A retrospective review was conducted to evaluate the mid-term results (8.5 years follow-up) of the Versys ET stem (Zimmer, Warsaw, Indiana, USA). From 1995 to 2000, 225 total hip arthroplasties (THA) were performed using this device. All patients were evaluated clinically by the Harris Hip Score, and radiographically. The Hip Score increased from 54 preoperatively to 97 points postoperatively. The stem displayed a varus alignment between 5 degrees and 10 degrees in 17 cases 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.
进行了一项回顾性研究，以评估Versys ET柄（美国印第安纳州华沙市的齐默公司生产）的中期结果（随访8.5年）。1995年至2000年期间，使用该装置进行了225例全髋关节置换术（THA）。所有患者均通过Harris髋关节评分进行临床评估，并进行了影像学评估。髋关节评分从术前的54分提高到术后的97分。17例患者的柄出现了5度至10度的内翻对线，但没有任何临床后果（Harris髋关节评分96.8）。我们记录了1例感染性松动和1例无菌性松动。根据Engh标准对柄的稳定性进行了影像学评估，证实其他所有病例均有骨长入。
