Treatment of posterior epiphyseal disruption of the medial clavicle with a modified Balser plate.

Background: Acute posterior dislocation of the sternoclavicular joint is a rare but dangerous injury that is often difficult to diagnose. Because of late closure of the medial clavicular epiphysis, epiphyseal disruption must be taken into consideration in patients up to 25 years of age with an apparent diagnosis of posterior sternoclavicular dislocation. We developed a novel method of treating epiphyseal disruptions with a modified Balser plate.
