Abstract
The present disclosure generally relates to an intervertebral disc prosthesis for partially or totally replacing an organic intervertebral disc. The disc prosthesis includes an interbody device, a face plate and a pair of locking mechanisms for achieving dual fixation in the cephalad and caudal direction. Methods according to the present disclosure achieve such dual fixation in a single fixation step.
Claims5
A method of using an intervertebral disc prosthesis, comprising:
- providing an intervertebral disc prosthesis, the prosthesis comprising an interbody device, a face plate having one or more fixation mechanisms integrally connected therewith, and one or more additional fixation mechanisms;
- connecting the face plate to the interbody device such that the one or more fixation mechanisms are substantially disposed within a central opening defined in the interbody device;
- inserting the interbody device and face plate into an intervertebral disc space;
- and
- inserting the one or more additional fixation mechanisms through the face plate and interbody device and into a first vertebral endplate;
- whereby inserting the one or more additional fixation mechanisms urges the face plate against the interbody device, thereby causing the one or more fixation mechanisms to rotate into a second vertebral endplate opposing the first vertebral endplate.
