Osteosynthesis device for correction of spinal deformation

Abstract

Abstract This device comprises two rods (1, 2), namely an anterior rod and a posterior rod, plates (4) for fixing the anterior rod (1) to the end vertebral bodies for example (D12 and L3) having a curved surface corresponding to the anterolateral anatomy of the vertebral bodies, these plates (4) being equipped with screws (14) for locking the rod (1) and with cancellous bone screws (5); screws (3) ensure the osseous anchoring of the posterior rod (2), and bars (6) for transverse connection of the rods (1 and 2) constitute, together with the latter, a rigid frame assembly; the anterior rod (1) strengthens the stability and the rigidity of the assembly and is advantageously embedded in a cut (30) formed in the vertebral bodies and then covered with periosteum. <IMAGE>
