Shoulder Impingement

What is shoulder impingement?

The rotator cuff tendons and bursa reside in the narrow space between the top of the upper arm bone (humerus) and the top of the shoulder blade (acromion). When the arm is relaxed at your side, there is enough space. But when the arm is moved away from the body, the space gets narrower.

In a healthy shoulder, this narrowing, or compression, does not cause any pain or irritation. In an unhealthy shoulder, this compression can cause irritation, resulting in pain and inflammation. The inflammation and swelling take up more space, causing symptoms to continue. This is called shoulder impingement.

Arthroscopy is a minimally invasive surgical procedure that allows your orthopedic surgeon access to the inside of your joint through several tiny incisions. Your physician can confirm your diagnosis and repair any injured tissue by using a camera and tools inserted into the joint space.
