| Popis: | Cementless total hip replacement has been advocated for patients with osteonecrosis of the femoral head. This study examined the outcome of the femoral stem of four generations of an uncemented, proximally porous-coated, chrome-cobalt total hip prosthesis. There were 158 cases in 141 osteonecrosis patients (74 men, 67 women) who had a mean age of 46 years (range, 17-83 years). The mean follow-up was 103 months (range, 20-235 months). The femoral components of 144 cases were not revised and had a mean Harris hip score of 84 (+/-15) at final follow-up. Of the 14 revisions (8.9%), the primary reasons for revision were loosening or significant osteolysis. There were one infection and one chronic dislocation. Proximally porous-coated, anatomic, press-fit stems provide excellent long-term results in patients with osteonecrosis of the femoral head. |
