Abstract
An opposing taper coaxial spinal implant. The system consists of a centrally located drive screw with opposing lead threads and actuators. The actuators contain pins positioned through angular slots located on sidewalls attached to end plates. The angular slots are opposing to create a wedge effect when the actuator pins translate through them. A carriage contains a drive screw and centrally located pin. The centrally located pin provides axis to contain each end plate, allowing them to pivot and translate relative to the carriage. An adjustment nut is axially retained by the carriage, but allowed to rotate. To expand/contract the end plates, the drive screw and adjustment nut are rotated together, with no relative motion between them. To change the angle of the end plates, the adjustment nut is rotated while keeping the drive screw rotation fixed.
