Acromioclavicular Joint

Acromioclavicular Joint

The structure indicated is the acromioclavicular joint. The shoulder joint complex consists of the three joints:
  1. Glenohumeral joint
  2. Acromioclavicular joint
  3. Sternoclavicular joint
The acromioclavicular joint is formed between the acromion of the scapula and the clavicle. It is a small synovial joint that is stabilised by the following ligaments:
  • Acromioclavicular ligament (consists of superior and inferior parts)
  • Coracoclavicular ligaments
The coracoclavicular ligaments consist of two parts:
  • Trapezoid ligament
  • Conoid ligament
