A distal radius fracture (DRF) is commonly the first fracture to occur in early postmenopausal women. The reasons for sustaining a DRF may be related to fall risk, bone fragility, or both. The objective of this study was to compare functional and fracture risk status in postmenopausal women with and without a recent DRF and explore the relationships between function, grip strength, and fracture risk status. Seventy-seven women a ges 50-78 with (n = 32) and without (n = 45) a history of DRF in the past 2 years participated. Balance, timed up and go (TUG), gait velocity, balance confidence, sit to stand, grip strength, and fracture risk were assessed. There was a significant group difference after controlling for physical activity level (Pillai's Trace, p < .05) where women with DRF had poorer outcomes on sit to stand, gait velocity, TUG, and fracture risk status. Grip strength was associated with functional tests, particularly in women with DRF. Women with a recent DRF demonstrated lower functional status and higher fracture risk compared to women without. Grip strength was associated with measures of function and fracture risk, and may complement screening tools for this population.
桡骨远端骨折（DRF）通常是绝经后早期女性发生的首例骨折。发生DRF的原因可能与跌倒风险、骨质脆弱或两者都有关。本研究的目的是比较有和没有近期DRF的绝经后女性的功能和骨折风险状况，并探讨功能、握力与骨折风险状况之间的关系。77名年龄在50 - 78岁之间的女性参与了研究，其中32名有过去2年DRF病史，45名无该病史。评估了平衡能力、计时起立行走测试（TUG）、步态速度、平衡信心、从坐到站的能力、握力和骨折风险。在控制身体活动水平后存在显著的组间差异（Pillai检验，p < 0.05），有DRF的女性在从坐到站、步态速度、TUG和骨折风险状况方面的结果较差。握力与功能测试相关，尤其是在有DRF的女性中。与没有近期DRF的女性相比，有近期DRF的女性功能状态较低且骨折风险较高。握力与功能和骨折风险的测量相关，可能对该人群的筛查工具起到补充作用。
