ABSTRACT
PURPOSE:
To evaluate the clinical and radiological outcomes following implantation of the Furlong hydroxyapatite ceramic-coated femoral stem in total hip arthroplasty.METHODS:
A longitudinal cohort of 116 consecutive patients (134 hips) was followed up prospectively. The follow-up period was at least 13 years (range, 13- 15 years). Clinical and radiological assessments were made using the Merle d'Aubigne and Postel score and Engh score for fixation and stability, respectively. Osteointegration was assessed radiographically by examining the bone implant interface using the method described by Gruen.RESULTS:
22 patients died during the study period and 6 were lost to follow-up. The respective mean Merle d'Aubigne and Postel scores for pain, range of movement, and ability to walk were 2.2, 2.8, and 2.4 preoperatively and 5.8, 4.8, and 5.4 postoperatively. Engh described satisfactory bony ongrowth as 10 points or more; the mean Engh score for fixation and stability was 24.7 (fixation=10, stability=14.7). One femoral stem was revised for a periprosthetic fracture caused by a fall, but none was revised for loosening. This gave a 99% survival at 13 years (95% confidence interval 94-100).CONCLUSION:
The long-term results of this hydroxyapatite ceramic-coated femoral prosthesis are very satisfactory.
