and when the reconstruction is performed earlier than 6 years of age. Salvage procedures are performed when reconstructive procedures are no longer an option and degenerative changes have occurred. They include proximal femoral valgus osteotomy, proximal femoral resection, and hip arthroplasty.
