Ten- to twelve-year follow-up of the furlong hydroxyapatite-coated femoral stem and threaded acetabular cup in patients younger than 65 years.

We reviewed 82 patients who had 92 primary Furlong uncemented hydroxyapatite (HA)-coated total hip replacements inserted between 1988 and 1992. All patients had the Furlong HA-coated stem and screw in acetabular cup with a 28-mm alumina oxide ceramic modular head. The mean age at the time of primary total hip arthroplasty was 54 years (range, 31-67 years). At 10 years, we reviewed 64 patients (72 total hip arthroplasties). Eight had died (10 total hip arthroplasties), 3 could not attend for follow-up, 2 were lost to follow-up, and 5 were revised (2 for infection and 3 for acetabular loosening and recurrent dislocation). We conclude that the Furlong HA-coated total hip replacement is a good prosthesis for patients younger than 65 years, with a cumulative survival rate of 94.29% at 10 to 12 years using revision as the end point.
