Long-term results of a hydoxyapatite coated (JRI Furlong) total hip replacement femoral stem: A 15-21 year follow up
The medium term results of the JRI Furlong Total hip replacement have been very impressive to date. We report the longest prospective series to date of a hydroxyapatite coated femoral prosthesis (Joint Replacement Instrumentation limited, London, UK) at 15–21 years follow up. We describe the long term clinical and radiological femoral stem survival of 331 consecutive JRI Furlong Hydroxyapatite coated total hip replacements in 291 patients at an average follow-up of 17.5 years (15 – 21 year). Two patients (0.6%) were lost to follow-up over the 21 years of the study period. Using revision of the femoral stem for any reason as an endpoint, we report a stem survival of 97.4 % (81.0 to 99.5). Using Aseptic loosening as an endpoint, stem survival was 100%.

The average Merle, D’Aubine & Postel scores recorded for the patients was 5.63/6 for Pain, 5.42/6 for mobility and 4.50/6 for function. There were no cases of anterior thigh pain relating to the uncemented femoral stem.

These results compare favourably with the best long term survival of cemented or uncemented femoral stems used in total hip replacements

Abstract

The medium term results of the JRI Furlong Total hip replacement have been very impressive to date. We report the longest prospective series to date of a hydroxyapatite coated femoral prosthesis (Joint Replacement Instrumentation limited, London, UK) at 15–21 years follow up. We describe the long term clinical and radiological femoral stem survival of 331 consecutive JRI Furlong Hydroxyapatite coated total hip replacements in 291 patients at an average follow-up of 17.5 years (15 – 21 year). Two patients (0.6%) were lost to follow-up over the 21 years of the study period. Using revision of the femoral stem for any reason as an endpoint, we report a stem survival of 97.4 % (81.0 to 99.5). Using Aseptic loosening as an endpoint, stem survival was 100%.

The average Merle, D’Aubine & Postel scores recorded for the patients was 5.63/6 for Pain, 5.42/6 for mobility and 4.50/6 for function. There were no cases of anterior thigh pain relating to the uncemented femoral stem.

These results compare favourably with the best long term survival of cemented or uncemented femoral stems used in total hip replacements
