Abstract:
1. A method of performing spinal surgery, comprising: providing an expandable device, including: inserting the expandable device into an intervertebral space; moving at least one of the first and second support members relative to the other to expand the expandable device from a collapsed position to an expanded position such that the first and second support members engage opposing vertebral bodies; and transitioning the lock mechanism from an unlocked condition, wherein the at least one lock ring plate is oriented in perpendicular orientation relative to the column to permit slidable movement of the column through the at least one lock ring plate, to a locked condition, wherein the at least one lock ring plate is oriented at an oblique angle relative to the column to inhibit slidable movement of the column through the at least one lock ring plate to retain the first and second supporting members in the expanded position.
