Bone plate assembly provided with screw locking mechanisms

One embodiment of the present invention is directed to a bone plate assembly that includes a bone plate (12), bone screw(s) (14) received in aperture(s) in the bone plate, and screw fixation member(s) (18). The screw fixation member(s) may, alone or in conjunction with the bone plate, fix the bone screw(s) in place when such bone screw(s) are inserted in the aperture(s) in the bone plate. In one example (which example is intended to be illustrative and not restrictive) when the bone screw(s) have been received by the bone plate and inserted into bone and/or tissue, the bone plate assembly can be used to fuse anatomical structures (such as adjoining bones) and/or to heal a fracture in bone.
