The coracoclavicular ligament connects the clavicle to the coracoid process of the scapula. [1] It is not part of the acromioclavicular joint articulation, but is usually described with it, since it keeps the clavicle in contact with the acromion. It consists of two fasciculi, the trapezoid ligament in front, and the conoid ligament behind. [2]
There is a 2- to 3-fold increase in the coracoclavicular distance, causing such a severe displacement that the clavicle almost pierces the skin. [11] The humerus and scapula drop without having the clavicular strut to lift them, which manifests as a severely drooping shoulder. [ 11 ]
The conoid ligament is the posterior and medial fasciculus of the coracoclavicular ligament. It is formed by a dense band of fibers, conical in form, with its base directed upward. It is formed by a dense band of fibers, conical in form, with its base directed upward.
The coracoacromial ligament may impinge and compress rotator cuff muscle or tendon. [3] It may be damaged during a shoulder injury. [4]The attachment of the coracoacromial ligament may be moved from acromion to the end of the clavicle when reconstructing the acromioclavicular joint.
the inferior surface has a ridge called the trapezoid line and a tubercle; the conoid tubercle for attachment with the trapezoid and the conoid ligament, part of the coracoclavicular ligament that serves to connect the collarbone with the coracoid process of the scapula. Parts of clavicle
The shoulder consists of a ball-and-socket joint formed by the humerus and scapula and their surrounding structures - ligaments, muscles, tendons - which support the bones and maintain the relationship of one to another.
The procedure is done to replace the coracoclavicular ligaments with the coracoacromial ligament. [2] There is currently no "gold standard" surgery to repair acromioclavicular separations, and many surgeries have been created. However, this is one of the more common fixes. The original surgery is described as follows.
While this muscle prevents dislocation in the joint, strong forces tend to break the clavicle instead. The acromioclavicular joint, the joint between the acromion process on the scapula and the clavicle, is similarly strengthened by strong ligaments, especially the coracoclavicular ligament which prevents excessive lateral and medial movements ...
