Abstract
A staple for stabilizing the attachment of a vertebral screw and a longitudinal member to the spine. The staple has a plate with first and second apertures. All the staple's legs, prongs, or spikes attached to the underside of the staple are located closer to one particular aperture than the other. Preferably, the plate is also “bow-tie” shaped with a groove that separates the wings of the bow-tie. This bow-tie or hour glass shape combined with the groove help the surgeon to more easily conform the plate to the patient's vertebra.
