What are symptoms of rotator cuff disease?
The most common symptom of rotator cuff disease is shoulder pain. The pain is often noticed gradually and may be first noticed even a day after the actual event which may have caused the injury. Sometimes, a sudden pain occurs during a sport activity. The pain is usually located to the front and side of the shoulder and is increased when the shoulder is moved away from the body. The pain is usually noted to be more intense at nighttime and sometimes increases when lying on the affected shoulder. The pain can diminish range of motion and movement of the arm. The inflammation from the rotator cuff disease and the lack of movement due to pain can result in a frozen shoulder. There can also be tenderness in the area of the inflamed tendons of the injured rotator cuff.
People with rotator cuff disease usually find it difficult to lift the arm away from the body fully. If the rotator cuff disease involves severe tears of the rotator cuff tendons, it can be impossible for the patient to hold the arm up because of pain and decreased function of the tendons and muscles.
How is rotator cuff disease diagnosed?
Rotator cuff disease is suggested by the patient's history of activities and symptoms of pain in the shoulder described above. In making a diagnosis, the doctor can observe increased pain with certain movements of the shoulder. The pain is due to local inflammation and swelling in the injured tendons of the rotator cuff. Additionally, with severe tendon tears of the rotator cuff, the arm falls due to weakness (positive drop sign) when moved away from the body.
The diagnosis of rotator cuff disease can be confirmed by radiology testing. Sometimes plain X-rays can show bony injuries, which suggest long-standing severe rotator cuff disease. An arthrogram involves injecting contrast dye into the shoulder joint to detect leakage out of the injured rotator cuff. The MRI is a noninvasive imaging test that uses a magnet and computer to produce fine images of the tissues of the shoulder. An MRI has the added advantage of providing more information than either X-ray or an arthrogram, especially if a condition other than rotator cuff disease is present.
