What Causes Rotary Cuff Tears?

Athletes such as football players, tennis players, baseball players and swimmers are prone to rotator cuff injuries. The rotator cuff is defined as "a group of four tendons and muscles that converge around the top of the humerus, the upper arm bone above the elbow," writes WebMD. These tendons form the "cuff," which keeps an arm in place. Stress on the tendons--from excess weigh lifting or other trauma--can cause tears.

Falling on a Shoulder

• If you fall on your shoulder, it is possible to tear your rotator cuff. The pain in your shoulder should grow gradually if you have torn one or more tendons. You also may feel weakness or tenderness in your shoulder, writes WedMD.

Breaking a Fall with an Arm

• If you break a fall with your arm or shoulder, you can cause your rotator cuff to tear. If you have trouble moving your arm or shoulder--such as difficultly lifting your arm or stretching it above your head--then its is possible you have a tear. Also, if you hear a "snapping or crackling" noise when you move your shoulder, you may have torn your cuff, reports WebMD. Consult your physician.

Lifting Heavy Weights

• Athletes--especially baseball pitchers--who put stress on their arms or who lift heavy weights frequently can tear their rotator cuffs. Do not lift weights without consulting trained professionals first, and do not lift beyond your limit too quickly. Rotator cuff tears can heal on their own, but extensive tears require surgery.
