Abstract: An aiming block fixation system for fixing an aiming block to a bone plate includes a bone plate having an outer surface and a bone-contacting surface for application to a bone. The aiming block has an upper surface, a lower surface engageable with the outer surface of the bone plate. A first angled aiming block bore extending from the upper surface to the lower surface along an axis which is at a non-zero degree angle to an axis of a bone plate hole. A locking element extends through the angled aiming block bore and the bone plate hole such that a central longitudinal axis of the locking element is oriented at a non-zero degree angle to the first axis, with the locking element including a radially outwardly extending camming arm selectively engageable with a camming surface of the first bone plate hole.

Abstract: A drill guide system for a bone plate having holes includes a guide block having at least two drill guide bores alignable with a bone screw receiving hole in a bone plate. A locking element extending through at least one drill guide block bore into the bone plate bone screw receiving hole, the locking element having a partially threaded bore portion and having a bifurcated tip surrounding the threaded bore portion. The bifurcated tip capable of engaging an inwardly extending protrusion formed on an internal wall of a bone screw receiving hole in the bone plate. An axially moveable threaded rod has a head for contacting an outer surface of the guide block and an end portion engaging a portion of the bore in the bifurcated tip of the locking element for separating sections of the bifurcated tip on axial movement of the rod prior to the head contacting the second surface of the drill guide block.
