Abstract
An expandable implant includes a top support assembly defining an upper surface configured to engage a first portion of vertebral bone; a bottom support assembly defining a lower surface configured to engage a second portion of vertebral bone; and a control assembly coupled to the top support assembly and the bottom support assembly and configured to control relative movement between the top support assembly and the bottom support assembly between a collapsed position and an expanded position. In the collapsed position, the upper surface is generally parallel to the lower surface, and in the expanded position, a portion of the upper surface extends at an acute angle relative to a portion of the lower surface.
