1. An expandable intervertebral spacer, the spacer comprising:
a frame;
a connector having an upper surface and a lower surface;
a first endplate having an upper surface and at least one angled surface engageable with the frame;
a second endplate having a lower surface and at least one angled surface engageable with the frame;
an actuating screw contacting the connector and the frame, rotation of the actuating screw results in the first endplate and the second endplate moving away from each other from a first position to a second position; and
a carriage having a threaded bore configured to receive the actuating screw, wherein the carriage is disposed between the first endplate and the second endplate,
wherein the first endplate and the second endplate each include a recess, at least a portion of the connector is received in the recess of the first endplate and at least another portion of the connector is received in the recess of the second endplate,
wherein the spacer has a curved longitudinal axis when viewed from a position normal to the upper surface of the first endplate, and
wherein the carriage is curved along the curved longitudinal axis of the spacer.
