A spinal plate system (30) that maintains intervertebral spacing and spinal stability is provided. In an embodiment, a spinal compression plate (30) may include two or more plates (32, 34) coupled together form an adjustable-length plate. Movement of plates (32, 34) in a spinal compression plate (30) may be uni-directional. Compression of a spinal compression plate movement may mimic natural settling of bones in a spine and/or distribute at least a portion of a vertebral load to an implant positioned between two vertebrae. Maintaining at least a portion of the vertebral load on an insert may increase bone growth and increase fusion between an implant and surrounding vertebrae.

L'invention concerne un système de plaque dorsale qui maintient l'espace intervertébral et stabilise la colonne vertébrale. Dans un mode de réalisation de l'invention, une plaque de compression dorsale peut comprendre au moins deux plaques qui sont accouplées l'une à l'autre de manière à former une plaque réglable en longueur. Le mouvement des plaques dans la plaque de compression dorsale peut s'effectuer dans une seule direction. Le mouvement de compression d'une plaque de compression dorsale permet d'imiter le tassement naturel des os de la colonne vertébrale et/ou de répartir entre deux vertèbres au moins une partie de la charge exercée par les vertèbres sur un implant. Le maintien d'au moins une partie de la charge exercée par les vertèbres sur un implant permet d'accroître la croissance osseuse et la fusion entre un implant et les vertèbres situées autour de ce dernier.
