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, 31-67years). At 10 years, we reviewed 64patients (72 total hip arthroplasties). Eight had died (10 total hip arthroplasties), 3could 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.
