coracohumeral ligament

The coracohumeral ligament is a fibrous structure that contributes to the stability of the glenohumeral joint by combined action with the rotator cuff muscles, superior glenohumeral ligament, and capsule.

What is the main function of the coracohumeral ligament?

Function. The coracohumeral ligament strengthens the upper part of the joint capsule of the shoulder joint.

What motion does the coracohumeral ligament stabilize?

Various stretching procedures have been reported for the coracohumeral ligament. Burkart et al[11] reported that the coracohumeral ligament restricted the range of motion of external rotation of the glenohumeral joint at 0 degrees of elevation and 50 degrees of abduction.

What joint does the coracohumeral ligament support?

The coracoclavicular (CC) ligament serves as the primary support for acromioclavicular (AC) ligament. Together, these stabilize the acromioclavicular joint, which is one of the major shoulder joints.

What type of joint is a Coracohumeral joint?

The glenohumeral joint is structurally a ball-and-socket joint and functionally is considered a diarthrodial, multiaxial, joint.

What is thickened coracohumeral ligament?

A thickened coracohumeral ligament at the rotator interval has been reported as one of the most specific manifestations of frozen shoulder. It covers wider portions of the subscapularis tendon, supraspinatus tendon, and infraspinatus tendon than previously reported.

Where is coracohumeral ligament?

Anatomical Parts

The coracohumeral ligament is a broad band which strengthens the upper part of the capsule. It arises from the lateral border of the coracoid process, and passes obliquely downward and lateralward to the front of the greater tubercle of the humerus, blending with the tendon of the Supraspinatus.

Is coracohumeral ligament a capsular ligament?

In its normal state the coracohumeral ligament usually appears as a capsular reflection on the coracoid base, and though it courses toward the superior aspect of the intertubercular groove, it is not a true ligamentous structure.

What is the role of the coracoacromial Arch?

The coracoacromial veil interacts with the structures of the coracoacromial arch and glenohumeral capsule to limit inferior humeral translation. Likewise, the coracoacromial ligament and the acromian serve to limit superior translation. Attempts to preserve these structures may help improve surgical outcomes.

What does the coracoacromial arch prevent?

a protective arch formed by the smooth inferior aspect of the acromion and the coracoid process of the scapula with the coracoacromial ligament spanning between them. This osseoligamentous structure overlies the head of the humerus, preventing its upward displacement from the glenoid fossa.

What causes subacromial impingement?

The causes of this impingement include: Your tendon is torn or swollen. This can be due to overuse from repetitive activity of the shoulder, injury or from age-related wear and tear. Your bursa is irritated and inflamed.

How long does it take for a torn ligament in the shoulder to heal?

Moderate sprains or strains may take as long as six to eight weeks before you can resume day-to-day shoulder activities. Severe strains or sprains may feel better within four to six weeks, but they need three to five months of rehabilitation before resuming full shoulder activity.

What does AC joint pain feel like?

Some common symptoms include: Pain at the top of the shoulder that may spread to the side of the neck. Snapping or clicking sound as you move your shoulder. Limited range of motion, such as when lifting up your arm.

How do you heal a torn ligament in your shoulder?

What are nonsurgical treatments for rotator cuff tears?
An arm sling and rest to give your shoulder time to heal. Nonsteroidal anti-inflammatory drugs (NSAIDs) to minimize pain and swelling.Physical therapy to learn strengthening and stretching exercises.Steroid injections to ease pain and swelling.

What attaches to coracoid process?

The coracoid process serves as the attachment site for several muscles. The pectoralis minor is attached to the medial aspect of the coracoid. The coracobrachialis is attached to the tip of the process on the medial side, and the short head of the biceps is attached to the tip of the process on the lateral side.

What are the 8 movements of the shoulder?

Overview. The human shoulder is the most mobile joint in the body. This mobility provides the upper extremity with tremendous range of motion such as adduction, abduction, flexion, extension, internal rotation, external rotation, and 360° circumduction in the sagittal plane.

What is coracoid process?

The coracoid process is a hook-shaped bone structure projecting anterolaterally from the superior aspect of the scapular neck.

What are the 3 glenohumeral ligaments?
