A spinal fixation device includes a body defining a proximal surface, a pair of side surfaces, and a pair of angled surfaces extending distally and inwardly from opposite ends of the proximal surface. The proximal surface includes at least one proximal opening. Each angled surface includes at least one screw opening in communication with the proximal opening to define a passage extending through the body. The body is configured for positioning partially within an intervertebral space such that the angled surfaces are disposed in abutting relation with at least a portion of opposed surfaces of the adjacent vertebrae and such that the proximal surface is disposed exteriorly of the intervertebral space to permit insertion of a screw through the screw opening and into one of the opposed surfaces of the adjacent vertebrae.
