Between 1986 and 1991 we implanted 331 consecutive Furlong hydroxyapatite-coated
femoral components of a total hip replacement in 291 patients. A cemented
acetabular prosthesis was used in 217 hips and a hydroxyapatite-coated component
in 114. We describe the long-term clinical and radiological survival of the
femoral component at a mean follow-up of 17.5 years (15 to 21). Only two
patients (0.68%) were lost to follow-up. With revision of the femoral component
for any reason as the endpoint, the survival at a mean of 17 years was 97.4%
(95% confidence interval 94.1 to 99.5), and with revision for aseptic loosening
as the endpoint it was 100%. The survival at a maximum of 21 years with revision
of the femoral component for any reason as the endpoint was 97.4% (95%
confidence interval 81.0 or 99.5). These results compare favourably with the
best long-term results of cemented or uncemented femoral components used in
total hip replacement.
