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.

What causes primary impingement?

“Primary impingement syndrome” describes a process in which pain in the shoulder is caused by direct (or primary) mechanical rubbing of the rotator cuff tendon by surrounding bony structures. This contact occurs when the arm is in an overhead position and generally relieved while the arm is at the side.

What causes secondary shoulder impingement?

Secondary impingement results from a functional disturbance of centering of the humeral head, such as muscular imbalance, leading to an abnormal displacement of the center of rotation in elevation and thereby to soft tissue entrapment (1).

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).

What is coracoid syndrome?

Coracoid impingement syndrome is a less common cause of shoulder pain. Symptoms are presumed to occur when the subscapularis tendon impinges between the coracoid and lesser tuberosity of the humerus [7]. This causes tendinosis and pain in the soft tissues.

What is Subcoracoid bursitis?

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 a hip impingement?

Hip impingement, or femoroacetabular impingement (FAI), occurs when the femoral head (ball of the hip) pinches up against the acetabulum (cup of the hip). When this happens, damage to the labrum (cartilage that surrounds the acetabulum) can occur, causing hip stiffness and pain, and can lead to arthritis.

Can impingement syndrome be caused by trauma?

Shoulder impingement symptoms can develop with trauma or over time without cause. Common causes of shoulder impingement from trauma include falls and traction injuries. Shoulder impingement can be caused by repetitive overhead activities. Shoulder impingement syndrome is most common in an aging population.

What’s hip impingement?

What is Subscap?

Muscles. The subscapularis muscle originates at the subscapular fossa and inserts into the lesser tubercle of the humerus. The muscle internally rotates and adducts the humerus.

What causes fluid in Subcoracoid Bursa?

Fluid within the subacromial bursa is a well-established sign of a full thickness rotator cuff tear, so in cases where a communication between the subacromial and subcoracoid bursae exists, a full thickness supraspinatus tendon tear would result in fluid within both bursae.

What does Subcoracoid mean?

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