Abstract

An intervertebral implant includes a body portion defining a longitudinal axis. The body portion includes a distal end portion, a proximal end portion, anterior and posterior walls that extend between the distal and proximal end portions, and top and bottom surfaces. At least one of the top and bottom surfaces includes a plurality of substantially concentrically arranged ridges configured and adapted to engage vertebral bodies. In particular, the plurality of substantially concentrically arranged ridges are a plurality of ring-shaped protrusions that define a generally saw-tooth pattern in a radial direction.
