8. The method of claim 1 , wherein the visual image includes a radiograph obtained using a fluoroscopy unit.

9. The method of claim 1 , wherein the preparing the area of tissue is carried out with visual guidance of a fluoroscopy unit.

10. The method of claim 1 , wherein the inserting the screw is carried out with visual guidance of a fluoroscopy unit.

11. The method of claim 1 , wherein the material comprises an osteogenic compound.

12. The method of claim 1 , wherein the material comprises an osteoconductive material.

13. The method of claim 1 , wherein the packing the screw further comprises:

engaging the loading port with the head of the screw;

depressing the plunger into the cannula to dispense the material out of the cannula through the loading port and into the head of the screw through at least one of the one or more openings that are positioned in the head of the screw; and

removing the packing tube and the plunger.

14. The method of claim 1 and further comprising:

a plurality of plunger distance marks disposed on the plunger distance tool, each plunger distance mark is positioned adjacent to and corresponds to only one of the plurality of separate plunger wells, and each plunger distance mark numerically identifies the different size of the screw to be filled with the material.

15. A method, comprising:

obtaining a visual image of a joint and two or more bones connected by the joint;

examining the visual image to confirm a pathology and identify a location in which to insert a screw comprising a shaft having one or more openings;

creating an incision in a tissue adjacent to the joint, the incision configured to provide one or more tools with access to at least one of the two or more bones, the one or more tools including a drill guide comprising a drill guide head;

preparing the location for insertion of the screw, including engaging a bone with the drill guide using a striker tube configured to be placed over the drill guide head, the striker tube comprising a distal edge having a first segment configured to partially encircle a rounded side of the drill guide head and a second segment configured to rest against a proximal side of the drill guide head, the first segment being disposed on a different plane than the second segment;

inserting the screw into the joint and the two or more bones at the location using the one or more tools;

placing a head of a plunger into one of a plurality of separate plunger wells disposed in a plunger distance tool, a position of each plunger well corresponds to a different size of the screw to be filled with a material, a shaft of the plunger is movably positioned inside a cannula of a packing tube of a packing plunger assembly, each plunger well including a wall having a recessed portion for receiving a portion of the shaft when the head is placed in the plunger well;
