Abstract：
UNASSIGNED: The potential role of deltoid muscle density in the occurrence of proximal humeral fractures remains uncertain. Therefore, the primary objective of this study was to examine the correlation between deltoid muscle density, as measured by CT attenuation value in Hounsfield units (HU), and the incidence of proximal humeral fractures in elderly patients. By investigating this association, we aim to shed light on the possible influence of deltoid muscle density on fracture risk in this specific population.
UNASSIGNED: A total of 68 patients with computed tomography (CT) images were retrospectively reviewed. Among them, 34 patients presented with fractures following low-energy injuries, while the remaining 34 patients served as controls and underwent CT scans after low-energy injuries without any fractures. The muscle density of the deltoid muscles was assessed at the approximate tubercle of humerus. We compared these parameters between the two groups and conducted analyses considering factors such as age, sex, laterality, and deltoid muscle density of the shoulders.
UNASSIGNED: The demographic factors related to the shoulder did not exhibit any significant association with proximal humeral fracture. However, we observed a noteworthy difference in deltoid muscle density between patients with fractures (40.85 ± 1.35) and the control group (47.08 ± 1.61) (p = 0.0042), indicating a lower muscle density in the fracture group.
UNASSIGNED: Based on the findings of this study, we can conclude that there exists a negative correlation between deltoid muscle density and the incidence of proximal humeral fractures. These results suggest that lower deltoid muscle density may be associated with an increased risk of proximal humeral fractures in the elderly population under investigation.

摘要：
■三角肌密度在肱骨近端骨折发生中的潜在作用仍不确定。因此,这项研究的主要目的是检查三角肌密度之间的相关性，通过以Hounsfield单位(HU)为单位的CT衰减值测量，老年患者肱骨近端骨折的发生率。通过调查这个协会，我们的目的是阐明三角肌密度对这一特定人群骨折风险的可能影响.
■对总共68例患者的计算机断层扫描（CT）图像进行回顾性分析。其中,34例患者在低能量损伤后出现骨折，而其余34例患者作为对照，在低能量损伤后接受了CT扫描，没有任何骨折。在肱骨的近似结节处评估三角肌的肌肉密度。我们比较了两组之间的这些参数，并考虑了年龄等因素进行了分析，性别,偏侧性,和肩部的三角肌密度。
■与肩关节相关的人口统计学因素与肱骨近端骨折没有任何显著关联。然而,我们观察到骨折患者的三角肌密度（40.85±1.35）和对照组（47.08±1.61）之间存在显著差异（p=0.0042），表明骨折组的肌肉密度较低。
■根据本研究的结果，我们可以得出结论，三角肌密度与肱骨近端骨折的发生率之间存在负相关。这些结果表明，在接受调查的老年人群中，较低的三角肌密度可能与肱骨近端骨折的风险增加有关。
