Abstract

Methods and devices for spacing vertebral members using modular intervertebral devices and insertion tools. The devices may include opposing first and second endplates, and an intermediate member configured to fit between and support the endplates. The insertion tool may include an elongated handle and a distracter. A method of inserting the device using the tool may include inserting the endplates positioned on opposing sides of the handle into the intervertebral space and positioning the endplates in the intervertebral space relative to first and second vertebral members. The method may include deploying the distracter and increasing a distance between the endplates. Another step may include inserting the intermediate member into the intervertebral space and between the endplates and supporting the endplates with the intermediate member. The insertion tool may then be removed from the intervertebral space.
