Subacromial Impingement is one of the most common causes of shoulder pain and is the subject of ongoing debate in the orthopaedic surgery community.

For most patients with impingement, nonsurgical treatment is successful. Surgical intervention is successful in patients who fail nonsurgical treatment.

Studies have shown that surgical intervention of debridement and open or arthroscopic acromioplasty, have been successful. The arthroscopic technique permits direct visualization of the shoulder joint and allows the surgeon to manage possible sources of impingement.
