摘　　要：目的通过MRI测量正常第二肩关节肩峰外侧点到肱骨头(A-H)之间的距离,根据不同性别、身高、体重、年龄进行分组,比较不同分组间的统计学差异。方法对200例健康成人志愿者采用1.5 T MRI设备测量中立位位置时A-H距离。根据不同的性别、身高、体重、年龄进行分组,并进行统计学分析。结果 200例健康成人志愿者中,测得A-H距离最大为14.8 mm,最小为7.8 mm。A-H距离男性大于女性,差异有统计学意义(P<0.05)。按身高分为<160、160~169、170~179、≥180 cm 4组,除身高≥180 cm组与<160 cm组AH距离比较差异有统计学意义(P<0.05)外,其他各组两两比较差异均无统计学意义(P>0.05)。按BMI分为<18.5、18.5~24.99、≥25 kg/m23组,3组两两比较差异均无统计学意义(P>0.05)。按年龄≤40、41~65、≥66岁分为3组,3组两两比较差异均无统计学意义(P>0.05)。结论 A-H距离有性别及身高差异,体重、年龄各组差异无统计学意义,可以解释女性患者肩峰下撞击综合征患病率高的现象。Objective To measure the distance between the lateral point of acromion to the head of humerus （A-H） of nomoral subarcromial space by MRI, and divid into different groups by gender, height, weight, age, to understand different groups whether have statistical significance. Methods The 200 healthy adult volunteers were selected, ap- plied 1.5 T MRI examination to measure the A-H distance in neutral position, and then were divided into different groups according to the gender,height,weight,age, the data were statistically analyzed. Results The maximum A-H distance was 1,4. 8 mm, the minimum was 7.8 mm. The A-H distance between the male and female was statistical significance（P 〈 0. 05 ）, and the male was longer than the female. Divided different height into 〈 160,160 -169, 170 -179, ≥ 180 cm 4 groups,the A-H distance between groups of≥180 cm and 〈 160 cm were statistical signifi- cant difference （ P 〈 0. 05 ） , the other groups had no significant difference （ P 〉 0. 05 ）. According to BMI, divided into 〈 18. 5,18.5 - 24. 99,25 kg/m2 3 groups, all 3 groups had no significant difference （ P 〉 0. 05 ）. According to age, divided into ≤40,41 - 65,≥66 years 3 groups, all 3 groups had no statistical significance（ P 〉 0. 05 ）. Conclusions The A-H distance has statistical significance in gender and height, and has no statistical significance in weight, age, which can explain the phenomenon that women patients have the high prevalence of subacromial impingement syndrome.
