[Solution] An expandable intervertebral spacer system has upper and lower plates forming a cage. The top, bottom, and sides of the cage have openings for receiving bone graft material. At least one angled section extends from the upper or lower plate into the cage. The upper and lower plates are connected to each other by a hinge at the proximal end of the cage. The cage is expanded by inserting a push rod from the proximal end of the cage against the angled section, forcing the upper and lower plates apart at a desired angle. A locking mechanism at the distal end of the cage uses a ratcheting mechanism to secure the plates apart. In this ratcheting mechanism, a torsion spring biases a movable strut against a fixed strut, which cooperates with sawtooth engagement on the movable and fixed struts to secure the upper and lower plates apart.
