Expanding orthopedic implant

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 connecting to the upper body portion and the lower body portion;
• and
• an actuator disposed along a longitudinal axis between a tip of the nose member and a back surface of the wedge member;
• the actuator at a distal end connecting to the nose member and at a proximal end connecting to the wedge member,
• 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,
• wherein the wedge member comprises an anterior wedge and a posterior wedge,
• wherein, on a posterior side of the implant, plural dovetail grooves in the nose member respectively hold and slidably connect the upper body portion and the lower body portion to the nose member
• wherein the posterior wedge has a) an upper half with a superior dovetail of the plural dovetail grooves disposed inside a bone graft window and b) a lower half with an inferior dovetail groove of the plural dovetail grooves disposed outside the bone graft window.
