An apparatus for spinal fixation has a longitudinally extending core which provides structural integrity and allows for bone growth along the center column of the spine. The apparatus for spinal fixation further includes upper and lower platform members radially extending from upper and lower ends, respectively, of the core. The platform members each include a plurality of radially extending arms which define substantially triangular openings therebetween. The openings permit bone ingrowth therethrough to the space between the upper and lower platform members which is interrupted only by the core.
