A bone fixation device for fixing a first bone to a second bone includes a self tapping screw having an aperture extending along a longitudinal axis of the screw, and a driver having an aperture extending from a proximal end to a distal end along a longitudinal axis of the driver, the distal end being configured to engage the screw such that the aperture of the driver and the aperture of the screw are coaxially aligned, thereby defining a lumen. A guide rod having a tapered tip for piercing bone tissue is shaped and dimensioned to extend through the lumen and configured to fasten to the driver. A blunt-ended rod advances a bioactive agent through the lumen, the blunt-ended rod being dimensioned to extend through the lumen to decrease the injury to vital structures as the screw is advanced into the second bone.
