A prosthetic device for placement in an intervertebral space defined between an upper vertebra and a lower vertebra to provide articulating motion to the upper and lower vertebrae may includes an upper articular portion configured to be at least partially disposed in the intervertebral space and a lower articular portion configured to be at least partially disposed in the intervertebral space. The lower articular portion may be configured to cooperate with the upper articular portion to provide articulating motion to the upper and lower vertebrae. An attachment element may extend in the general direction of the spinal column. The attachment element may be configured to be fastened to at least one of the upper and the lower vertebrae to at least partially secure in place said one of the upper and lower articular portions. A method of implanting also is disclosed.
A prosthetic device for placement in an intervertebral space defined between an upper vertebra and a lower vertebra to provide articulating motion to the upper and lower vertebrae, comprising:
A motion-preserving prosthetic device component for placement in an intervertebral space defined between an upper vertebra and a lower vertebra, comprising an articular portion configured to be at least partially disposed in the intervertebral space, the articular portion being configured to cooperate with a mating articular portion to provide articulating motion to the upper and lower vertebrae, the articular portion including a body and an attachment element,
A motion-preserving prosthetic device component for placement in an intervertebral space defined between an upper vertebra and a lower vertebra, comprising an articular portion configured to be at least partially disposed in the intervertebral space, the articular portion being configured to cooperate with a mating articular portion to provide articulating motion to the upper and lower vertebrae, the articular portion including a body and a flexible attachment element, wherein the body is configured to be fixed relative to one of the upper and lower vertebrae, and the flexible attachment element is configured to attach to the other of the upper and lower vertebrae.
A method of implanting a prosthetic device in an intervertebral space defined between an upper vertebra and a lower vertebra to provide articulating motion to the upper and lower vertebrae, comprising:
