<p>An expandable intervertebral implant (20) including an implant body (22) transitionable between an initial configuration and an expanded configuration, and having first and second axial walls (30,32) spaced apart along a transverse axis (T) with at least one of the walls (30,32) defining a recessed I'egion when the implant body (22) is in the initial configuration. An expansion member (24) co-acts with the axial wall (30, 32) to transition the implant body (22) to the expanded configuration wherein the recessed region is outwardly expanded generally along the transverse axis (T) . In another embodiment, the expansion member (24) includes a first portion (100) that is displaced along an axially extending slot (80) formed in one of the walls (30, 32) , and a second portion (102a, 102b) that is displaced between the walls (30, 32) to transition the implant body (22) to the expanded configuration. In a further embodiment, the first portion (100) of the expansion member (24) defines a passage (110) extending therethrough having an inner transverse dimension sized larger than an outer transverse dimension of the second portion (102a, 102b) .</p> |
