Pfannenwechsel bei größeren Defekten mit Antiprotrusionsringen

Abstract

30 acetabular cup revisions with a new Burch-Schneider ring underwent prospective clinical and radiologic examination and were analyzed for an average follow-up of 20.6+/-7.8 months (3-36 months). The Harris Hip Score increased from preoperative 46.6 to postoperative 75.9 points. A loosening of the cage was not recorded.
