What does the coracoacromial ligament limit?
Together with the inferior aspect of the acromion and the coracoid process of the scapula, the CAL forms the coracoacromial arch that acts to limit superior displacement of the humeral head from the glenoid (Figure 1). Superiorly, the CAL is continuous with the fascia of the deltoid at its insertion along the acromion.
What does the coracoacromial ligament resist?
The coracoacromial ligament (CAL) connects the acromion and coracoid process of the scapula, forming an osseoliga- mentous static restraint to superior humeral head displace- ment.
What structure passes under the coracoacromial ligament?
The coracoacromial ligament is a strong triangular ligament between the coracoid process and the acromion. It protects the head of the humerus….

What is coracoacromial ligament release?
At 0° and 30° of abduction, release of the coracoacromial ligament resulted in a significant increase in glenohumeral joint translations, in both the anterior and inferior directions. The results of this study suggest that the coracoacromial ligament has a role in static restraint of the glenohumeral joint.
What does the Costoclavicular ligament do?
The costoclavicular ligament reinforces the inferior aspect of the joint, acting to limit clavicle elevation and anteroposterior movement.
What is the function of Costoclavicular ligament?
The costoclavicular ligament or rhomboid ligament (a.k.a. Halsted’s ligament 2) is the major stabilizing factor of the sternoclavicular joint and is the axis of movement of the joint.
What does the Coracohumeral ligament do?
Function. The coracohumeral ligament strengthens the upper part of the joint capsule of the shoulder joint.
Is the coracoacromial ligament part of the acromioclavicular joint?
This combined ligament is the primary support ligament of the AC Joint. The Coracoclavicular ligaments run from the coracoid process to the underside of the clavicle, near the AC Joint.
What is the purpose of the coracohumeral ligament?
What is costoclavicular?
The costoclavicular space is the anterior portion of the superior thoracic aperture, between the clavicle and first rib. The subclavian vessels and brachial plexus pass though the space related to the scalene muscles.
What is coracoclavicular ligament?
The coracoclavicular ligament is a ligament of the shoulder. It connects the clavicle to the coracoid process of the scapula.
