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
Giant-cell tumor of the tendon sheath Giant-cell tumor of the tendon sheath Giant-cell tumor of the tendon sheath, also known as giant-cell synovioma and localized nodular tenosynovitis, is a firm lesion, measuring 1 to 3 cm in diameter, and is most commonly attached to the tendons of the fingers, hands, and wrists, with a predilection for the flexor surfaces. Giant-cell tumor of tendon sheaths most often affect the wrist and fingers of males and females from the ages of 20-50 . These tumors are typically painless and can cause cortical erosion. Surgery to remove the tumor is a common treatment, though the tumors tend to recur.
