AB  - The  hand  is  innervated  by  the  median,  ulnar,  and  radial  nerves.  Motor  function  of  the  median  nerve  can  be  screened  by  flexing  the  thumb  distal  phalanx  against  resistance,  the  ulnar  nerve  by  spreading  the  fingers  against  resistance,  and  the  radial  nerve  by  maintaining  extension  of  the  wrist  and  fingers  against  resistance.  Sensory  innervation  (Fig.  170-1)  is  best  screened  by  the  presence  of  normal  2-point  discrimination  (<6  mm).  Injuries  requiring  hand  surgery  consultation  are  listed  in  Tables  170-1  and  170-2.
