Right Shoulder Injuries and Repair
This exhibit depicts the anterior anatomy of the shoulder, impingement syndrome, and tearing of the supraspinatus tendon with subsequent repairs. Anatomical structures include: the clavicle, coracoid process, acromion process, glenoid, supraspinatus, humerus, bursa, glenohumeral joint capsule, biceps brachii, and the scapula. Impingement syndrome occurs when the subacromial bursa is pinched as it attempts to glide between the supraspinatus and acromioclavicular joint during shoulder abduction. This, along with tearing of the supraspinatus tendon, can result in pain and weakness of the shoulder joint. Surgical repairs are achieved by resecting the coracoacromial ligament, removing the subacromial bursa, removing the acromioclavicular joint spurs, and suturing the supraspinatus tear.
