Types of sprains (6 grades)
Grade 1 is a simple sprain to the AC joint.
Grade 2 involves rupture of the AC ligament.
Grade 3 is a rupture of both AC and CC ligaments which often results in a superior displacement.
Grade 4 is the same as grade 3 but it involves posterior displacement.
Grade 5 is a superior displacement, to a greater degree than grade 3.
Grade 6 involves full rupture of both AC and CC ligaments with the clavicle being displaced inferiorly.

Removal of the end of the clavicle
Damage to the nerves and vessels in the clavicular area
Structures involved
The AC ligament =Acromioclavicular ligament
This is formed by the outer end of the collar bone and the acromion process of the shoulder blade
The CC ligament =Coracoclavicular ligament
This joins the clavicle to the coracoid process
