Abstract: | Distorted proximal femoral anatomy can pose a great technical challenge during total hip arthroplasty. Fifty-eight total hip arthroplasty were performed in 51 patients with proximal femoral deformity from 1998 to 2006. All hips except 2 were treated with cementless prosthesis. Twenty-three patients had a retained hardware that had to be removed. Nonprimary cementless components were used in 22 (25%) femurs. In 21 (23%) hips, osteotomy was required to properly fit the cementless stem in the femur. At the time of latest follow-up (4 years on average), functional scores showed significant improvement. Radiographically, all femoral components showed stable bone ingrowth except 2 hips (3.5%) with stable fibrous ingrowth and 1 hip (2%) with loosening. There were 2 (3.5%) revisions in 2 patients for periprosthetic fracture and femoral loosening. The mechanical failure rate was 9% (5 hips). Despite technical difficulties, cementless femoral reconstruction provides a reliable and durable result in patients with proximal femoral deformity. |
