Prevention of Hip Dislocation after Total Hip Arthroplasty

Abstract

We performed THA on 48 patients with osteoarthritis using a cup insert with 20 degrees hood and 26 mm femoral head, to prevent hip dislocation. We turned posterior the cup insert about 60 degrees on the plane on which the cup was placed. Good results were obtained, and the average JOA score was 82, up 35 points. No dislocation occurred. This method may be effective for preventing hip dislocation after THA.
