Rotator cuff tear or combined tears of the supraspinatus and infraspinatus. The migration can be measured by the distance between: Normally, the former is positioned inferiorly to the latter, and a reversal is therefore indicating a rotator cuff tear. Prolonged contact between a high-riding humeral head and the acromion above it, may lead to X-rays findings of wear on the humeral head and acromion and secondary degenerative arthritis of the glenohumeral joint (the ball and socket joint of the shoulder), called cuff arthropathy, may follow. Incidental X-ray findings of bone spurs at the adjacent acromioclavicular joint may show a bone spur growing from
Rotator cuff tear in frequency with age and the most common cause is age-related degeneration and, less frequently, sports injuries or trauma. Some risk factors of experiencing a rotator cuff tear cannot be changed: age, body mass index, and height. Recurrent lifting and overhead motions are at risk for rotator cuff tears. People who have jobs that involve overhead work, such as carpenters, painters, custodians and servers are at risk of also experiencing a rotator cuff tear. People who play sports that involve overhead motions, such as swimming, volleyball, baseball, tennis, and American football quarterbacks, are at a greater risk of experiencing a
