The flying buttress acetabular bone-graft

Primary total hip arthroplasty is often required in the end-stage osteoarthritic hip secondary to hip dysplasia. At the time of surgery, a decision is made whether to bone-graft the dysplastic acetabulum to accommodate the acetabular component. A technique is described to augment the acetabular bone stock by adding a flying buttress autograft to the structural shelf graft.
