摘要：
An intervertebral prosthesis includes: a body； at least three apertures extending from within the body； at least three anchoring elements disposed within the at least three apertures； and a drive mechanism operating to simultaneously push the at least three anchoring elements out through the apertures, where: a first deployment direction of a first of the anchoring elements includes: (i) a first substantial directional component in one of an anterior and posterior direction of the body； and (ii) a second substantial directional component parallel to the longitudinal axis of the body； a second deployment direction of a second of the anchoring elements includes: (i) a first substantial directional component in one of an anterior and posterior direction of the body； and (ii) a second substantial directional component parallel to the longitudinal axis of the body and opposite to the second substantial directional component of the first deployment direction of the first anchoring element； and the drive mechanism operates to move the first anchoring element at least some distance in the first deployment direction and to move the second anchoring element at least some distance in the second deployment direction.
