Abstract
An osteosynthesis spinal device comprises two rods (1, 2), anterior and posterior rods, respectively. Plates (4) for fixation of the anterior rod (1) to the extreme vertebral bodies, for example T12 and L3, have an arched surface corresponding to the anterolateral anatomy of the vertebral bodies. The plates (4) are equipped with screws (14) for locking the rod (1) and screws (5) of the cancellous bone type. Screws (3) ensure the osseous anchoring of the posterior rod (2) and bars (6) for transverse connection of the rods (1 and 2) constitute with the rods, a rigid frame assembly. The anterior rod (1) reinforces the stability and the rigidity of the assembly and is advantageously embedded in a furrow (30) made in the vertebral bodies which is subsequently covered with the periostrum.
