Bursa of the Shoulder
Description
Name
- Bursa of the Shoulder
- Shoulder bursae
General
- Bursa of the shoulder girdle filled with synovial fluid
- They facilitate movement to reduce friction at tendon/tendon or tendon/bone interface
- Aka: subacromial-subdeltoid bursa
- Bursa within the shoulder which protects the space between the acromion and rotator cuff
- Largest of the bursa within the shoulder girdle
- Sits on the lateral aspect of the scapula
- Located between the superior glenohumeral ligament and middle glenohumeral ligament[4]
- Permits friction free movement between tendon of subscapularis, coracoid process and scapular neck
- Sits anterior to the subscapularis muscle, deep to the coracoid process
- Reduce friction between coracobrachialis, subscapularis, short head of the biceps tendon
- Refers to a cluster of major/minor bursa that allow for movement of the scapulothoracic joint
- Sits on lateral scapula, deep to tendon of infraspinatus
- Permits frictionless movement of the tendon of infraspinatus
- Found within the angle separating the trapezoid/conoid segments of the coracoclavicular ligament[5]
- Permits frictionless movement between the coracoclavicular ligament and the clavicle
Medial extension of subacromial-subdeltoid bursa
- In some literature, described as a separate bursa from the subacromial bursa
Clinical Significance
General
- Infraspinatus Bursitis
- Calcific coracoclavicular bursitis
