Pelvic osteotomies are used for hip preservation in children and young adults to improve femoral head coverage and stabilize the hip joint. Redirectional osteotomies aim to reduce the overall volume and redirect the acetabulum. These include Salter, Pemberton, Dega, and San Diego osteotomies. Reorientation osteotomies aim to reorient the acetabulum and include periacetabular and triple osteotomies. Salvage osteotomies aim to enlarge the acetabulum and medialize the hip center. These include shelf and Chiari osteotomies. The standard anterior approach and surgical technique for the eight pelvic osteotomies used by hip preservation surgeons are described along with each osteotomy's history, indications, and outcomes.
