General research situation on the rotator cuff injury

The rotator cuff is a sleeve-shaped structure which is wrapping the humeral bone,also made up of the sinew in the supraspinatus muscle、infraspinatus muscle、lower-scapular muscle and knolls muscle.The investigaton shows that the rotator cuff injury takes a substantial proportion in shoulder joint desease.Through finding and reseaching relevent information,this paper has summerized physiological dissection of the rotator cuff,etiology and pathology of injury,providing the gist for the diagnose and treatment of this kind of illness,and it has a great significance in both academic and practical fields.
