<p>The present invention concerns a modular arthrodesis device, used to enable fusing of two contiguous vertebrae by development of bony tissues with replacement of fibrocartilaginous discs ensuring the bonding between the vertebrae of the vertebral column or the end of the latter, and including interchangeable types of fixation means. Intervertebral arthrodesis device designed to be inserted in an intervertebral space (E) separating the opposi te plates (V0) of two adjacent vertebrae (V), characterised in that it comprise s at least one structure called intervertebral cage (1) presenting the shape o f a ring that mayor may not be open, in which at least one part, along the axi s of the spine, has a lower height that the rest of this same cage and forms a small bar (12) crossed by at least one drilling (121, 122) of the axis approximately perpendicular to the plate (V0) of at least one of the adjacen t vertebrae (V).</p> |
