a tip proximate to the second end; and
a hole extending from the first end to the second end.
11. The alignment guide apparatus of claim 1 , wherein the screw has a first end and a second end, the screw 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 portion and a threaded portion; and
a through hole extending from the first end to the second end.
12. A bone plate alignment system, comprising:
a bone plate, comprising:
at least one through hole, wherein at least one of the at least one through holes is a compression slot;
a bone plate alignment guide, comprising:
a body, comprising:
an arm with a first end and a second end;
an attachment portion; and
an alignment portion;
a fixation insert rotatably coupled to the attachment portion, wherein the fixation insert couples with the bone plate; and
a guide wire configured to pass through the alignment portion;
a screw;
at least one first fastener for insertion through at least one of the at least one through holes of the bone plate and into a first portion of bone; and
at least one second fastener for insertion through at least one of the at least one through holes of the bone plate and into a second portion of bone, and
wherein the attachment portion is positioned superior to the alignment portion in a direction extending from a bottom bone contacting surface to a top surface of the bone plate when the fixation insert engages the bone plate.
13. The bone plate alignment system of claim 12 , wherein the screw is configured to engage the guide wire.
14. The bone plate alignment system of claim 12 , further comprising:
a drill configured to be inserted over the guide wire.
