O1373 COMPUTER AIDED DESIGN -COMPUTER AIDED MANUFACTURE IN REVISION TOTAL HIP REPLACEMENT A TEN YEAR CLINICAL REVIEW



Abstract

Aims: The objective of this study was to clinically assess the outcome of CADCAM femoral components in the revision hip replacement. Methods: Between 1991 and 2000, 125 revision total hip replacements using CAD-CAM femoral components were performed. Clinical assessment was performed using the Harris Hip score, by direct patient consultation, and telephone or postal questionnaire. Survivorship was defined as the requirement for revision. Results: The patients were reviewed at a mean of 5.2 yrs (1 to 10)

The mean Harris hip score increased from 44 points (range, 27 to 71 points) preoperatively to 71 points (range, 21 to 98 points) at the time of the most recent follow-up. 9 patients required subsequent revision; 4 for aseptic loosening, 1 for septic loosening and 4 for fracture of the femoral component. Conclusions: CAD-CAM technology provides a viable alternative to the challenge of revision hip surgery, with results comparable to other cementless techniques.
