Complex Acetabular Deficiency: Rebuilding the Skeleton

Revising the acetabular component in revision hip surgery may be quite complex because of loss of bone stock. The goals for acetabular revision are to restore the anatomy and achieve stable fixation for the new acetabular component. The existing bone stock and the type of bone defect are the major parameters in selecting a reconstruction option. In younger, high-demand patients for whom another revision is likely during their lifetime, restoration of bone stock by grafting at least makes another revision possible. In the elderly, relatively lower-demand patient, a stable acetabular reconstruction can be achieved by using new porous metals that can provide stable fixation at the correct anatomic level but with less of an emphasis on bone grafting.
