A spinal implant includes a bone implant body having a superior end face,
an inferior end face, and an outer sidewall extending between each end
face. There are at least two flat sidewall portions on the outer sidewall
to enhance the gripping of a gripping instrument. In a first embodiment,
the two flat sidewall portions each have a pin insertion hole, the holes
being offset at about a 30 degree angle from each other. In a second
embodiment, concentric cuts are included on the superior and inferior end
faces. In a third embodiment, radial cuts are included on the superior
and inferior end faces. In a fourth embodiment, at least one pin hole on
the flat sidewall portions includes stress relief means. Three methods
are disclosed of forming an implant by (1) cutting concentric cuts, (2)
cutting radial cuts, and (3) cutting both concentric cuts and cutting
radial cuts on the superior and inferior end faces.
