Sternoclavicular
Sternoclavicular joint is the articulation of the sternum (breastbone) and the clavicle (collarbone). It is a synovial joint, meaning it is surrounded by a thick, fluid-filled capsule. This joint is one of the four joints that complete the shoulder.
Anatomy[edit | edit source]
The sternoclavicular joint is composed of two bones: the sternal end of the clavicle and the manubrium of the sternum, and the first costal cartilage. The joint is covered by a capsule and supported by ligaments.
Ligaments[edit | edit source]
There are four ligaments that are associated with the sternoclavicular joint:
- Anterior sternoclavicular ligament
- Posterior sternoclavicular ligament
- Interclavicular ligament
- Costoclavicular ligament
Function[edit | edit source]
The sternoclavicular joint allows for a wide range of movements of the pectoral girdle, including protraction, retraction, elevation, depression, and slight rotation to aid in the movement of the shoulder.
Clinical significance[edit | edit source]
Injuries to the sternoclavicular joint are relatively rare due to its strength and deep location. However, when they do occur, they can be serious and potentially life-threatening. Conditions that can affect the sternoclavicular joint include:
- Sternoclavicular joint dislocation
- Sternoclavicular joint arthritis
- Sternoclavicular joint infection
