We describe the clinical and radiological results of 38 total hip replacements (THR) using the JRI Furlong hydroxyapatite-ceramic (HAC) – coated femoral component in patients younger than 50 years. The mean age at the time of operation was 42 years and the mean length of follow-up was ten years. All patients receiving a Furlong HAC THR were entered into the study regardless of the primary pathology including patients who had undergone previous hip surgery.

The mean Harris hip sc ore improved from 44 before operation to 92 at the last post-operative review. After 12 years the cumulative survival for the stem was 100%. No femoral component was revised. Our results show that the Furlong HAC implant gives excellent long-term results in young patients with high demands.
