Abstract
A bone plate for stabilizing adjacent vertebrae or ends of a bone having a span for extending across the discontinuity. The span has brackets for attaching to the bone. The brackets have countersunk apertures terminating through which bone screws are placed in the bone. An cam bore is located between the countersunk apertures and a cam with lobe surfaces is positioned in the cam bore. Upon rotation of the cam, the lobe surfaces engage an end of the wedge shoes and move them so that the other end of the wedge shoes move into the countersunk apertures and frictionally engage the heads of the bone screws. The wedge shoe is provided with means to lock the cam in position. The wedge shoe is also provided with means to indicate that the shoe has completely engaged the head of the bone screw in the countersunk aperture.
