1. An implantable spinal fixation plate, comprising:
- an elongate central portion including at least one thru-bore formed therein and having proximal and distal ends that define a longitudinal axis extending therebetween, at least one of the proximal and distal ends including a notch formed therein; and
first and second branch portions that extend from opposed sides of the elongate central portion at an angle relative to the longitudinal axis of the elongate central portion, at least one of the branch portions including a mating edge formed thereon and extending substantially transverse to the longitudinal axis of the elongate central portion, the mating edge being opposed to the notch such that a guide device can engage the mating edge and the notch to align at least one pathway in the guide device with the at least one thru-bore formed in the elongate central portion.

Abstract
Disclosed herein are spinal fixation devices and tools for implanting the same. In one embodiment, an implantable spinal fixation plate and a guide device are provided and they include features that allow the two devices to removably mate to one another. As a result, the guide device can be used to position and hold the plate against bone while inserting drills, taps, awls, and other bone preparation devices through the guide device. The guide device can also be configured to allow fasteners to be inserted therethrough and into bone to attach the plate to bone.

15. A guide device, comprising:
a housing having at least one pathway extending therethrough between proximal and distal ends thereof, the distal end of the housing including at least one protrusion and at least one member that are adapted to interact with a spinal fixation plate in a deflectable manner to position the housing with respect to the spinal fixation plate such that the at least one pathway in the housing is aligned with at least one thru-bore formed in a spinal fixation plate. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A method of positioning a spinal fixation plate to the occiput, the method comprising:
-
connecting the spinal fixation plate to a guide device;
manipulating the drill guide to position the spinal fixation plate proximate the occiput;
positioning an instrument through the guide device and a bore in the spinal fixation plate; and
creating a hole in the occiput with the instrument. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35)
