1. A variable lordosis endplate comprising:
a body having a body upper surface;
a driver coupled to the body upper surface;
an upper endplate having an endplate lower surface hingedly coupled to the body upper surface;
a shuttle having a first part coupled to the driver for axial translation and a second part coupled to the upper endplate lower surface for lifting translation, wherein the driver includes a threaded portion coupled to the first part of the shuttle, and rotation of the driver axially translates the shuttle;
wherein the driver is configured to simultaneously translate the shuttle axially and lift the upper endplate angularly away from the body to change a lordosis angle;
wherein the second part of the shuttle includes angled slots coupled to the upper endplate with a shuttle pin, during axial translation of the shuttle on the threaded portion of the driver, the shuttle pin translates up the angled slots to lift the proximal end of the upper endplate away from the body to change the lordosis angle.
