Acromioclavicular joint

Anatomy and definition of the acromioclavicular joint.

Show transcript

Hello again everyone! It's Matt from Kenhub, and in this tutorial, we will discuss the anatomy and function of the acromioclavicular joint.

The acromioclavicular joint commonly called the AC joint is a synovial joint that is involved in the anatomy of the upper arm. On this image, you can see this joint highlighted in green. It connects the acromion of the scapula with the clavicle at its lateral end. This joint is stabilized by two sets of ligaments – the coracoacromial ligament and the coracoclavicular ligaments – which are all highlighted in green on both of these images.

This joint functions to allow anterior and posterior movement of the acromion during the protraction and retraction of the scapula, rotation during adduction and abduction of the shoulder, and the tilting of the acromion during adduction and abduction of the arm.
