We evaluated intermediate-term results of primary cementless Omniflex prostheses. Forty-nine patients (57 hips) with a mean age of 44 years were observed for an average of 8.6 years. The average Harris hip score was 46 points before surgery and 87 points at final followup. Revision was done in five hips (9%) in five patients. Two acetabular components (4%) were revised because of breakage of the polyethylene insert. Three femoral components (5%) were revised because of aseptic loosening. Six femoral components (10%) were radiographically loose. Overall, 11 hips (19%) were considered mechanical failures. Osteolysis was identified around three acetabular components (5%) and around 20 femoral components (35%). Nine hips (16%) had femoral osteolysis around the distal stem tip. The average annual polyethylene liner wear was 0.18 mm. These results were inferior to those using other recent cementless total hip systems.
我们评估了初次使用非骨水泥型Omniflex假体的中期结果。观察了49例平均年龄44岁的患者（57髋），平均随访8.6年。术前平均Harris髋关节评分为46分，末次随访时为87分。5例患者的5髋（9%）进行了翻修。2个髋臼组件（4%）因聚乙烯内衬破裂而翻修。3个股骨组件（5%）因无菌性松动而翻修。6个股骨组件（10%）影像学显示松动。总体而言，11髋（19%）被认为是机械性失败。在3个髋臼组件（5%）周围和20个股骨组件（35%）周围发现骨溶解。9髋（16%）在股骨柄远端尖端周围出现股骨骨溶解。聚乙烯内衬的平均年磨损量为0.18 mm。这些结果不如使用其他近期非骨水泥全髋关节系统的结果。
