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. An intervertebral disc prosthesis, comprising:
an interbody device; a face plate adapted to engage the interbody device; a fixation mechanism, the fixation mechanism being connected to the face plate in such a way that rotation of the face plate causes rotation of the fixation mechanism, wherein the fixation mechansim comprises one or more tusk intregrally connected to the face plate; and an additional fixation mechanism, the additional fixation mechanism adapted to engage the face plate to thereby cause rotation of the face plate.
