Rotator cuff tear may have significance include os acromiale and acromial spurs. Environmental factors implicated include increasing age, shoulder overuse, smoking, and any medical condition that affects circulation or impairs the inflammatory and healing response, such as diabetes mellitus. Intrinsic factors refer to injury mechanisms that occur within the rotator cuff itself. The principal is a degenerative-microtrauma model, which supposes that age-related tendon damage compounded by chronic microtrauma results in partial tendon tears that then develop into full rotator cuff tears. As a result of repetitive microtrauma in the setting of a degenerative rotator cuff tendon, inflammatory mediators alter the local environment, and
Rotator cuff tear or arthritis. Superior labral anterior-posterior lesions produce pain similar to that of rotator cuff tears. Those most prone to failed rotator cuff syndrome are patients 65 years of age or older; and those with large, sustained tears. Smokers, diabetes sufferers, patients with muscle atrophy and/or fatty infiltration, and those who do not follow postoperative-care recommendations also are at greater risk. Doctors examine patients and conduct imaging tests to identify the causes of continued discomfort. Depending upon the diagnosis, several treatment alternatives are available. They include revision repair, nonanatomic repair, tendon transfer and arthroplasty. When possible, surgeons make tension-free repairs in
