title: Efficacy of cementless total hip arthroplasty in patients on long-term hemodialysis.
abstract: We retrospectively reviewed 11 hip arthroplasties in 7 patients receiving long-term (15 years) hemodialysis for chronic renal failure. Osteonecrosis of the femoral head, osteoarthritis, and amyloid arthropathies were treated by total hip arthroplasty (THA) or bipolar hemiarthroplasty (BHA) using cementless anatomic medullary locking stem. The average follow-up period was 8 years and 3 months (range, 3-13 years). The D'Aubigne and Postel hip score was restored to 14.5 postoperatively from 7.7 preoperatively. All femoral cementless components achieved bone-ingrown fixation. Although 1 BHA resulted in central migration, there was no loosening of the cementless acetabular component. We are encouraged by the predictable long-term stability of the bone-implant interface achieved by cementless fixation with an extensively coated implant. Cementless THA remains a useful treatment option for patients on long-term hemodialysis.
