The Furlong hydroxyapatite-coated femoral prosthesis. A 4- to 7-year follow-up study.

We report the clinical and radiograph outcome of 77 Furlong hydroxyapatite fully coated femoral prosthesis in 71 patients undergoing primary total hip replacement, with mean follow-up of 65 months (range 48-82 months). The patients' average age at surgery was 55 years. The clinical results, as determined by Harris hip score, were excellent or good for 84% of the hips. Thigh pain which was not disturbing was present in 9% of the hips. No femoral component had been revised for aseptic loosening, and none were considered loose radiographically at the time of final follow-up evaluation. Serial radiographs revealed an excellent quality of bone around the prostheses, with positive evidence of bone ingrowth and no signs of impending failure.
