What is the AC joint? The AC joint is one of two joints that make up your shoulder. It’s where the acromion (the top part of your shoulder blade) meets your clavicle (collarbone). That’s where the AC joint gets its full name — the acromioclavicular joint.
acromioclavicular joint sprain, The acromioclavicular (AC) joint is the articulation between the two bones of pectoral girdle; the clavicle and scapula. It is a plane synovial joint, with flat articular surfaces which are approximately the same in size. There are several causes for AC joint pain, and treatment varies depending on what's making your shoulder hurt. The AC joint is where the acromion (the tip of your shoulder blade— scapula) meets your clavicle (collarbone). "AC" is short for "acromioclavicular," which describes those two bones.
acromioclavicular joint sprain, The acromioclavicular, or AC, joint is a joint in the shoulder where two bones meet. One of these bones is the collarbone, or clavicle. The second bone is actually part of the shoulder blade (scapula), which is the big bone behind the shoulder that also forms part of the shoulder joint. The acromioclavicular joint provides the ability to raise the arm above the head. This joint functions as a pivot point (although technically it is a gliding synovial joint), acting like a strut to help with movement of the scapula resulting in a greater degree of arm rotation. The Acromioclavicular Joint, or AC Joint, is one of four joints that comprises the Shoulder complex.
The AC Joint is formed by the junction of the lateral clavicle and the acromion process of the scapula and is a gliding, or plane style synovial joint. The acromioclavicular (ah-kro-mee-o-klah-vik-u-ler) joint, also called the AC joint, is located at the top of the shoulder where the clavicle (collarbone) and highest part of the scapula (shoulder blade) meet. Acromioclavicular joint arthritis (AC joint arthritis) is a condition that affects the joint between the collarbone (clavicle) and the acromion (Figure 1), a part of the shoulder blade. This small joint helps with shoulder movement, especially when lifting the arm overhead.
