<p>An implant assembly (10) is provided for surgical implantation into an intervertebral space (S) such as for stabilization of vertebrae (V) adjacent the intervertebral space (S) during a spinal fusion procedure. The implant assembly (10) includes a primary segment (20) separate from a secondary segment (60). These segments (20, 60) are elongate and of sufficiently small cross-section that they can be implanted posteriorly in a minimally invasive manner. The primary segment (20) preferably includes a tunnel (30) and the secondary segment (60) preferably includes a neck (70) with the tunnel (30) and neck (70) sized complemental so that the segments (20, 60) stabilize each other where they intersect with the neck (70) within the tunnel (30). The entire implant assembly (10) is thus provided which both widens and supports the intervertebral space (S) and is sufficiently rigid to provide adequate support for the intervertebral space (S) as the vertebrae (V) are fusing together.</p> |
