AB Dislocations  of  the  sternoclavicular  joint  (SCJ)  are  uncommon  due  to  the  strength  of  the  supporting  ligaments.  Anterior  dislocations  are  nine  times  more  frequent  than  posterior  dislocations.  Posterior  dislocations  are  clinically  more  important  due  to  the  potential  for  injury  to  underlying  structures.  SCJ  dislocations  typically  occur  from  motor  vehicle  crashes  and  sports  injuries.  Examination  findings  of  an  anterior  SCJ  dislocation  include  tenderness  and  prominence  of  the  proximal  clavicle  from  the  sternum.  The  arm  is  often  held  in  adduction.  Posterior  SCJ  dislocations  may  be  more  difficult  to  identify.  Pneumothorax,  great  vessel,  tracheal,  and  esophageal  injuries  often  accompany  posterior  SCJ  dislocations.  Pain  and  depression  of  the  medial  clavicle  relative  to  the  sternum  may  be  seen.  Superior  and  inferior  dislocations  may  also  be  seen.  CT  scan  through  the  SCJ  is  the  best  diagnostic  study  to  evaluate  this  injury.
