Expandable intervertebral fusion implant

Abstract

An expandable intervertebral fusion implant including an inferior component, a superior component arranged to telescopingly engage the inferior component, and a port arranged in the inferior or superior component. When a first material is introduced through the port, the inferior and superior components are displaced vertically. Each of the inferior and/or superior components can include telescoping components which allow the inferior and/or superior components to be expanded along the length and/or width of the implant before the inferior and superior components are displaced vertically. The expandable intervertebral fusion implant can be expanded with, and locked in place, hydraulic and/or hardenable material. Alternatively, the expandable intervertebral fusion implant can be expanded using a mechanical implement and then hardenable material can be introduced into the implant to maintain the implant in the expanded position.
