The eccentric dilators allow for dilation away from any
sensitive structures (e.g. posterior nerves). Slide the small
dilator (rounded tip first) over the neuromonitoring
probe or Kirschner Wire in the orientation of preferred
direction of dilation. Continue with the remaining two
dilators with the groove for the stimulation probe facing
the preferred direction of dilation (midline or eccen-
tric (1)).
Precaution:
Use fluoroscopy (lateral and AP) to de
termine location of dilators. Also ensure that dila
tors rest firmly against the vertebral body wall in
order to determine an accurate skin depth measure
ment. Keep downward pressure on the dilators until
the strong arm or universal arm has been fixed to
the retractor.
