Total disc implant
A total disc implant (TDI) is provided for total replacement of a spinal disc or discs in a human patient or other mammal, wherein the TDI is designed to maintain a substantially full range of natural motion (ROM) following implantation. The TDI generally comprises, in one preferred form, upper and lower end plates for affixation to adjacent vertebral bodies, with an intervening insert disposed therebetween. The end plates each include elongated part-cylindrical surfaces oriented generally perpendicular to each other, with one of said surfaces extending in an anterior-posterior direction and the other extending in a medial-lateral direction. The intervening insert defines concave upper and lower part-cylindrical seats oriented for respectively engaging these part-cylindrical surfaces, wherein these part-cylindrical seats are defined by offset radii to include a somewhat flattened central base region merging smoothly with upwardly curving radiused sides.

Intervertebral disc implant
An intervertebral disc implant having a body with a greater height than width comprised of a resilient material and an elongate cavity for receiving a key to maintain the spacing between the vertebrae adjacent an intervertebral disc when implanted into the space from which a portion of the disc is removed. To distribute and cushion against compression loads, and to mimic the normal kinematics of the intact, healthy intervertebral disc, the key is removed after the body is implanted into the disc space and a frame that both provides resistance to compression and tension loads and translates the axis of rotation of the spinal column anteriorally and posteriorally as the patient bends and rotates is inserted into the cavity in the implant body. The frame does not extend all the way into the cavity in the body and the portion of the cavity into which the frame does not extend is filled with a hydrogel.

The present disclosure relates to the field of spine disc implants. Exemplary embodiments of the disclosed spinal disc implants advantageously and ultimately provide fusion with the body of the vertebra and stabilization of the spine in an anatomically correct position, e.g., in cervical, thoracic and / or lumbar regions. More particularly, the present disclosure is directed to a disc implant that addresses and overcomes the shortcomings of the prior implants by providing first and second inter-vertebral elements that are movably coupled relative to each other and are adapted to permit bone in-growth over time. Thus, the disclosed spinal disc implants permit relative movement between the first and second inter-vertebral elements upon implantation and after the patient is mobilized—thereby permitting the implant to assume a desired position based on the specific and unique spinal balance of the patient in an initial post-implantation period—but then the first and second inter-vertebral elements become fixed relative to each other (i.e., fused). The present disclosure also provides advantageous instrumentation and associated methods for positioning a spine disc implant in a desired anatomical location.
