Grade I is slight displacement of the joint, and a badly stretched or partially torn AC ligament. It has the normal separation of <4 mm. Grade II is a partial dislocation of the AC joint with a complete disruption tear of the AC joint and a partial disruption of coracoclavicular ligament. The AC gap is >5 mm. Grades I and II never require ...
The coracoclavicular ligament is a strong stabilizer of the acromioclavicular joint. [2] It is also important in the transmission of weight of the upper limb to the axial skeleton . There is very little movement at the AC joint.

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 acromioclavicular joint, is the joint at the top of the shoulder. It is the junction between the acromion (part of the scapula that forms the highest point of the shoulder) and the clavicle. [1] It is a plane synovial joint. The acromioclavicular joint allows the arm to be raised above the head.
Subacromial impingement is not free of criticism. First, the identification of acromion type shows poor intra- and inter-observer reliability. [ 26 ] [ 27 ] Second, a computerized three-dimensional study failed to support impingement by any portion of the acromion on the rotator cuff tendons in different shoulder positions. [ 28 ]
