Posterior sternoclavicular dislocation

Abstract

Posterior sternoclavicular joint dislocation is an extremely rare condition, usually seen in males after high energy concussion. Potentially lethal complications may appear in 25% of cases, due to compression of mediastinic structures. Radiological diagnose may be difficult, why computed tomography is usually used to determine type and grade of displacement and relation with mediastinic structures. We present a case of a 14 year-old woman who presented a posterior sternoclavicular dislocation due to a fall while playing karate.
