Abstract
A spine surgery modeling system simulates the spine with various vertebral body or disc conditions and allows a user to make adjustments and examine the three dimensional outcome of such adjustments. The spine surgery modeling system includes a spine model and a drive mechanism. The spine model has vertebral bodies and a disc space defined between adjacent vertebral bodies. The drive mechanism includes a worm gear, a worm, a rigid shaft, and a button. The worm engages the worm gear such that rotation of the worm causes rotation of the worm gear. The rigid shaft extends through a through hole defined in the worm and is configured to rotate the worm. The button is operatively engaged with the worm gear such that rotation of the worm gear causes movement of the button between collapsed and expanded states to change a height of the disc space.
