Abstract：
Background: Femoral neck fractures are among the most common types of fractures and particularly affect elderly patients. Two of the most common treatment strategies are total hip arthroplasty (THA) and bipolar hemiarthroplasty (BA). However, the role of the different treatment strategies in the postoperative weight-bearing ability in the early postoperative phase is still not entirely clear. Methods: Patients who underwent either THA or BA were consecutively included in our prospective cohort study. Gait analysis was performed during the early postoperative period. The gait analysis consisted of a walking distance of 40 m coupled with the turning movement in between. During the gait analysis, the duration of the measurement, the maximum peak force and the average peak force were recorded. Results: A total of 39 patients were included, 25 of whom underwent BA and 14 of whom underwent THA. The maximum peak force during the gait analysis was, on average, 80.6% ± 19.5 of the body weight in the BA group and 78.9% ± 21.6 in the THA group. The additionally determined average peak force during the entire gait analysis was 66.8% ± 15.8 of the body weight in the BA group and 60.5% ± 15.6 in the THA group. Conclusions: Patients with femoral neck fractures undergoing THA and BA can achieve sufficient weight bearing on the operated leg in the early postoperative period. In our study, BA did not allow for a significantly higher average and maximum loading capacity compared with THA.
摘要：
背景：股骨颈骨折是最常见的骨折类型之一，尤其会影响老年患者。两种最常见的治疗策略是全髋关节置换术（THA）和双极半髋关节置换术（BA）。然而,不同治疗策略在术后早期负重能力中的作用尚不完全清楚.方法：将接受THA或BA的患者连续纳入我们的前瞻性队列研究。在术后早期进行步态分析。步态分析包括40m的步行距离以及两者之间的转弯运动。在步态分析中,测量的持续时间，记录最大峰值力和平均峰值力。结果:共纳入39例患者,其中25人接受了BA，14人接受了THA。步态分析期间的最大峰值力为,平均而言,BA组体重为80.6%±19.5,THA组体重为78.9%±21.6。在整个步态分析期间额外确定的平均峰值力为BA组体重的66.8%±15.8和THA组体重的60.5%±15.6。结论：股骨颈骨折患者行THA和BA术后早期可以在手术腿上获得足够的负重。在我们的研究中,与THA相比，BA不允许显着更高的平均和最大负载能力。
