RationaleAsymmetrical bilateral sternoclavicular joint (SCJ) dislocation consists of posterior SCJ dislocation on one side and anterior SCJ dislocation on the other side. This is an extremely rare injury and only a few cases have been reported in the literature. If not been diagnosed timely and accurately, asymmetrical bilateral SCJ dislocation can be life-threatening.Patients ConcernsWe experienced a patient who has a life-threatening posterior dislocation of right SCJ and anterior dislocation on the left SCJ combined with bilateral clavicular fracture after a traffic accident.DiagnosesA computed tomography (CT) scan with three-dimensional reconstructions of SCJ showed potentially life-threatening posterior dislocation of right SCJ and anterior dislocation on the left SCJ combined with bilateral clavicular fracture.InterventionsBecause of failed attempts at closed reduction, electively surgical intervention was made. We repaired the ruptured joint capsule and ligaments and fixed bilateral SCJ by Kirschner wire during the operation.OutcomesThree-dimensional CT scans confirmed bilateral SCJ reduction and alignment after operation 1 week as well as at the 2-month follow-up.LessonsSCJ dislocation is an extremely rare and life-threatening injury. The aim of the operation is to repair the ruptured joint capsule and its ligaments and to fix the dislocated joints.
