What is the purpose of the coracoacromial ligament?
The coracoacromial ligament (CAL) connects the acromion and coracoid process of the scapula, forming an osseoligamentous static restraint to superior humeral head displacement.
What passes under the coracoacromial ligament?
Supraspinatus and the superior aspect of shoulder joint The tendon of the muscle passes deep to the coracoacromial ligament to gain insertion to the greater tubercle and the superior aspect of the capsule of the shoulder joint. It is supplied by the suprascapular nerve.
What are the components of Coracoacromial Arch?
Structures located within the coracoacromial arch include:
- subacromial-subdeltoid bursa.
- supraspinatus tendon.
- superior part of the infraspinatus tendon.
- rotator cuff interval. long head of biceps tendon. coracohumeral ligament. superior glenohumeral ligament.
What are the functions of the Coracoclavicular ligament?
The function of the coracoclavicular ligament is to allow complex shoulder movement without separation of the scapula from the clavicle. Major muscles that cause movement around these structures include the serratus anterior, trapezius, teres major, rhomboid major, rhomboid minor, and triceps brachii (long head).
What is odd about the coracoacromial ligament?
On the undersurface of the acromion is a very odd, rubbery connective tissue at the insertion of the coracoacromial ligament. First, a soft tissue resector to remove the coracoacromial ligament and the soft tissue on the undersurface of the acromion down to bone, and second, a bony burr.
What is the Coracoacromial?
Coracoacromial ligament: one of the ligaments of the shoulder. Ligaments are bands of tough fibrous connective tissue that connect bones or cartilage. The coracoacromial ligament joins two parts of the shoulder blade (scapula), connecting the acromion to the coracoid process.
What is odd about the Coracoacromial ligament?
What is a coracoacromial Arch?
Coracoacromial arch is an osteofibrous structure resulting from the continuity of the acromion, coracoacromial ligament, and coracoid process with each other (13). In case of lower localization of coracoacromial arch, the pressure on the rotator cuff may increase (13).
How coracoacromial arch is formed?
cor·a·co·a·cro·mi·al arch 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.
Where does the Coracoclavicular ligament attach?
It is attached, below, to the upper surface of the coracoid process; above, to the oblique ridge on the under surface of the clavicle. Its anterior border is free; its posterior border is joined with the conoid ligament, the two forming, by their junction, an angle projecting backward.
What type of joint is the Coracoacromial ligament?
synovial articulation
Gross anatomy The coracoclavicular joint represents a true synovial articulation between the conoid tubercle of the clavicle and the superior surface of coracoid process of the scapula. This accessory articulation may be found either unilaterally or bilaterally.
