Purpose

The presence of os acromiale is of clinical relevance before performing shoulder surgery but ethnic differences and little information regarding associated factors seem to be present. Population-based studies to clarify these topics are essential so the purpose of this study was to assess the prevalence, anatomy, and associations of os acromiale in a general adult population.

Methods

Both shoulders of 3050 participants from the population-based Study of Health in Pomerania (SHIP) were assessed on magnetic resonance imaging (MRI). Associations with the os acromiale were calculated for sex, age, body height, body weight, and heavy mechanical oscillations on the upper extremity.

Results

In total, 1.9% (58/3050) had an os acromiale, while 21 were unilateral left, 23 were unilateral right, and 14 were bilateral. Sixty-eight meso-acromions, three pre-acromions, and one meta-acromion were detected. Os acromiale were more frequent in men (right side: p = 0.037, left side: p = 0.005). Overall, no differences in sides (p = 0.808), to participants’ age (right: p = 0.993, left: p = 0.499), body height (right side: p = 0.241, left side: p = 0.154), and the exposure to heavy mechanical oscillations on the upper extremity (right: p = 0.054, left: p = 0.117) were detected.

Conclusion

Our results support the genetic theory for the aetiology of the os acromiale due to the lower prevalence of the os acromiale in north-eastern Germany compared to the worldwide prevalence (1.9 to 7%) and the lacking association to lifestyle, age, gender, or sides. Additionally, it is important to be aware of possible os acromiale before surgery.

Os acromiale：患病率和相关的患者相关因素——一项针对 350 名参与者的基于人群的研究

目的

肩峰的存在在进行肩部手术之前具有临床相关性，但似乎存在种族差异和有关相关因素的信息很少。阐明这些主题的基于人群的研究至关重要，因此本研究的目的是评估一般成年人群中肩胛骨的患病率、解剖结构和相关性。

方法

来自基于人群的波美拉尼亚健康研究 (SHIP) 的 3050 名参与者的双肩接受了磁共振成像 (MRI) 评估。计算性别、年龄、身高、体重和上肢重度机械振动与肩胛骨的关联。

结果

总共有 1.9% (58/3050) 有肩胛骨，21 例为左侧单侧，23 例为右侧单侧，14 例为双侧。检测到 68 个中肩峰、3 个前肩峰和 1 个中肩峰。肩峰在男性中更为常见（右侧：p = 0.037，左侧：p = 0.005）。总体而言，两侧（p = 0.808）、参与者年龄（右侧：p = 0.993，左侧：p = 0.499）、身高（右侧：p = 0.241，左侧：p = 0.154）和检测到暴露于上肢严重的机械振荡（右：p = 0.054，左：p = 0.117）。
