Abstract: A prosthetic device for posterior placement in an intervertebral space defined between an upper vertebrae and a lower vertebrae may include an upper articular portion configured to be at least partially disposed in the intervertebral space and a lower articular portion configured to be at least partially disposed in the intervertebral space below the upper articular portion, the upper and lower articular portions being configured to provide articulating motion to the upper and lower vertebrae. The upper and lower articular portions each may include a posterior section configured to be disposed in a location posterior of the intervertebral space. The posterior section of one of the upper and lower articular portions may include a post, and the posterior section of the other of the upper and lower articular portions may include a receiving portion configured to interact with the post during articulation.

Abstract: An expandable intervertebral implant including an implant body transitionable between an initial configuration and an expanded configuration, and having first and second axial walls spaced apart along a transverse axis with at least one of the walls defining a recessed region when the implant body is in the initial configuration. An expansion member co-acts with the axial wall to transition the implant body to the expanded configuration wherein the recessed region is outwardly expanded generally along the transverse axis. In another embodiment, the expansion member includes a first portion that is displaced along an axially extending slot formed in one of the walls, and a second portion that is displaced between the walls to transition the implant body to the expanded configuration. In a further embodiment, the first portion of the expansion member defines a passage extending therethrough having an inner transverse dimension sized larger than an outer transverse dimension of the second portion.
