Abstract: front page image
(EN)Cephalad and caudal vertebral facet joint prostheses and methods of use are provided. The cephalad prostheses are adapted and configured to be attached to a lamina portion of a vertebra without blocking a pedicle portion of the cephalad vertebra. In one embodiment, the facet prosthesis (200) comprises a cylindrical body (205) having an expanded section (250) at a proximal end and a collar (220) securing against the expanded section. A distal collar (225) is secured about the body more proximally. A bearin ball (230) having an opening is fitted and secured over the distal end (215) of the body. In another embodiment, the facet prosthesis (200a) comprises a cylindrical hollow body (205a) having a longitudinally extending bore (207a) and an outer ridge (217a) to engage with a proximal collar (220a).A threaded shaft extends through and is screwed into the bore. The shaft has an enlarged distal plug (265a) to deform the distal end of the hollow body when advanced proximally. A bearing (235) a having an aperture (233) is positioned over the distal end (215a) and locked into place by this deformation.
(FR)Il est fourni des prothèses d'articulations de facettes de vertèbres caudales et crâniales et des procédés d'utilisation. Les prothèses crâniales sont adaptées et configurées pour être attachées à une partie lame d'une vertèbre sans bloquer une partie pédicule de la vertèbre crâniale.
