Category: Furlong Clinical Results

From Conquest Hospital, Hastings, England

We describe the clinical and radiological outcome of 100 consecutive total hip replacements in 86 patients using the JRI Furlong hydroxyapatite-coated femoral component. The follow-up was 100% at a mean of ten years (9.0 to 12.0). All 54 living patients (62 hips) were examined annually. Their mean Merle d’ Aubigné score was 5.8 / 5.6 / 4.6. A total of 32 patients had died. Their notes at the last annual assessment recorded a similar outcome to that of the living patients. Radiographs showed no radiolucent lines around any femoral component and there were no signs of impending failure. One patient required exision arthroplasty, but the femoral component had been bonded satisfactorily. There have been no other revisions of femoral components. Our findings suggest that the hydroxyapatite coating gives a satisfactory prosthesis-bone interface which is preferable to any other system.

The 13 to 16 year results of the use of the JRI Furlong hydroxapatite coated femoral stem

From Conquest Hospital, Hastings

We present the results of the first 100 JRI Furlong HAC femoral stems (86 patients) implanted in out institution. One patient has undergone excision arthroplasty for suspected infection at which time the femoral component was found to be well bonded. No other femoral component has been revised or has evidence of loosening, The latest mean Merle D’Aubigné & Postel scores are 5.8 / 5.8 / 4.9 (mean 13 years 11 months follow up). In this series, the overall survival rate is 99% with no cases of aseptic loosening. This hydroxyapatite coated femoral stem continues to have outstanding survival figures in the long term.
