Rotator Cuff Tears
When one or more of the rotator cuff tendons are partially or completely torn, the tendon is no longer fully attached to the humerus. An acute tear can be caused by a fall or lifting something too heavy. A degenerative tear is the result of wear and tear over time caused by repeating the same motion. Symptoms include pain and weakness when lifting, lowering or rotating the arm, and crepitus (cracking / grinding / crunching sounds) when moving the shoulder.
