1. A facet guide device for accessing and guiding at least one fixation device to a cervical spine via a posterior approach, the device comprising an elongated body comprising:

  • a distal portion comprising a chamfered or beveled end portion configured for insertion in a facet joint of the cervical spine; and

    a proximal shaft portion extending from the distal portion, and having a first set of opposing sides extending at least a portion of a length of the elongated body, and a shaped proximal end,wherein the shaped proximal end maximizes accessible lateral mass area,wherein at least one side of the first set of opposing sides has a complementary shape to at least one lumen of a slidable guide device comprising at least two lumens coupled together and having parallel and distinct central longitudinal axes, the slidable guide device configured to receive and guide a fixation device to the cervical spine, andwherein the elongated body of the facet guide device decreases in height from the shaped proximal end to the distal portion along the length of the elongated body.
