The purpose of the study was to evaluate the S-LOCK® system for total hip arthroplasty (THA) in patients with severe osteoporosis. The stems we used had a porous coating on the proximal half. All were fixed with interlocking screws. Eight patients (10 hips) underwent THA with the S-LOCK® system between June 2002 and July 2004. There were 2 men (2 hips) and 6 women (8 hips) whose mean age at operation was 53.4 years. The cases included osteoarthritis (1 hip in 1 patient), idiopathic osteonecrosis of the femoral head (3 hips in 3 patients), and rheumatoid arthritis (4 hips in 2 patients). A stovepipe-like canal appeared on radiographs in all cases. The mean follow-up period was 12.9 months (range 4 to 25 months). Japanese Orthopedic Association scores increased from 35 to 78 points. There were no indications of thigh pain or loosening in any of the cases.
