ABSTRACT:
A cannulated screw which maintains compression at the interface between two or more materials in a medical or other setting to effectively secure bone to bone while minimizing separation between the bones and the securement interface. The cannulated screw has a flattened tip, which enables the cannulated screw to more readily bore or self-tap into bone or other material. The flattened tip of the cannulated screw comprises a plurality of cutting teeth which facilitate boring of the flattened tip of the cannulated screw into the material into which the screw is being inserted. In one embodiment, three progressive cutting teeth are provided on the flattened tip of the cannulated screw.
