Grade 3—Involves tearing of the joint covering (capsule) and ligaments connecting the shoulder blade (scapula) and collar bone (clavicle). Causes a mild to moderate permanent bump over the top of the shoulder at the AC joint. Pain typically lasts 4-8 weeks. Surgery is usually not required.
Grade III Injury: Pain is present around the joint and in the area of the coracoclavicular ligaments. Swelling is present. As the joint moves, a popping sound may occur. There is shoulder deformity and a bump on the top of the shoulder.
The acromioclavicular joint is a diarthrodial joint defined by the lateral clavicle articulating with the acromion process as it projects anteriorly off the scapula. The AC joint is a plane type synovial joint, which under normal physiological conditions allows only gliding movement.
The acromioclavicular, or AC, joint is a joint in the shoulder where two bones meet. One of these bones is the collarbone, or clavicle. The second bone is actually part of the shoulder blade (scapula), which is the big bone behind the shoulder that also forms part of the shoulder joint.
A type III separation involves injury to both the AC joint ligaments the CC ligaments. This results in complete separation between the acromion and clavicle, and treatment for this type is controversial. Some authors have reported good results with non-operative treatment of type III injuries.
Most people do well without surgery. The severe injury (Grade 3) can be treated either nonoperatively or operatively. Non-operative treatment involves immobilisation in a sling for two to three weeks followed by a course of physiotherapy.
The acromioclavicular (AC) joint is formed by the cap of the shoulder (acromion) and the collar bone (clavicle). It is held together by strong ligaments (figure 1). The outer end of the clavicle is held in alignment with the acromion by the acromioclavicular ligaments and the coracoclavicular (CC) ligaments.
Description. The Acromioclavicular Joint, or AC Joint, is one of four joints that comprises the Shoulder complex. The AC Joint is formed by the junction of the lateral clavicle and the acromion process of the scapula and is a gliding, or plane style synovial joint.

If the distance between the two bones is between increased between 25 and 100% it is a grade 3 and if it is more than that it is a grade 5. A grade 4 ac separation is one where there is significant posterior movement of the clavicle relative to the acromion.
A shoulder separation is not the same as a dislocation. In a dislocation, your upper arm bone (the humerus) pulls out of the shoulder joint. Shoulder separations are common, especially in active young adults. Your shoulder blade connects to your upper arm bone and to your collarbone with ligaments.
The medical term for the shoulder socket is glenoid cavity. This ball-and-socket construction allows for circular movement of the arm. Acromioclavicular joint (AC joint). The acromioclavicular joint is located where the clavicle (collarbone) glides along the acromion, located at the top of the shoulder blade.
