Pediatric Hip and Acetabulum

Hip preservation surgery is performed in young patients with complex hip disorders using traditional radiographs and fluoroscopy. Three-dimensional (3D) computer modeling and printing offer distinct advantages over radiographs in planning complex osteotomies of the femur and acetabulum. For patients with hip dysplasia, slipped capital femoral epiphysis (SCFE), and Legg-Calve-Perthes, the technology allows preoperative 3D simulation of patient-specific correction and dynamic motion to assess for joint congruency and impingement before and after an osteotomy. Once the osteotomy plan is finalized with the computer modeling, a 3D model is printed which provides a tangible intraoperative template for use in surgery. Case examples are presented in this chapter which demonstrate its utility in hip preservation surgery.
