Pain in the shoulder's acromioclavicular (AC) joint is a common problem that can be severe and persistent enough to interfere with your daily routine. There are several causes for AC joint pain, and treatment varies depending on what's making your shoulder hurt.
An acromioclavicular joint injury, otherwise known as a shoulder separation, is a traumatic injury to the acromioclavicular (AC) joint with disruption of the acromioclavicular ligaments and/or coracoclavicular (CC) ligaments.
The acromioclavicular ligament is a band of fibrous connective tissue that connects the acromion of the scapula to the lateral end of the clavicle. It plays an important role in the function of the shoulder by holding the acromioclavicular joint together.
Acromioclavicular joint (Articulatio acromioclavicularis) 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.
The AC joint is where the acromion (a part of the shoulder blade) connects to the clavicle (collar bone) at the top of the shoulder. This joint helps maintain the position of the shoulder and is very important for shoulder control, motion, and strength.
The acromioclavicular ligament is part of the acromioclavicular joint. It is divided into two parts: superior and inferior.
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.
