acromioclavicular joint injury

(redirected from acromioclavicular joint dislocation)

acromioclavicular joint injury

A disruption of the articulation formed between the acromion process and the clavicle, which may be accompanied by tearing of ligaments.
 
Sports involved
Football, wrestling, equestrianism, hockey.
 
Clinical findings
Pain at the top of the shoulder, decreased range of movement, splinting with arm held to the side; severe injury may be accompanied by a “lump” on the top of the shoulder.
 
Grading
Grade I—partial tear of the acromioclavicular ligament.
Grade II—complete tear of the acromioclavicular ligament and partial tear of the coracoclavicular ligament, accompanied by subluxation or partial displacement.
Grade III—complete disruption of the joint.

Management
Ice may alleviate pain and inflammation; grades I and II: use of a sling for pain; grade III may require open reduction and internal fixation, though there may be some disinclination to perform this manouevre for a non-break.

Mechanism
Direct downward blow to the tip of the shoulder.
