1. An expandable prosthetic implant device for engagement between vertebrae, comprising:
a first body having a circumferential threading and configured to engage a first vertebral body;
a second body slidably coupled to the first body and configured to engage a second vertebral body, wherein the first and second bodies are slidable relative to each other along a longitudinal axis;
a gear positioned coaxially to the first body and second body, and axially fixed to the second body and rotatable with respect to the second body, wherein the gear threadedly engages the circumferential threading of the first body, the gear configured with a plurality of notches;
a lock having a self-locking biased switch movable between a locked position and an unlocked position, the switch attached to the second body and biased to the locked position, and wherein in the locked position the switch engages with one of a plurality of notches to block movement of the gear, and in the unlocked position the switch is disengaged from one of the plurality of notches and allows movement of the gear which allows relative sliding movement between the first body and the second body.
