Abstract
A method and apparatus for the effective delivery of a material, such as cement, to a desired location in a human. In one embodiment of the invention, a bone screw, including a head portion, a cannulated slotted shaft portion and a tip portion, includes an injection site for removably attaching an injection device, such as a syringe. Since the shaft portion is slotted, injected material flows from the cannulated shaft and is able to exit into surrounding tissue through the slot in the shaft.
