What is Shoulder Impingement Syndrome?


The 3rd most common complaint we observe in orthopedic practice is shoulder pain. The most common cause of shoulder pain is shoulder impingement syndrome. 50% of patients with shoulder pain have impingement syndrome. The patient feels pain in his shoulder when he raises his arm.


The main reason is the narrowing of the subacromial space. The subacromial space consists of the distance between the coracoacromial arch and the humeral head. In impingement syndrome, the soft tissues between the roof of the shoulder and the head of the humerus are compressed. The average subacromial distance at rest is 11 mm (Normal value is 7-14 mm).
