OBJECTIVE
To evaluate the position of the acromioclavicular joint (ACJ) and relation to the critical shoulder angle (CSA) in shoulders with rotator cuff tears (RCT).
METHODS
In a matched pair study including 75 shoulders with arthroscopically validated RCT and 75 controls (mean age 59.4 ± 7.9 years) the position of the ACJ in relation to the glenoid and the CSA were measured on true ap radiographs.
RESULTS
The CSA is larger (p = 0.0018) and the position of the ACJ is more lateral (p = 0.0016) in shoulders with RCT in comparison to matched controls.
CONCLUSION
The more lateral position of the ACJ in shoulders with a large CSA might be an additional component in the multifactorial pathogenesis of RCT.
目的
评估肩袖撕裂（RCT）患者肩关节中肩锁关节（ACJ）的位置及其与临界肩角（CSA）的关系。
方法
在一项配对研究中，纳入75例经关节镜证实为RCT的肩关节和75例对照（平均年龄59.4±7.9岁），在真正的前后位X线片上测量ACJ相对于肩胛盂的位置和CSA。
结果
与配对对照相比，RCT患者的肩关节中CSA更大（p = 0.0018），ACJ的位置更靠外侧（p = 0.0016）。
结论
在CSA较大的肩关节中，ACJ位置更靠外侧可能是RCT多因素发病机制中的一个额外因素。
