FIG. 2E illustrates a side view of the screw member 118 of the expandable intervertebral implant 100 of FIG. 1A. The screw member 118 may generally include a shank 236, a head 238, and threads 240 on one end of the shank 236. The screw member 118 may include a groove 242. In one embodiment, the screw member 118 can be a jackscrew. The groove 242 may be sized and configured to seat a ring 243 or washer (See FIG. 3A). In certain embodiments, the ring 243 sits within the groove 242 when the expandable intervertebral implant 110 is in a collapsed configuration. The ring 243 may comprise a retaining ring. In a collapsed configuration, the ring 243 may keep the screw member 118 positioned within the proximal wedge 114. Alternatively, or in addition, the ring 243 may serve to prevent the screw member 118 from un-screwing from the distal wedge 116 when the screw member 118 is rotated in a particular direction. The ring 243 can be made of a variety of materials including plastic, rubber, ceramic, metal, or the like.
