Abstract
An intervertebral prosthesis includes a body having first and second spaced apart major surfaces defining a longitudinal axis; a first aperture opening at one of the first and second major surfaces; a first anchoring element including a shaft having proximal and distal ends; a translator element coupled to the proximal end of the first anchoring element and having an engagement element that is releasibly engageable with a distal end of an external shaft element that enters the body through an aperture. The shaft element applies forces to the translator to: (i) move along a longitudinal axis within the body, (ii) translate the proximal end of the first anchoring element parallel to the longitudinal axis, and (iii) push the first anchoring element out through the first aperture.
