Impingement Syndrome / Rotator Cuff Tendonitis
Common Causes
Repetitive overhead use of the arm (tennis, hammering, gardening), frequent lifting, a fall on the shoulder or outstretched arm.
Symptoms
Pain in the shoulder or down the side of the arm. Usually fairly comfortable at rest. Pain with lifting the arm overhead, or sleeping on your side.
Physical Findings
Tenderness, positive 'impingement test'.
Workup
X-Rays. and physical examination, MRI (rarely).
Non-Operative Treatment
Rest, anti-inflammatory medication, physical therapy. Possibly a trial of a corticosteroid injection.
Surgical Treatment
Shoulder arthroscopy, with arthroscopic decompression
Comments
Generally curative with non-operative care when treated early. Arthroscopy is highly successful, with an early return to activities. Prolonged or worsening symptoms may be signs of a rotator cuff tear.
