Adjustable interbody fusion device and method of use

An interbody fusion device system, comprising:

• an interbody fusion device, comprising:
• a base member including a pivot cylinder;
• a top member including a hinge channel, wherein the pivot cylinder is configured to engage the hinge channel;
• and
• an expansion mechanism for moving the top member relative to the base member;
• and
• an insertion tool, comprising:
• a handle;
• an insertion end;
• at least one tube extending away from the handle and connecting the handle and the insertion end;
• a first knob configured to couple to the handle;
• and
• an actuation bar moveable between a first position and a second position to enable the first knob to engage an adjustment mechanism in the first position and a securement mechanism in the second position.

A method for assembling an interbody fusion device, comprising:

• obtaining a bottom member, an expansion mechanism, and a top member, wherein the bottom member includes a pivot cylinder on a superior surface extending along a length of a first end, and wherein the top member includes a hinge channel positioned on an undersurface along a length of a first end;
• inserting the expansion mechanism into the bottom member;
• securing a first portion of the expansion mechanism in the bottom member;
• coupling the top member to the bottom member including inserting the pivot cylinder into the hinge channel to enable the top member to pivot relative to the bottom member around an outer diameter of the pivot cylinder;
• and
• aligning the top member with the bottom member and a second portion of the expansion mechanism.
