Intervertebral cage

Abstract

The present invention relates to interbody cages. The interbody cage, suitable for interposition between two vertebrae V1, V2, comprises an element 10 having the general shape of a disc defining two opposite faces 11, 12 adapted to come into contact with the two vertebrae respectively; means for locking the element with a single vertebra V1, consisting of a first half-blade 31 and a second half-blade 32, each defined in a plane; means for rotating these two half-blades relative to the element via a rotation shaft 48 with axis of rotation 100; and means for fixing each half-blade on the same side of the rotation shaft 48 opposite each other and such that their planes form an angle other than zero.
