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. 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. 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. 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.
股骨颈骨折是最常见的骨折类型之一，尤其影响老年患者。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方面的作用仍不完全清楚。接受THA或BA的患者被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40米的行走距离以及其间的转身动作。在步态分析过程中，记录测量持续时间、最大峰值力和平均峰值力。总共纳入了39例患者，其中25例接受了BA，14例接受了THA。在步态分析中，BA组的最大峰值力平均为体重的80.6%±19.5%，THA组为78.9%±21.6%。在整个步态分析中额外测定的平均峰值力，BA组为体重的66.8%±15.8%，THA组为60.5%±15.6%。接受THA和BA治疗的股骨颈骨折患者在术后早期患侧腿能够实现足够的负重。在我们的研究中，与THA相比，BA的平均和最大负荷能力并没有显著更高。
