Abstract：
OBJECTIVE: Distal radius fracture (DRF), sarcopenia, and malnutrition have been reported to be interrelated. However, there are few reports on the effects of sarcopenia and malnutrition on DRF patients\' postoperative outcomes. This study examined the healthy-side grip strength and preoperative blood tests to determine the presence of possible sarcopenia (PS) and malnutrition in geriatric women with DRF and their impact on postoperative functional outcomes.
METHODS: Fifty-five woman older than 60 years treated with volar-locking plate fixation for low-energy DRF from standing-level falls were retrospectively studied. Based on the criteria of The Asian Working Group for Sarcopenia 2019, patients with a healthy-side grip strength <18 kg were defined as PS. Nutritional assessment was performed using Onodera\'s Prognostic Nutritional Index (PNI) before surgery, with a value <50 defined as malnutrition. The Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) was used for functional assessment at 1 year after surgery. Patients were divided into two groups according to PS, and patient demographic data and postoperative outcomes were compared. Multiple regression analysis was performed to estimate the regression coefficient and 95% confidence intervals for 1-year QuickDASH after surgery with adjustment for age, PS, and malnutrition.
RESULTS: Possible sarcopenia was present in 10 patients (18.2%), and malnutrition in 24 patients (43.6%). Possible sarcopenia patients were older, had lower PNI, serum albumin, and both sides grip strength, and worse QuickDASH compared with non-PS patients. In multiple regression analysis, age, PS, and malnutrition were significant predictors of QuickDASH (standardized coefficient β, 0.35, 0.34, and 0.24; 95% confidence interval, 0.22-1.02, 3.52-16.49, and 0.50-10.78).
CONCLUSIONS: Possible sarcopenia with a healthy-side grip strength <18 kg and malnutrition with a PNI <50 were associated with worse 1-year QuickDASH after surgery in women DRF patients over 60 years.
METHODS: Prognostic Ⅳ.

摘要：
目的：桡骨远端骨折（DRF），少肌症,据报道，营养不良是相互关联的。然而,关于肌肉减少症和营养不良对DRF患者术后结局的影响的报道很少。这项研究检查了健康侧的握力和术前血液检查，以确定患有DRF的老年女性可能存在的肌肉减少症（PS）和营养不良及其对术后功能结果的影响。
方法：回顾性研究了55名60岁以上的女性，该女性接受掌侧锁定钢板内固定治疗，以治疗站立水平跌倒引起的低能量DRF。根据2019年肌肉减少症亚洲工作组的标准，将健康侧握力<18kg的患者定义为PS。术前使用Onodera的预后营养指数（PNI）进行营养评估，值<50定义为营养不良。手臂的快速残疾，肩膀,和手（QuickDASH）用于术后1年的功能评估。根据PS将患者分为两组，比较了患者的人口统计学数据和术后结局.进行多元回归分析以估计手术后1年QuickDASH的回归系数和95％置信区间，并调整年龄，PS,和营养不良。
结果：10例患者（18.2%）存在可能的肌少症，营养不良24例(43.6%)。可能的肌肉减少症患者年龄较大，PNI较低，血清白蛋白,双方握力，与非PS患者相比，QuickDASH更差。在多元回归分析中，年龄,PS,和营养不良是QuickDASH的重要预测因子(标准化系数β，0.35、0.34和0.24；95%置信区间，0.22-1.02、3.52-16.49和0.50-10.78）。
结论：健康侧握力<18kg的肌肉减少症和PNI<50的营养不良与60岁以上女性DRF患者术后1年QuickDASH恶化相关。
方法：预后Ⅳ.
