a screw member positioned between the upper endplate and the lower endplate, the screw member comprising a shank comprising threads that engage at least one of the proximal wedge and the distal wedge such that rotation of the screw member in a first direction about an axis of the shank draws at least one of the proximal wedge and the distal wedge toward each other to move the implant to an expanded configuration, and rotation of the screw member in a second direction about the shank separates at least one of the proximal wedge and the distal wedge from each other to move the implant toward a collapsed configuration; and

Once the user confirms that the expandable intervertebral implant is properly positioned and expanded, the user can rotate the knob 450 to extend the inserter fork 430. Extending the inserter fork 430 causes the bias member 540 to move the protrusions 522 out of the recesses 524 and thereby detach the expandable intervertebral implant 100 from the inserter 400. If needed, the process can be reversed to retrieve an expandable intervertebral implant 100 using the inserter 400.

Referring now to FIGs. 4A, 4B, and 5, examples of using the inserter 400 are described. With an expandable intervertebral implant 100 attached to the inserter 400, the knob 450 engages threads 550 of the inserter fork 430 such that the prongs 520 are retracted within the arm 414. In such a configuration, the legs 542 of the bias member 540 are biased against internal walls of the arm 414. A user can then take the inserter 400 by the handle 420 and position the expandable intervertebral implant between vertebral bodies for the procedure. Once, the expandable intervertebral implant 100 is positioned, a user can rotate the driver 440 which rotates the screw member 118 which expands the expandable intervertebral implant from a collapsed configuration to either a partially expanded configuration or a fully expanded configuration.
