Abstract:
A posterior spinal osteosynthesis device comprising; at least two pairs of hook members and two vertebral rods adapted to be received in a channel defined in a frontal body portion of each hook member, each hook member including a stem extending rearwardly relative to said frontal body portion and in a plane extending generally transversely to longitudinal axes of the two vertebral rods, the stems being oriented to be adapted to bear laterally on transverse processes of a vertebra, a pair of parallel rods which are joined together and bent elastically to form a generally transverse arc extending between each pair of hook members, each pair of parallel rods having ends which engage in bores formed in each hook member, and securing means for securing the hook members to the ends of the parallel rods of the transverse arc so as to create an elastic restoring force by way of the transverse arc and the hook members which are adapted to bear on the transverse processes.
