Definition of Rotator cuff tendinitis
Rotator cuff tendinitis is an inflammation (irritation and swelling) of the tendons of the shoulder.
Causes, incidence, and risk factors
The shoulder joint is a ball and socket type joint where the top part of the arm bone (humerus) forms a joint with the shoulder blade (scapula). The rotator cuff holds the head of the humerus into the scapula.
Signs and tests
A physical examination may reveal tenderness over the shoulder. Pain may occur when the shoulder is raised overhead. There is usually weakness of the shoulder when it is placed in certain positions.
Treatment involves resting the shoulder and avoiding activities that cause pain. Ice packs applied to the shoulder and nonsteroidal anti-inflammatory drugs will help reduce inflammation and pain.
Most people recover full function after a combination of medications, physical therapy, and steroid injections. For patients with tendinitis and a bone spur, arthroscopic surgery is usually successful in restoring them to their pre-injury level of activity.
