A posterior fixation system includes a saddle member, and anchoring member, an occipital plate, an occipital rod, and a cross-link connector. The anchoring member anchors the saddle member to bone. The saddle member includes a pair of upright portions that define a channel. The channel is adapted to receive an orthopedic rod, and the saddle member can include a hole to receive the anchoring member. The saddle member and the anchoring member can be coupled so as to allow multi-axial movement of the members. The anchoring member in one embodiment is a screw coupled to the hole of the saddle, and in another embodiment, the anchoring member is a hook. The offset member may be coupled to the saddle member to allow for offset connection of rods. Connection of individual rods can be accomplished by connecting the rods with the cross-link connector. The cross-link connector has an integrally formed cylindrical member that couples a pair of coupling portions together. The cylindrical member can be bent along multiple axes. The occipital plate secures the rods to the occipital bone of the skull. The occipital plate has a cross-shaped plate with a plurality of apertures defined in the plate and at least one saddle member coupled to the plate. Alternatively, the occipital rod can be secured to the occipital bone.

L'invention concerne un système de fixation postérieur comprenant une semelle, un élément d'ancrage, une plaque occipitale, une tige occipitale et un raccord en croix. L'élément d'ancrage permet d'ancrer la semelle à l'os. La semelle comporte deux parties verticales qui définissent un canal, lequel est conçu pour recevoir une tige orthopédique, et la semelle peut comporter un trou destiné à recevoir l'élément d'ancrage. La semelle et l'élément d'ancrage peuvent être couplés de façon à faciliter le mouvement multi-axial des membres. Dans un mode de réalisation, l'élément d'ancrage est une vis couplée au trou de la semelle et, dans un autre mode de réalisation, l'élément d'ancrage est un crochet. L'élément coudé peut être couplé à la semelle afin de permettre le raccordement coudé des tiges. On peut réaliser le raccordement des tige individuelles en raccordant celles-ci à l'aide d'un raccord en croix, lequel est pourvu d'un élément cylindrique solidaire qui relie ensemble deux parties de couplage. L'élément cylindrique peut être plié suivant plusieurs axes. La plaque occipitale, qui permet de fixer les tiges à l'occipital du crâne, est pourvue d'une plaque en croix à plusieurs ouvertures définies dans la plaque et au moins une selle couplée à cette dernière. La tige occipitale peut également être fixée à l'occipital.
