Abstract
A surgical screw for fixation into bone or soft tissue. The surgical screw includes a cannulated body having a proximal end and a distal end. The distal end of the cannulated body has a tapered tip and a plurality of threads extend around the exterior of the cannulated body. An introducer extends distally from the tapered tip and has a diameter (which can be variable or constant) which is less than a diameter of the tapered tip. The surgical screw is cannulated such that a channel extends through the body from the proximal end to (and sometimes through) the distal end.
