This video highlights the pronounced excursion of the cervical spinal cord that occurs with patient ventilation during the cervical microinjection procedure. The dorsal root entry zone is just lateral to (below) the microinjection needle. The rigid outer cannula is withdrawn. The microinjection needle and flange are in position, flush to the spinal cord surface.
