A rotator cuff tear is a common injury that affects the muscles and tendons surrounding the shoulder joint. In this article, we examine the causes, symptoms, diagnosis, treatment, and prevention of rotator cuff tears. Rotator cuff tears can occur for a variety of reasons and can lead to pain, weakness, and limited range of motion.
Causes
A rotator cuff tear can be caused by acute trauma or degenerative changes in the shoulder joint. Common causes include:
-
A fall, sports injury, or motor vehicle accident that causes direct impact to the shoulder can tear the rotator cuff muscles or tendons.
-
Overuse: Repetitive overhead activities or excessive strain on the shoulder joint, which are common among athletes, manual workers, and individuals who paint, lift, or throw, can cause gradual rotator cuff tendons to wear and tear, resulting in tears.
-
Rotator cuff tears are more likely to occur in individuals over the age of 40 due to degenerative changes associated with aging, such as tendon degeneration, muscle weakness, and decreased blood supply to the rotator cuff.
Symptoms
Symptoms of rotator cuff tears vary depending on the severity and location of the tear.
-
Pain in the shoulder caused by overhead movements or activities that require lifting or reaching.
-
Symptoms include weakness and decreased strength in the affected shoulder, which makes lifting objects or combing hair difficult.
-
Having difficulty moving the shoulder joint, especially in certain directions or positions, due to pain and stiffness.
-
Stiffness in the shoulder joint, especially in the morning or after inactivity.
-
When moving the shoulder joint, there is a clicking, popping, or grinding sensation.
Diagnosis
Rotator cuff tears are usually diagnosed through a combination of medical history, physical examination, and imaging studies. Diagnostic procedures may include:
-
A healthcare provider will ask about symptoms, recent injuries, and activities that may have contributed to rotator cuff tears.
-
A thorough physical examination may reveal signs of rotator cuff tears, including range of motion, strength, stability, and tenderness.
-
An imaging study, such as X-rays, ultrasound, or magnetic resonance imaging (MRI), can be used to visualize the structures of the shoulder joint, determine the extent and location of the tear, and rule out other conditions such as arthritis or bursitis.
Treatment
Rotator cuff tears are treated according to their severity, location, chronicity, and the individual's age, activity level, and overall health.
-
To relieve shoulder pain, improve shoulder function, and strengthen the muscles surrounding the shoulder joint, conservative measures such as rest, activity modification, physical therapy, and anti-inflammatory medications may be recommended.
-
A rotator cuff tear may be relieved by corticosteroid injections into the shoulder joint, particularly in cases of acute or severe pain.
-
The surgical repair of large or symptomatic rotator cuff tears that do not respond to conservative treatment may be necessary. In order to reattach or reinforce the torn tendon and restore shoulder function, arthroscopic repair, open repair, or tendon transfer procedures may be used.
Prevention
Rotator cuff tears can be prevented by adopting lifestyle modifications and injury prevention strategies. Prevention strategies may include:
-
Preparing the shoulder muscles and tendons for activity and reducing injury risk can be achieved by performing proper warm-up exercises and stretching routines before engaging in physical activity or sports.
-
Exercises that strengthen the rotator cuff muscles and surrounding shoulder muscles can improve shoulder stability and prevent overuse injuries.
-
A proper lifting technique, avoiding repetitive overhead activities, and taking frequent breaks during activities that place strain on the shoulder joint can help minimize the risk of rotator cuff tears.
-
If you are new to exercise or sports, gradually increasing the intensity, duration, and frequency of your activities can help prevent overuse injuries and reduce the risk of rotator cuff tears.
