Abstract

Bipolar clavicular dislocation is simultaneous dislocation of both poles of the clavicle (mainly an anterior dislocation of the sternoclavicular joint and a posterior dislocation of acromioclavicular joint) and rarely reported. We report a case of bipolar claviclular dislocation after a seat belt injury and describe its presumed mechanism and treatment with a review of literature.
Key words: Clavicle, Bipolar dislocation, Seat belt injury

Injury mechanism. Direct force on the posterolateral aspect of acromion or on the anterolateral aspect of distal clavicle may induce posterior dislocation of acromioclavicular joint, and torsional force of the trunk may provoke a horizontal abduction force along the injured clavicle consequently, anterior dislocation of sternoclavicular joint occur.
