Abstract

Background: The risk of falls causing periprosthetic fracture has become an issue with the increase in the number of patients undergoing long-term follow-up after total hip arthroplasty (THA) and the aging of patients. The Timed Up and Go test (TUG) is utilized to evaluate fall risk. This study investigated muscle volume around the hip joint based on computed tomography (CT), CT value, and muscle strength to investigate contributing factors to poor TUG 1 year post-THA.

Methods: This study retrospectively investigated 124 patients with unilateral hip osteoarthritis who underwent THA and classified them based on TUG results at 1 year postoperatively into TUG of < 10 s (fast group [103 patients]) and ≥ 10 s (slow group [21 patients]). Body mass index, the volume and CT density of the psoas major and gluteus medius muscles on CT images, pre- and postoperative hip flexion muscle strength, and hip abductor muscle strength were compared in each group.

Results: Age was significantly older and preoperative abductor (fast Group: 1.0 ± 0.3 and slow Group: 0.7 ± 0.3, P = 0.003) and flexion muscle strengths (0.9 ± 0.3 and 0.7 ± 0.3, respectively, P = 0.02) on the healthy side were significantly lower in the slow group. The gluteus medius muscle demonstrated significantly lower CT density in the slow group on both sides. Nominal logistic regression analysis revealed that age and preoperative healthy abductor muscle strength, which are poor factors for TUG 1 year post-THA, were significantly associated with TUG of ≥ 10 s at 1 year post-THA.

Conclusions: The poor factors for TUG 1 year after THA were age and preoperative abductor muscle strength on the healthy side.

女性全髋关节置换术后，术前健侧外展肌力量对定时起立行走测试的影响。

背景：随着接受全髋关节置换术（THA）后长期随访的患者人数增加以及患者年龄的增长，跌倒导致假体周围骨折的风险已成为一个问题。定时站立行走测试（TUG）可用于评估跌倒风险。本研究根据计算机断层扫描（CT）、CT值和肌肉力量调查了髋关节周围的肌肉体积，以研究THA术后1年TUG不良的诱因：本研究回顾性调查了124名接受THA的单侧髋关节骨关节炎患者，并根据术后1年的TUG结果将其分为TUG、TUG、TUG、TUG、TUG、TUG、TUG、TUG、TUG、TUG 结果：年龄明显偏大，术前健侧外展肌力（快速组：1.0 ± 0.3，慢速组：0.7 ± 0.3，P = 0.003）和屈曲肌力（分别为 0.9 ± 0.3 和 0.7 ± 0.3，P = 0.02）明显低于慢速组。慢速组两侧臀中肌的 CT 密度均明显较低。名义逻辑回归分析显示，年龄和术前健康外展肌肌力是影响THA术后1年TUG的不良因素，与THA术后1年TUG≥10 s有明显相关性：结论：影响THA术后1年TUG的不良因素是年龄和术前健侧外展肌力。
