Title
(EN) CERVICAL SPINE STABILIZATION SYSTEM
(FR) SYSTEME DE STABILISATION DE LA COLONNE CERVICALE
Abstract
(EN)
A method and device for stabilizing cervical vertebrae includes a plate (36) with at least two slots (34). The device also includes at least two screws (14) including a lower threaded bone-engaging shaft (40), a shoulder (44) which will not pass through the plate slots (34), and an upper threaded shaft (42). The screws are positioned and the plate rests on the top of the screw shoulders. Locking, low profile caps (52) secure the plate to the screws.

Procédé et dispositif de stabilisation des vertèbres cervicales, faisant appel à une plaque (36) dotée d'au moins deux fentes (34). Ce dispositif comprend également au moins deux vis (14) présentant une tige filetée inférieure (40) se vissant dans l'os, un épaulement (44) qui ne passe pas à travers les fentes (34) de la plaque, ainsi qu'une tige filetée supérieure (42). Lesdites vis sont mises en position et la plaque vient en appui sur le sommet des épaulements des vis. Des chapeaux de blocage plats (52) fixent la plaque aux vis.
