Where does the impingement of the AC joint occur?

The AC joint is compromised of the acromion bone from the shoulder and the collar bone (clavicle). Underneath the AC joint is the subacromial space that contains the rotator cuff tendons and bursa. AC joint impingement occurs when there is the narrowing of the subacromial space and puts the rotator cuff and bursa at risk for injury.

Where does the clavicle and the acromion meet?

As a result, where the clavicle meets the acromion is called the AC joint. Like most joints in the body where bones meet, there is cartilage between the two bones, which is the white tissue between bones that allows them to move on each other, like Teflon on two ball bearings.
