Surgical considerations and planning for acetabular and femoral deficiencies in revision hip replacement.

Cementless revision total hip arthroplasty provides a method for augmenting and restoring the remaining bone stock in a failed total hip arthroplasty. Careful preoperative planning, precise intraoperative technique and an adequate prosthetic inventory are required. Classification systems for bone deficiencies aid in planning grafting and prosthetic needs and in reviewing postoperative results. New cementless technology should provide even more satisfying results.
