Abstract
The survivorship of the Corin femoral stem component for primary hip arthroplasty is described. The Corin Taper-Fit Femoral System was designed on the same biomechanical principles as the Exeter femoral stem but with an introducer designed to improve accuracy of insertion. Between 1995 and 1999, 246 Corin Taper-Fit stems were implanted in 222 patients. All procedures were performed in a Distrtict General Hospital. The Elite/Ogee acetabular component was used in all but 2 of the hips.
Seven patients were lost to follow-up during the period of this study and 68 patients (71 hips) died.
No femoral component was revised for aseptic loosening. Three hips were classified as failures of the acetabular component, two of these were for recurrent dislocation, and the other is not recorded. No hip was revised for deep infection. The ‘worst case’ scenario, including the patients lost to follow up, is a survival rate of 97% for the femoral component at 14years.
These results show that the medium term outcome for this implant, used in a district general hospital, are excellent. This supports other studies which show impressive medium term results with cemented tapered polished stems.
