An anterior cervical plate (10) is adapted to engage at least two vertebrae along the anterior cervical spine. The plate (10) comprises at least one cross connector member (18) connecting two substantially parallel support bars (12 & 14) . The anterior surface (11) of the cross connector member (18) is recessed for providing room for the esophagus. The posterior surface (27) of the cross connector member (18) extends slightly into the center of an intervertebral disc space for securing implanted bone graft material, and of course any other suitable intervertebral implant spacer. The preferred configuration of the cross connector member (18) provides torsional resistance for the bone plate (10) . At least two openings (20) are formed in the plate (10) for receiving a fastener therein for fixing the plate (10) to the anterior cervical spine.
L'invention porte sur une plaque cervicale antérieure (10) conçue pour s'appliquer sur au moins deux vertèbres le long de la colonne cervicale antérieure. Ladite plaque (10) comporte au moins un connecteur en croix (18) reliant entre elles deux barres support (12 & 14) sensiblement parallèles. La surface antérieure (11) du connecteur (18) est en creux pour fournir de la place à l'oesophage. La surface postérieure (27) du connecteur (18) s'étend légèrement dans le centre de l'espace du disque intervertébral pour fixer la greffe osseuse implantée, et bien sûr tout implant espaceur intervertébral adapté. La configuration préférée du connecteur en croix (18) confère une résistance à la torsion à la plaque osseuse (10).
