    Abstract: A method for inserting an intervertebral disc prosthesis into a space between two vertebrae involves inserting the prosthesis partway into the space under constraint to prevent endplates of the prosthesis from articulating, releasing the prosthesis from constraint, and inserting the unconstrained prosthesis farther into the space. In some embodiments, the method involves grasping the prosthesis with a grasping device to insert the prosthesis partway under constraint, loosing the grasping device to release the prosthesis from constraint, and pushing the prosthesis farther into the disc space using the grasping device and/or one or more separate pusher devices. A set includes a grasping device, at least one separate pushing device, and optionally a vertebral spreading device and/or a vertebral midline indicator device.

    Abstract: An interbody spinal fusion cage for posterior interbody fusion procedures includes a superior member and an inferior member connected to each other via a joint. The joint allows the interbody spinal fusion cage to achieve lordosis even if implanted non-orthogonal to the sagittal plane. For example, the joint can be a hinge oriented non-normal to a longitudinal axis of the interbody spinal fusion cage, a polyaxial ball joint, and/or a universal joint. Complementary locking mechanisms, such as locking teeth or a ratchet-and-pawl arrangement, can be provided near the posterior ends of the superior and inferior members in order to prohibit the posterior ends of the superior and inferior members from separating from each other in situ. Bone holes can be provided in the superior and inferior members.
