The association between distally pointing osteophytes of the acromioclavicular joint and ruptures of the supraspinatus tendon was investigated by two different methods. In a radiologic study, 47 images of shoulders with arthrographically confirmed supraspinatus tendon ruptures were reviewed and compared with 50 images of shoulders without ruptures. Fifty-one percent of the shoulders with supraspinatus tendon ruptures had osteophytes, as compared with 14% of the normal shoulders. A series of 170 autopsy specimens of the shoulder were also examined in detail; partial supraspinatus tendon ruptures were found in 32 and full-thickness ruptures in 22 shoulders. Fifty-four percent of the shoulders with supraspinatus tendon ruptures had distally pointing acromioclavicular osteophytes, as compared with 10% of the normal shoulders. Bony spurs of the anterior acromial process were also encountered, but they were less frequent than the acromioclavicular osteophytes.
采用两种不同方法研究了肩锁关节远端骨赘与冈上肌腱断裂之间的关联。在一项放射学研究中，对47例经关节造影证实有冈上肌腱断裂的肩部影像进行了回顾，并与50例无断裂的肩部影像进行了比较。冈上肌腱断裂的肩部中有51%存在骨赘，而正常肩部中这一比例为14%。还对一系列170例肩部尸检标本进行了详细检查；发现32例肩部有冈上肌腱部分断裂，22例肩部有全层断裂。冈上肌腱断裂的肩部中有54%存在肩锁关节远端骨赘，而正常肩部中这一比例为10%。还发现了肩峰前缘的骨棘，但它们比肩锁关节骨赘少见。
