Abstract:
The described devices are prosthetic, spinal disc replacement, implants having cores that are insertable after the end plates have been introduced into the intervertebral space. The discs may be surgically implanted into the spine to replace damaged or diseased discs using a posterior approach. The discs are prosthetic devices that approach or mimic the physiological motion and reaction of the natural disc.
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 approach. The discs are prosthetic devices that approach or mimic the physiological motion and reaction of the natural disc.
Abstract:
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 prosthetic discs described herein include one-piece, two-piece, three-piece, and four-piece structures. 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 of the discs. The interface mechanism between the endplates and the core members of several embodiments of the described prosthetic discs enables a very easy surgical operation for implantation.
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.

Abstract:
This description deals with a medical device, specifically a prosthetic intervertebral disc having a compressible core that is mechanically interactive with the prosthetic disc's end plates thereby providing excellent torque or twisting transmission between the end plates.
