In this case-control study, we concluded that women with distal radial fractures who were surgically treated showed lower grip strength and dynamic body balancing than those of controls. These results suggest that measurements of grip strength and dynamic body balance may be useful screening tools to assess future fracture risk.
Patients with distal radial fractures (DRFs) are at risk of future fragility fractures. However, their physical characteristics and tendencies for falls remain unclear. We aimed to compare the physical characteristics of women with and without distal radial fractures.
We included 128 women with a DRF as their first fragility fracture (fracture group) who underwent surgical treatment. Concurrently, 128 age- and sex-matched participants without a history of fragility fractures were selected as controls (control group). The participants underwent assessments of grip strength and the body balancing ability test. Measurements were taken twice in the fracture group, at 2 weeks and 6 months postoperatively, and once in the control group. The body balancing ability test included the Functional Reach Test, Timed Up and Go test (TUG), 2-Step test (2ST), and Timed Uni-pedal Stance test. The participants also completed questionnaires about their health.
There were no significant differences (p > 0.05) in patient characteristics between the groups. The fracture group showed lower grip strength across all age groups. In the DRF group, prolonged TUG time was observed at 2 weeks postoperatively in all age groups and at 6 months in participants aged 55-74 years; the 2ST score was significantly lower in participants aged between 65 and 74 years.
Women with DRF demonstrated lower grip strength and dynamic body balancing ability. Lower grip strength and dynamic body balancing ability were identified as significant risk factors in women with DRF, suggesting that these may be useful screening tools to assess fracture risk.
本病例对照研究的结论是，接受手术治疗的桡骨远端骨折女性的握力和动态身体平衡能力低于对照组。这些结果表明，握力和动态身体平衡能力的测量可能是评估未来骨折风险的有用筛查工具。
桡骨远端骨折（DRF）患者有发生未来脆性骨折的风险。然而，他们的身体特征和跌倒倾向仍不清楚。我们旨在比较有和无桡骨远端骨折女性的身体特征。
我们纳入了 128 名首次发生脆性骨折（骨折组）的女性患者，这些患者接受了手术治疗。同时，选择了 128 名年龄和性别匹配、无脆性骨折史的参与者作为对照组（对照组）。参与者接受了握力和身体平衡能力测试评估。在骨折组中，分别在术后 2 周和 6 个月进行了 2 次测量，在对照组中进行了 1 次测量。身体平衡能力测试包括功能性伸展测试、计时起立-行走测试（TUG）、2 步测试（2ST）和计时单足站立测试。参与者还完成了关于他们健康状况的问卷。
两组患者的特征无显著差异（p>0.05）。在所有年龄组中，骨折组的握力均较低。在 DRF 组中，所有年龄组在术后 2 周时 TUG 时间延长，65-74 岁年龄组在术后 6 个月时 TUG 时间延长；65-74 岁年龄组的 2ST 评分显著降低。
桡骨远端骨折女性的握力和动态身体平衡能力较低。桡骨远端骨折女性的握力和动态身体平衡能力降低被确定为桡骨远端骨折的显著危险因素，表明这些可能是评估骨折风险的有用筛查工具。
