Acromioclavicular Joint Sprains
Diagnosis of Acromioclavicular Joint Sprains
X-rays Anteroposterior x-rays of both sides of the clavicle are taken. Acromioclavicular joint sprains are classified based on x-ray findings: Type I:No joint disruption Type II:Subluxation with some overlap of the clavicle and acromion Type III:Complete joint dislocation, usually because the coracoclavicular ligament is torn Type IV:Posterior displacement of the distal clavicle Type V:Superior displacement of the distal clavicle Type VI:Inferior displacement of the distal clavicle Types IV, V, and VI are variants of type III.
