OBJECTIVE
The aims were to study the acromion parameters in the population and to assess the extremity or sex variation in the acromion morphology.
METHODS
The lateral acromion angle (LAA) and the acromion index (AI) were assessed in a computed tomographic scan database of 250 individuals in the age group of 20 to 49 years. For the analysis of LAA and AI, 286 and 234 shoulders were available, respectively.
RESULTS
The LAA was 73.6 ± 6.6 degrees; 73.7 ± 6.9 and 72.5 ± 6.1 degrees for the right and left shoulder, respectively. The AI was 0.755 ± 0.12; 0.82 ± 0.12 and 0.69 ± 0.12 for the left and the right shoulder, respectively. The AI of the right shoulder was significantly different between the 2 sexes (P = 0.04). The difference in the AI and the LAA of the right and left shoulders was significant (P < 0.0001, P = 0.04).
CONCLUSIONS
The morphology of the acromion differs between the right and the left shoulders as well as between sexes.
目的
研究人群中的肩峰参数，并评估肩峰形态在肢体或性别上的差异。
方法
在一个包含250名年龄在20至49岁之间个体的计算机断层扫描数据库中评估外侧肩峰角（LAA）和肩峰指数（AI）。对于LAA和AI的分析，分别有286个和234个肩部可供研究。
结果
LAA为73.6±6.6度；右肩和左肩分别为73.7±6.9度和72.5±6.1度。AI分别为0.755±0.12；左肩和右肩分别为0.82±0.12和0.69±0.12。右肩的AI在两性之间存在显著差异（P = 0.04）。左右肩的AI和LAA差异显著（P < 0.0001，P = 0.04）。
结论
肩峰形态在左右肩之间以及两性之间存在差异。
