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. [5] [6] This often fails. [5]
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.
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] This injury generally requires surgery. [5]
Modern variations of the procedure may use additional fixation methods to better stabilize the distal clavicle end as the original construction is rather weak compared to the unharmed shoulder. Even with these modifications, the modern surgeries do not match intact coracoclavicular ligament strength in cadaveric testing. [3]
The acromioclavicular joint provides the ability to raise the arm above the head. This joint functions as a pivot point (although technically it is a gliding synovial joint), acting like a strut to help with movement of the scapula resulting in a greater degree of arm rotation.
The clavipectoral fascia (costocoracoid membrane; coracoclavicular fascia) is a strong fascia situated under cover of the clavicular portion of the pectoralis major.. It occupies the interval between the pectoralis minor and subclavius, and protects the axillary vein and artery, and axillary nerve.
It forms two bands [3]: 908 - an anterior one and a posterior one - that insert into the lesser and greater tubercles of the humerus, respectively. [ 4 ] The two bands of the CCL blend with the joint capsule; [ 3 ] : 908 the ligament is intimately united with the capsule by its posterior and inferior border, but its anterior and superior border ...
[2] It is often caused by a fall onto a shoulder, outstretched arm, or direct trauma. [1] [3] The fracture can also occur in a baby during childbirth. [1] The middle section of the clavicle is most often involved. [3] Diagnosis is typically based on symptoms and confirmed with X-rays. [2]
