Abstract

PURPOSE: Surface finishing of a cemented femoral stem is a subject of controversy even though contemporary cementing techniques have improved results. Versys Heritage femoral stem was used with a contemporary cementing technique to determine the outcome of using a polished surface.
MATERIALS AND METHODS
Between October 2000 and August 2003, 131 primary hybrid hip arthroplasty procedures were performed in 117 patients. The mean age at the time of the index arthroplasty was 52 years and 9 months (24-78 years). The average follow up period was 49 months (range, 24-71 months). All the hips were evaluated clinically by the Harris hip score and radiologically by the cement grade, osteolysis as well as stress shielding.
RESULTS
At the final follow up, the Harris hip score for all patients had improved from preoperative 59.1 (range, 17-91) to post operative 92.8 (range, 78-100). The cement grade was measured using Barrack's method. Of 131 hips, 75, 54 and 2 were grade A, grade B and grade C1 at the final follow up, respectively. None of the hips showed a C2 or D grade. There was no evidence of aseptic loosening or osteolysis on the femoral side during follow up. 45% of stems showed grade 1 and 2 stress shielding according to Engh's criteria.
CONCLUSION
In this study, the Polished Versys Heritage femoral stem(R) showed excellent results at the short to mid term follow up period. However, a longer-term follow-up study will be needed to clarify the implications of the femoral prosthesis surface finish or design.
