AB Hip  dislocations  are  true  orthopedic  emergencies  that  the  Emergency  Physician  must  be  capable  of  reducing.  Neurovascular  damage  to  the  hip  and  leg  is  a  known  consequence  of  hip  dislocations.  Avascular  necrosis  (AVN)  may  occur  in  up  to  20%  of  patients  with  a  hip  dislocation,  with  some  studies  showing  that  AVN  following  a  hip  dislocation  occurs  in  a  time-dependent  fashion.  In  other  words,  the  longer  a  hip  is  dislocated,  the  higher  the  incidence  of  AVN.1  Dislocation  for  more  than  6  hours  almost  universally  results  in  AVN.2-4  A  hip  dislocation  can  be  diagnosed  clinically  with  the  help  of  radiologic  studies.5  The  advantages  of  plain  films  and  computed  tomography  (CT)  scans,  over  the  use  of  ultrasonography,  are  to  identify  associated  fractures.
