Shoulder the coracohumeral ligament, and the glenohumeral ligament complex, blend into a confluent sheet before insertion into the humeral tuberosities. The infraspinatus and teres minor fuse near their musculotendinous junctions, while the supraspinatus and subscapularis tendons join as a sheath that surrounds the biceps tendon at the entrance of the bicipital groove. Muscles from the shoulder region In addition to the four muscles of the rotator cuff, the deltoid muscle and teres major muscles arise and exist in the shoulder region itself. The deltoid muscle covers the shoulder joint on three sides, arising from the front upper third of the clavicle,
Rotator cuff tear cuff, allowing for the repair of the cuff without disruption of the deltoid origin. The results of decompression alone tend to degrade with time, but the combination of repair and decompression appears to be more enduring. Repair of a complete, full-thickness tear involves tissue suture. The method currently in favor is to place an anchor in the bone at the natural attachment site, with resuture of torn tendon to the anchor. If tissue quality is poor, mesh (collagen, Artelon, or other degradable material) may be used to reinforce the repair. Repair can be performed through an open incision, again requiring
