U-shaped intervertebral implant for implanting between cervical vertebrae, has lower lateral branch including transverse rib coming into contact with upper lateral branch to limit connection of free ends of branches

摘要

The implant (1) has a lower lateral branch (2) and an upper lateral branch (3) intended to come into contact with endplates of two vertebrae to be treated, and a curved intermediate branch (4) that is elastically deformable to allow mobility of the lateral branches relative to each other. The lower lateral branch includes a transverse rib (5) projecting toward the upper branch, where the rib comes into contact with the upper branch so as to limit connection of free ends of the lateral branches when forces are exerted on the lateral branches in direction of connection of the free ends. An independent claim is also included for an assembly of an intervertebral implant and a screw.
