Abstract
Technologies are generally provided for a spinal fusion device to achieve interbody fusion and maintain intervertebral spacing. The spinal fusion device includes at least two wedge-shaped intervertebral implants (IVIs) configured to be inserted between adjacent vertebrae, such that a thin end of each IVI is positioned toward a midline of the vertebrae, and a thick end of each IVI is positioned substantially flush with outer surfaces of the vertebrae. A lower surface of a superior vertebral body and an upper surface of an adjacent inferior vertebral body are resected to accommodate the IVIs, and a portion of an intervertebral disc (IVD) is also removed to facilitate insertion of the IVIs. The IVIs are inserted in substantially opposite positions to each other between the vertebrae, and an interconnecting member is inserted to connect the IVIs. The interconnecting member passes through residual IVD to stabilize the IVIs in position between the vertebrae.
