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 these studies we see that the percentages of the prevalence of a rotator cuff tear are very close in number so these numbers show us the prevalence of rotator cuff tears in the general population. In an autopsy study of rotator cuff tears, the incidence of partial tears was 28%, and of complete rupture 30%. Frequently, tears occurred on both sides and the frequency increased with age. The frequency was also higher in females. Other cadaver studies have noted intratendinous tears to be more frequent (7.2%) than bursal-sided (2.4%) or articular-sided tears (3.6%). However, clinically, articular-sided tears are found to
