Abstract

Implants for positioning between vertebral members. The implant may include a superior surface to contact against a first vertebral member, and an inferior surface to contact against a second vertebral member. The implant may include a central web that extends between first and second flanges. The flanges may be shaped to form gaps that extend the height of the implant. Spaces in communication with the gaps may be formed in an interior of the implant to hold bone growth material.
