1. An expandable intervertebral implant comprising:
an upper body portion;
a lower body portion opposite the upper body portion;
a wedge member connecting the upper body portion to the lower body portion;
a nose member having a tapered distal end and a proximal end opposite the distal end, the nose member slidably connected to the upper body portion and the lower body portion;
an actuator disposed between the nose member and the wedge member for translation of the wedge member toward the nose member; the actuator at a distal end slidably connected the nose member and at a proximal end threadably connecting to the wedge member;
and
a pin connected to the actuator for positioning the nose member relative to the actuator;
wherein the wedge member extends along a longitudinal axis of the implant and the actuator is disposed laterally offset from the longitudinal axis, and
wherein translation of the wedge member along the longitudinal axis of the implant displaces the upper body portion and the lower body portion away from each other, thereby expanding the implant.
