CA 2586352

A frustum shaped body has an aperture in a top surface and a pair of first and second opposed apertures in a side surface, first and second horizontal internal channels connect both the first and second opposed apertures. A vertical channel from the top aperture connects with the first and second channels. After the body is inserted into a hole in a facet joint, compatible synthetic or biologic material is inserted into the vertical channel until the material exits from the first and second apertures in the side surface. At least one pair of flanges on a portion of an exterior side surface of the body acts as a detent to hold the body in place within the facet joint hole.

L'invention concerne un corps conique à ouverture, sur surface supérieure, et paire de première et seconde ouvertures opposées, sur surface latérale, sachant que des premier et second canaux horizontaux internes relient les ouvertures opposées en question. Un canal vertical depuis l'ouverture supérieure relie les deux canaux. Une fois le corps inséré dans un trou de facette articulaire, on insère un matériau synthétique ou biologique compatible dans le canal vertical jusqu'à sa sortie par les deux ouvertures opposées. Au moins une paire de brides sur une partie de surface latérale externe du corps tient lieu de cran de retenue du corps, en place dans le trou de facette articulaire.
