摘　　要：背景:应用钩钢板固定治疗肩关节损伤或合并锁骨远端骨折时,钩钢板钩部的角度固定不变,而人体肩锁关节正常角度或在上臂运动时会发生相关变化。目的:探讨正常肩锁关节倾斜角度与肩关节活动相关性,及其临床意义。方法:纳入包含肩部CT检查的TOP图像资料97例,其中男57例,女40例,选择CT时TOP图像,在CT上用机器进行角度测量。肩锁关节角度:为肩峰长轴沿线与锁骨远端长轴沿线的夹角,盂肱关节的角度为肱骨外展与垂线的角度。结果及结论:在上肢下垂时平均肩锁角为(162.04±10.53)°。下垂平均肱骨角为(16.06±11.87)°,R=0.010(P<0.01),说明肩关节与肩锁关节两个角度相关。在上肢上举时肩锁角(174.34±10.14)°,上举肱骨角(137.65±14.48)°,R=0.053(P<0.01)两个角度也是相关的。提示,肩锁关节角度在肱骨上举运动时发生变化。肩关节活动时肩锁关节相关活动,既盂肱关节活动时,肩锁关节角度也随之变化。BACKGROUND：The angle of the hook of the clavicular hook plate could not change in application of dislocation of acromioclavicular joint and or fracture of the clavicle distal end.But the angle of the acromioclavicular joint will change somewhat during the glenohumeral joint abduction.OBJECTIVE：To investigate the normal acromioclavicular joint value and its relation to glenohumeral joint motion during abduction as well as their clinical significance.METHODS：A total of 97 cases with their TOP images among the CT data containing the shoulder joints were selected,including 57 males and 40 females.The angle of acromioclavicular joint values on the screen of the CT monitor was measured.The angle of acromioclavicular joint is the included angle between the major axis of acromeon and the major axis of clavicle distal part.The glenohumeral joint angle is the major axis of humoros in abduction and vertical line.RESULTS AND CONCLUSION：The average angle of the acromioclavicular joint was（162.04±10.53）° when the glenohumeral joint angle at（16.06±11.87）°（R=0.010,P 0.000）,suggesting the correlation between two angles.The average angle of the acromioclavicular joint was（174.34±10.14）° when the glenohumeral joint angle at（137.64±14.48）°（R=0.053,P 0.01）suggesting the correlation between two angles.Results indicate that the acromioclavicular joint angle is changing during active humeral elevation.The acromioclavicular joint angle moves during glenohumeral joint angle change.
