AB Anterior  dislocations  account  for  more  than  90%  of  dislocations.  They  are  frequently  caused  by  falling  with  the  arm  externally  rotated  and  abducted,  causing  patients  to  present  with  the  affected  extremity  held  in  adduction  and  internal  rotation  due  to  pain.  The  acromion  becomes  prominent  with  loss  of  the  rounded  contour  of  the  deltoid.  Neurovascular  exam  of  the  upper  extremity  should  be  performed  to  rule  out  associated  injury,  most  commonly  of  the  axillary  nerve  (sensation  over  the  deltoid)  and  musculocutaneous  nerve  (anterolateral  forearm).  Vascular  injuries  are  rare.  Standard  radiographs  to  evaluate  for  fracture  should  include  AP  and  either  axillary  lateral  or  scapular  Y  views.
