Abstract
An intervertebral disc augmentation implant for implantation between a pair of vertebral bodies comprises a core member having a first height dimension along an axis defined by the pair of vertebral bodies and a cavity running perpendicular to the axis, a first post and a second post each having a bottom portion with a plurality of teeth, and a plug having a tapered portion with engaging mechanisms that are configured to mate with the bottom portions of the first and second post. The first and second posts are disposed substantially in the center of the core member along the axis. The bottom portions of the first and second post extend into the cavity at opposite sides of the cavity. The plug is inserted and advanced in the cavity between the bottom portions of the first and second post, thereby expanding the core member from the first height dimension to a second height dimension.
