Shoulder impingement is a fairly common problem in adults. The soft tissues around the shoulder get pinched between two bones. This usually happens to a tendon or bursa. The bursa is the cushion that sits between the tendon and the bone.
When conservative treatment fails, surgery is an option to think about. The operation is called decompression. The doctor shaves away any bone spurs and cuts out part of the acromion. The acromion projects from the scapula (wing bone) to form the roof of the shoulder. By removing the end of this bone, pressure is taken off the soft tissues underneath.
This operation is usually very successful. Most patients regain motion and function. Pain is relieved allowing the patient to return to work and recreational activities.
