Shoulder pain
Shoulder pain is "unilateral or bilateral pain of the shoulder. It is often caused by physical activities such as work or sports participation, but may also be pathologic in origin."[1]
Cause/etiology
Shoulder impingement syndrome
Shoulder impingement syndrome is "compression of the rotator cuff tendons and subacromial bursa between the humeral head and structures that make up the coracoacromial arch and the humeral tuberosities. This condition is associated with subacromial bursitis and rotator cuff (largely supraspinatus) and bicipital tendon inflammation, with or without degenerative changes in the tendon. Pain that is most severe when the arm is abducted in an arc between 40 and 120 degrees, sometimes associated with tears in the rotator cuff, is the chief symptom."[2]
Diagnosis
History and physical examination
The history and physical examination has limited ability with no finding having more than 80% sensitivity to diagnose the causes of shoulder pain according to a systematic review of the topic.[3]
