a drill bit for insertion into a drill guide member in the implant template.
3. The bone fusion system of claim 1 , wherein the implant template comprises:
a first distal lobe positioned on a plantar side of a first end of the implant template;
a second distal lobe positioned on a dorsal side of the first end of the implant template;
a proximal lobe positioned on the plantar side of a second end of the implant template; and
a proximal drill guide member positioned on the dorsal side of the second end of the implant template.
4. The bone fusion system of claim 1 , wherein the implant template further comprises:
an alignment opening positioned near a proximal end of the implant template; and
a positioning slot positioned near a distal end of the implant template.
5. The bone fusion system of claim 1 , wherein the implant template further comprising:
a first alignment guide opening positioned near the distal end of the implant template; and
a second alignment guide opening positioned between the first alignment guide opening and a mid-point along a longitudinal axis of the implant template.
6. The bone fusion system of claim 1 , wherein the plate comprises:
an angled lobe positioned on a dorsal side of a proximal end of the plate, wherein the angled lobe is angled relative to a horizontal plane and a top plane of the plate.
7. The bone fusion system of claim 6 , wherein the angled lobe comprises a bone contacting surface, wherein the bone contacting surface is at least one of a curved or semi-circular shape.
8. The bone fusion system of claim 6 , wherein the plate further comprises:
a first distal lobe positioned on a plantar side of a distal end of the plate;
a second distal lobe positioned on the dorsal side of the distal end of the plate; and
a proximal lobe positioned on a plantar side of the proximal end of the plate.
9. The bone fusion system of claim 8 , wherein each of the lobes comprises an opening extending through the plate from an exterior surface to an interior surface.
10. The bone fusion system of claim 9 , wherein the opening in the proximal lobe comprises a compound angle, wherein the compound angle comprises:
a first angle, wherein the first angle is the angle of a central axis of the opening from a horizontal plane; and
a second angle, wherein the second angle is the angle of the central axis of the opening from a dorsal plane.
11. The bone fusion system of claim 8 , wherein the plate further comprises:
an alignment opening positioned near a proximal end of the plate; and
a positioning slot positioned near the distal end of the plate.
12. The bone fusion system of claim 8 , wherein the plate further comprises:
a first alignment guide opening positioned near the distal end of the plate; and
a second alignment guide opening positioned between the first alignment guide opening and a mid-point along a longitudinal axis of the plate.
13. The bone fusion system of claim 1 , wherein the attachment portion comprises a through hole configured to receive the fixation member.
14. The bone fusion system of claim 13 , wherein the alignment portion comprises:
at least one through hole for receiving the guide pin protector.
15. The bone fusion system of claim 1 , wherein the fixation member comprises:
a knob portion; and
a shaft portion extending away from the knob portion.
16. The bone fusion system of claim 15 , wherein the shaft portion comprises:
an engagement region; and
a recessed region positioned adjacent to the engagement region.
17. The bone fusion system of claim 1 , wherein the compression screw has a first end and a second end, the screw further comprising:
a head portion at the first end;
a shaft portion extending away from the head portion to the second end, wherein the shaft portion comprises a smooth region and a threaded region; and
a through hole extending from the first end to the second end.
18. The bone fusion system of claim 1 , wherein the alignment portion is tapered from a first side to a second side.
19. The bone fusion system of claim 9 , wherein the exterior and interior surfaces are non-planar.
