According to the American Academy of Orthopaedic Surgeons (AAOS), most rotator cuff tears are the result of overusing the muscles and tendons in the shoulder. Also, rotator cuff tears are most common in people over the age of 40.
Sudden, Hard Movement
Acute tears to the rotator cuff are the result of a sudden or powerful movement like a hard-throwing pitcher in baseball, according to the Sports Injury Clinic (SIC).
Repetitive Motions
Chronic tears are the result of repetitive movements that develop over time, according to the SIC. These types of tears are commonly seen in baseball and tennis players due to their repetitive throwing and swinging movements.
Symptoms
According to the AAOS, the most common symptoms in acute tears are severe pain and limited mobility of the shoulder. In chronic tears, the most common symptoms are gradual increases of pain and an eventual limitation in mobility.
Surgery
Surgery might be needed to treat rotator cuff tears if there is severe pain, very little mobility, non-surgical treatments don't work or the muscles or tendons are completely torn, according to the AAOS.
Non-Surgery Treatments
Non-surgical options that may be used to treat a rotator cuff tear are rest, anti-inflammatory medication and physical therapy, or immobilizing the arm and shoulder with a sling.
