CORAIL STEM FOR TOTAL HIP ARTHROPLASTY: 11 YEARS OF IMAGING FOLLOW-UP



Abstract

Purpose: The purpose of this study is to present our imaging results of Corail stem implant after 11 years of follow-up.

Material and Methods: 31 patients that underwent total hip arthroplasty between 1990–1996 in which Corail stem was implanted were included in this study.

The imaging parameters that were collected from patient X-rays were: radiolucent line, osteolysis, subsidence, cortical hypertrophy, cortical thinning, undersizing, distal pod, rounded calcar, cupping and sagging.

Results: Our of 31 patients, 21 were man and 10 were women, the mean age was 60.5 years (range 32–77y), 6 were bilateral, 3 patients had trochanteric osteotomy before surgery. The mean follow-up period was 8.2 years (range 5–11y).

No sign of loosening were observed in any patient, 23 stems were implanted in neutral position, 2 stems in valgus and 6 in varus position. In 15 patients stem was undersized. In 23 patients distal pod was observed, 19 patients had trochanteric osteopenia, in 10 patients cupping was noticed and in 6 patients cortical thinning was observed. Five patients showed proximal osteopenia and in 5 patients sagging of few millimeters was noticed during the first years after surgery. No radiolucent line, osteolysis, subsidence and cortical hypertrophy were observed up to 11 years follow-up.

Discussion: No signs of loosening were observed in all stems after 11 years of follow-up.

Conclusion: In our opinion Corail stem for THA is a very reliable implant.
