What is subcoracoid bursa?

What is subcoracoid bursa?

The subcoracoid bursa is located between the anterior surface of the subscapularis and the coracoid process. It extends caudal to the tendon of the coracobrachialis and the short head of the biceps. This bursa does not normally communicate with the glenohumeral joint but may communicate with the subacromial bursa [1].

What is Sasd bursitis?

The subacromial-subdeltoid bursa (SASD) is a potentially pain-sensitive structure of the glenohumeral joint. Along with the rotator cuff tendons, it has been implicated as a primary pathology in painful shoulder conditions of overhead athletes (eg swimmers, weightlifters, gymnasts, tennis players etc).

What is normal thickness of subacromial bursa?

Conclusions: Normal SA/SD bursa fluid is rarely thicker than 2 mm and tends to be located posteriorly. An abnormal amount of fluid is present when the thickness exceeds 3 mm, fluid is present medial to the ACJ, and fluid is seen in the part of the bursa anterior to the humerus.

Does subcoracoid bursa communicate with joint?

A bursa is a synovial lined potential space which reduces friction at tendon-tendon and tendon-bone interfaces. The only other such structure communicating normally with the joint is the biceps tendon sheath. The subacromial bursa and the subcoracoid bursa do not communicate with the joint under normal circumstances.

What does subcoracoid mean?

Medical Definition of subcoracoid : situated or occurring under the coracoid process of the scapula a subcoracoid dislocation of the humerus.

What is subcoracoid impingement?

Subcoracoid impingement is an unusual form of shoulder impingement, and results from narrowing of the coracohumeral interval (space between the tip of the coracoid and the humerus).

Is subacromial bursitis serious?

Septic bursitis in the shoulder is unusual but can be serious. People with septic shoulder bursitis will experience the same symptoms described above and may also feel tired, feverish, and sick, and notice warmth and redness at the shoulder. The pain level will also be much higher.

What causes thickening of the subacromial bursa?

Often there is an initial injury that sets off the inflammation. After that, the problem can spiral into a worse condition. This inflammation causes a thickening of the tendons and bursa. The thickening then takes up more space, pinching on the tendons and bursa even more.

How many Bursas are in the shoulder?

Within the shoulder, there are 8 bursae. This number makes the shoulder the place where more bursae are than any other bodily region. The primary shoulder bursae are the subcoracoid bursa, subacromial bursa, subdeltoid bursa, and subscapular bursa.

Where is the infraspinatus bursa located?

The infraspinatus bursa is located between the tendon of the infraspinatus muscle and the caudal eminence of the greater tubercle of the proximal humerus.

What causes Subcoracoid impingement?

For example, rotator cuff tears or degeneration or an unusual shape or length of the coracoid bone can lead to coracoid impingement. Calcium build up in the subscapularis bone or the formation of a ganglion cyst can also cause impingement in this area.

Where is the subcoracoid bursa located?

Subcoracoid bursa. The subcoracoid bursa is located anterior to subscapularis and beneath the coracoid process and extends caudal to the conjoined tendons of coracobrachialis and short head of biceps brachii . Fluid in the subcoracoid bursa does not normally communicate with the glenohumeral joint but may communicate with the subacromial bursa.

Can you see subcoracoid bursa on MRI?

Objective: The subcoracoid bursa, a bursa anterior to the shoulder joint, can be identified on MR images. Awareness of the MR appearance and location of this bursa, which can connect with the subacromial-subdeltoid bursa, enables appropriate diagnosis in patients with shoulder pain.

What are the subcoracoid and superior subscapularis?

When containing effusions, these structures, the subcoracoid bursa and superior subscapularis, are revealed on MR imaging (Fig. 1). The subcoracoid bursa is located between the anterior surface of the subscapularis and the coracoid process. It extends caudal to the tendon of the coracobrachialis and the short head of the biceps.

What are the symptoms of distention of the subcoracoid bursa?

Some authors have suggested that distention of the subcoracoid bursa alone may produce symptoms 4, 10, characterized clinically by anterior shoulder pain inferior to the coracoid process 11.
