Name
- Coracoclavicular Bursa
- Supracoracoid bursa
- Coracoclavicular ligament bursa
- Conoid–trapezoid bursa
- Bursa of the coracoclavicular ligaments
- Subcoracoid–coracoclavicular bursa
- Coracoid–clavicular bursa
General
- Found within the angle separating the trapezoid/conoid segments of the coracoclavicular ligament[4]
- Surrounded by various amounts of fibro fatty tissue
- Smaller discrete bursae around the coracoid process can be found adjacently
- One of the minor bursa of the shoulder
Anatomic Variance
- Bursa may be absent and the trapezoid/conoid ligaments are separated by adipose tissue
Function
- Permits frictionless movement between the coracoclavicular ligament and the clavicle
Clinical Significance
- Calcific coracoclavicular bursitis
- Septic Bursitis
