  • Publication number: 20150265415
    Abstract: Prosthetic intervertebral discs, systems including such prosthetic intervertebral discs, and methods for using the same are described. The subject prosthetic discs include upper and lower endplates separated by a compressible core member. The subject prosthetic discs exhibit stiffness in the vertical direction, torsional stiffness, bending stiffness in the saggital plane, and bending stiffness in the front plane, where the degree of these features can be controlled independently by adjusting the components, construction, and other features of the discs.

  • Publication number: 20110082552
    Abstract: The described devices are bound spinal implants that may be surgically implanted into the spine to replace damaged or diseased discs using a posterior, lateral, or postero-lateral approach. The discs are prosthetic devices that approach or mimic the physiological motion and reaction of the natural disc.

  • Publication number: 20080183209
    Abstract: Spinal stabilization devices, systems, and methods are described. Foramenal spacers including a rigid member adapted to maintain the integrity of the foramenal space. Facet joint stabilizing members and prosthetic facet joints that augment or replace the native facet joint are also described. Lateral spinal stabilization systems that may be attached to the lateral surfaces of adjacent vertebral bodies are described. Also described are anterior spinal stabilization systems that are to be attached to the anterior surfaces of adjacent vertebral bodies. Several variations of dynamic spinal stabilization devices and systems are described. Each of the foregoing devices, systems, and methods may be used independently, in combination with the other devices, systems, and methods described herein, and/or in combination with prosthetic intervertebral discs.
