Abstract
A retrospective review was conducted to evaluate the mid-termresults (8.5 years follow-up) of the Varsys ET STETM (Zimmer, Warsaw, Indiana, USA. From 1995 to 2000, 225 total hip arthroplasty (THA) were performed using this device. All patients were evaluated clinically by the Harris Hip Score, and radiographically. The Hip Score increased fron 54 preoperatively to 97 point postoperatively. The stem displayed a varus alignment between 5° and 10° in 17cases without any clinical consequences (HHS 96.8). We recorded one case of septic loosening and one case of aseptic loosening. The stability of the stem was radiographically evaluated according to Engh's criteria, confirming bone ongrowth in all other cases.
