INTRODUCTION

Since July 2008 we are experimenting a new cup with iliac screw fixation, developed on the idea of Ring and Mc Minn. Iliac fixation is permitted by a polar screw of large diameter, coated by HA, which allows a compression to bone and a firm primary stability. Moreover it's possible to increase primary stability with further smaller peripherals screws. We present this new cup and report the preliminary results.

MATERIALS AND METHOD

Since July 2008 to April 2010, 51 cups were implanted. The diagnosis was aseptic loosening in 36 cases, septic loosening treated by two-stage revision in 7, hip congenital dislocation in 5, one case of post-traumatic osteoarthritis, one case of instability due to cup malposition and a case was an outcome of Girdlestone resection arthroplasty. Mean age was of 66 years (31-90).
