SELF-STABILISING FUSION CAGE BETWEEN POSTERIOR CERVICAL ARTICULAR PROCESSES

A self-stabilising fusion cage between posterior cervical articular processes, comprising a fusion cage body (2) positioned between upper and lower articular processes when the fusion cage is in place, the front end face of the fusion cage body being fixedly provided with a fixing guide plate (1) forming a certain angle with same, the fixing guide plate (1) and the fusion cage body (2) both being fixed between the upper and lower articular processes by means of a fixing screw (3), the upper and lower end faces of the fusion cage body (2) respectively being provided with a bone graft slot (6), the upper and lower end faces of the fusion cage body (2) also respectively being provided with a plurality of anti-dislocation serrations (5) distributed uniformly around the periphery of the bone graft slot (6), the anti-dislocation serrations (5) and the fixing screw (3) acting jointly to prevent displacement of the fusion cage after fusion due to external force, and the side of the fixing guide plate (1) next to the
