摘要

The material has two small plates, each with two portions (10, 11). One portion is oriented relative to another for supporting against vertebrate body when the latter portion is inserted between two articular sides of adjacent cervical vertebrae. Each portion has a hole to receive a screw along a direction perpendicular to the portion (11). A connection unit assembles a connection rod to the plates fixed to the vertebrae.
