INTERVERTEBRAL DISC PROSTHESIS AND METHOD

摘要

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.

主权项

1. 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.
