Acromioclavicular joint anatomy in 3D
The acromioclavicular joint is where the outer end of the clavicle meets the acromion of the scapula, and it can be felt at the top of the shoulder. The ligaments around the joint and the coracoclavicular ligament just inside it hold the two bones together.
Frequently asked questions
Which bones form the acromioclavicular joint?
The acromioclavicular joint is formed by the clavicle and the scapula.
What type of joint is the acromioclavicular joint?
It is a plane joint: the two flat surfaces only glide a little against each other.
What movements happen at the acromioclavicular joint?
When the arm is raised overhead or the shoulder moves, the scapula glides and turns slightly against the clavicle at this joint.
