1. A fluid delivery and bone screw driver apparatus that attaches to a bone screw, the bone screw having a head with a slotted opening therein and a shaft with a cannula and fenestrations, the apparatus comprising:
an outer sleeve having a first proximal end and a first distal end and comprising,
external threads near the first distal end;a grasping surface near the first proximal end; an inner shaft extending through the outer sleeve, wherein the inner shaft has a second proximal end and a second distal end and comprises,
a coupler at the second proximal end;a counter-torque bar at the second distal end wherein, when engaged with the bone screw head, the counter-torque bar extends radially through the slotted opening in the bone screw head, wherein the counter-torque bar further extends outwardly past the outer sleeve so that it can be manually rotated, and wherein the outer sleeve is independently rotatable around the inner sleeve;a gasket at the distal end; and a removable liner that extends through the proximal end of the inner shaft and out of the distal end of the inner shaft.
