What is a rotator cuff?

Answer 1

The rotator cuff is a group of tendons and their related muscles that helps keep the upper arm bone securely placed, or seated, into the socket of the shoulder blade. Rotator cuff disorders are usually caused by a combination of factors, such as normal wear and tear. Age-related degeneration slowly damages the rotator cuff, causing one or more tendons to rub against the bones (impingement). Partial or complete tears to the rotator cuff tendon are more likely to occur when the rotator cuff is already scarred, weakened, or damaged. A complete rotator cuff tear in a person with an otherwise healthy shoulder is most often caused by an extremely forceful injury. PAINPAIN!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
