AB The  dorsal  root  ganglion  (DRG)  contains  the  cell  bodies  of  first-order  sensory  neurons,  each  of  which  project  an  axon  from  a  peripheral  receptor,  and  centrally  to  the  posterior  horn  of  the  spinal  cord,  where  they  synapse  with  second-order  neurons.There  is  one  DRG  for  each  spinal  nerve  root  supplying  the  posterior  aspect  of  the  head,  the  trunk  and  the  extremities;  in  the  face,  this  function  is  carried  out  by  the  trigeminal  ganglion.Unless  prevented  or  treated,  injury  to  the  DRG  often  leads  to  the  development  of  a  chronic  neuropathic  pain  state.  Injection  procedures  that  target  the  DRG  could  be  used  in  the  treatment  of  any  radicular  pain  syndrome,  such  as  primary  radicular  irritation,  postherpetic  neuralgia.
