Rotator cuff tear surgery, although intellectually interesting, does not seem to demonstrate a statistically significant clinical difference. Biceps tenotomy and tenodesis are are often performed concomitantly with rotator cuff repair or as separate procedures and can be a sole or concomitant cause of shoulder pain. Tenodesis, which may be performed as an arthroscopic or open procedure, generally restores pain free motion it the biceps tendon, or attached portion of the labrum, is the cause of the pain. Tenotomy is a shorter surgery, requiring less rehabilitation, that doctors tend to recommended for older patients who don't mind the cosmetic 'popeye sign' that sometimes is
Rotator cuff arm, moving it outward and away from the trunk, the rotator cuff compresses the glenohumeral joint, an action known as concavity compression, in order to allow the large deltoid muscle to further elevate the arm. In other words, without the rotator cuff, the humeral head would ride up partially out of the glenoid fossa, lessening the efficiency of the deltoid muscle. The anterior and posterior directions of the glenoid fossa are more susceptible to shear force perturbations as the glenoid fossa is not as deep relative to the superior and inferior directions. The rotator cuff's contributions to concavity compression and
