Sarcopenia poses a risk factor for falls, disability, mortality, and unfavorable postoperative outcomes. Recently, the Ultrasound Sarcopenia Index (USI) has been validated to assess muscle mass, and this study aimed to apply the USI in the clinical setting.
This prospective observational study included 108 patients aged >65 years, hospitalized for proximal femoral traumatic fracture. Patients were divided into two groups based on anamnestic data: patients with independent walking (IW) and patients requiring walking aid (WA) before admission. All the participants received an ultrasound examination. Other parameters evaluated were handgrip strength, limb circumferences, nutrition (MNA), and activity of daily living (ADL) scores.
Fifty-six IW patients (83 ± 6 y; 38 females) and 52 WA patients (87 ± 7 y; 44 females) were recruited. The USI was significantly higher in the IW group compared to the WA group ( = 0.013, Cohen's = 0.489). Significant correlations were found between the USI and other sarcopenia-associated parameters, such as handgrip strength, MNA, ADLs, other muscle ultrasound parameters, and limb circumferences.
The application of the USI in the orthopedic surgery setting is feasible and might support the diagnosis of sarcopenia when combined with other measures of strength and function.
肌少症是导致跌倒、残疾、死亡和术后不良结局的危险因素。最近，超声肌少症指数（USI）已被验证可用于评估肌肉量，本研究旨在将 USI 应用于临床。
这是一项前瞻性观察性研究，纳入了 108 名年龄>65 岁、因股骨近端创伤性骨折住院的患者。根据病史资料将患者分为两组：独立行走（IW）组和入院前需要助行器行走（WA）组。所有参与者均接受超声检查。评估的其他参数包括握力、四肢周径、营养（MNA）和日常生活活动（ADL）评分。
共纳入 56 名 IW 患者（83 ± 6 岁；38 名女性）和 52 名 WA 患者（87 ± 7 岁；44 名女性）。与 WA 组相比，IW 组的 USI 显著更高（ = 0.013，Cohen's = 0.489）。USI 与其他与肌少症相关的参数之间存在显著相关性，如握力、MNA、ADL、其他肌肉超声参数和四肢周径。
USI 在骨科手术环境中的应用是可行的，当与其他力量和功能测量指标结合使用时，可能有助于肌少症的诊断。
