What are Bursae?

• Flattened sacs lined by synovial membrane.

• The synovial membrane produces lubricating fluid.

• Bursae serve to prevent friction between muscles and tendons.

Bursae of the Pectoral Girdle:

• The subscapular bursa is beneath the subscapularis tendon (between the tendons of the subscapularis muscle and the scapular neck).

• The subacromial bursa is the largest pectoral bursa. It is important in deltoid muscle movement.

• The sub-deltoid bursa communicates with the subacromial bursa.

What is Bursitis?

• Bursitis is an inflammation of the bursal membrane.

Shoulder Dislocation:

Shoulder dislocation commonly occurs in the inferior glenohumeral portion. It is due to the opening in the inferior capsule by the muscle tendon and weakness of the ligament itself at this point.
