Thirty-two elderly patients with a femoral neck fracture treated by bipolar hemiarthroplasty and 36 patients (matched for age) with an Austin-Moore hemiarthroplasty were followed-up and compared. Bipolar replacement resulted in a higher percentage of satisfactory results, less postoperative pain, greater range of movement, more rapid return to unassisted activity, fewer unsatisfactory results and no acetabular erosion. The device functioned as bipolar in all the cases studied for inner-bearing motion.
对32例采用双极半髋关节置换术治疗的老年股骨颈骨折患者和36例（年龄匹配）采用奥斯汀-摩尔半髋关节置换术的患者进行了随访和比较。双极置换术取得满意结果的比例更高，术后疼痛更少，活动范围更大，恢复自主活动更快，不满意结果更少，且无髋臼侵蚀。在所有研究的病例中，该装置在内部承重运动时均发挥双极作用。
