What is the function of the coracoclavicular ligaments?
The coracoclavicular ligament, as described above, serves to connect the clavicle and the coracoid process of the scapula. Its two-component structure allows for proper apposition of the acromion and the clavicle while preventing vertical displacement of the scapula with respect to the clavicle.
What is ossification of the coracoclavicular ligament?
Isolated ossification of the coracoacromial ligament is a rare finding, and in this case most likely secondary to previous trauma. Calcification of this ligament is most often due to trauma or renal failure, and if sometimes referred to as a hook osteophyte.
What is the result of a torn coracoclavicular ligament?
Type II injuries involve a complete tear of the AC ligaments and a sprain or partial tear of the coracoclavicular (CC) ligaments. This causes a tender AC joint, often with significant swelling (figure 2).
What is the purpose of the coracohumeral ligament?
Function. The coracohumeral ligament strengthens the upper part of the joint capsule of the shoulder joint.
Where is the coracoclavicular ligament?
shoulder
The coracoclavicular ligament is a ligament of the shoulder. It connects the clavicle to the coracoid process of the scapula. The left shoulder and acromioclavicular joints, and the proper ligaments of the scapula.
What does the coracoclavicular ligament consist of?
It consists of two fasciculi, called the trapezoid and conoid ligaments: The Trapezoid Ligament (ligamentum trapezoideum), the anterior and lateral fasciculus, is broad, thin, and quadrilateral: it is placed obliquely between the coracoid process and the clavicle.
What does the coracohumeral ligament limit?
Background. Contracture of the coracohumeral ligament is reported to restrict external rotation of the shoulder with arm at the side and restrict posterior-inferior shift of the humeral head. The contracture is supposed to restrict range of motion of the glenohumeral joint.
What is a Coracoclavicular joint?
Coracoclavicular joint (CCJ) is a rare anomalous joint occasionally found between the coracoid process of scapula and the conoid tubercle of clavicle. The articulation has been extensively studied by means of anatomical, osteological and radiological investigations.
What is Coracoclavicular joint?
Is the coracoclavicular ligament strong?
The coracoclavicular ligaments are strong supports between the lateral end of the clavicle and the coracoid process of the scapula. On each side, they are sited medially and inferior to the acromioclavicular joints.
