Abstract
A screw placement guide includes a first member having a first guide adapted to contact a first vertebral bone portion and a second member having a second guide adapted to contact a second vertebral bone portion. A clamping mechanism provided on one of the members clamps the first guide and the second guide to the vertebral bone portions. The first guide and the second guide are aligned in order to indicate how a fastener will be aligned when fastened between adjacent vertebrae. A driver engages clamping mechanism to clamp the two members together.
