Things that may increase the risk of rotator cuff disorders include:
- Having long-standing rotator cuff tendinitis.
- Holding or moving your arm overhead frequently, such as when you regularly paint; work as a waiter; or play tennis, baseball and other throwing sports.
- Previous shoulder injuries, such as dislocations and broken bones.
- Having a rotator cuff tear in the other shoulder.
- Irregularities of the muscles, tendons and bones in the shoulder that increase wear on the rotator cuff tendons.
- Having received multiple corticosteroid injections in the shoulder, which may weaken tendons and increase your risk.
- Smoking, which decreases the blood supply and slows the healing process.
- Shoulder instability.
As the rotator cuff and the shoulder weaken, the risk for a partial or complete tear increases.
