A dynamic implanted spinal orthosis which preserves at least in part the natural physiological mobility of the vertebrae while effecting and maintaining a correction of the relative positions of the vertebrae without osteosynthesis, graft or fusion, comprising anchoring components fixed to the vertebrae and holding means associated with the anchoring components for holding the vertebrae with respect to each other in the corrected position, the holding means comprise an elastic return device for exerting elastic return forces, the orientation and magnitude of which are determined for holding the vertebrae in the corrected position against natural deforming forces for reducing the forces exerted on the vertebrae while preserving their mobility; also a procedure for maintaining a correction of the positions of the vertebrae for treating a deformation of the spine.
An implanted dynamic vertebral orthosis for adjusting the relative positions of spinal vertebrae with respect to a vertical axis comprising anchoring members for securing to the vertebrae and holding means connected to the anchoring members, said holding means including at least one curved holding rod which is flexible and elastic in bending and connected to said anchoring members for anchoring at least two different vertebrae, and coupling means for connecting said holding rod to said anchoring members, wherein said coupling means comprises a first coupling member preventing all relative horizontal translational sliding movement of the vertebrae, while permitting relative longitudinal translational sliding movement along said vertical axis and relative rotational movement about said vertical axis of said holding means having elastic return means capable of exerting elastic return forces having predetermined orientation and magnitude between said anchoring members, for holding the vertebrae in a predetermined corrected position against natural deforming forces for reducing the overall forces exerted on the vertebrae.
A process for effecting and maintaining a correction of the relative positions of spinal vertebrae while preserving at least in part the natural physiological mobility of the vertebrae, and implanting a dynamic spinal orthosis by fixing anchoring members to the vertebrae, and connecting holding means to the anchoring members, and including the steps of
Implanted dynamic vertebral orthosis comprising anchoring members for securing to the vertebrae and holding means associated with the anchoring components, wherein the holding means include at least one curved holding rod which is flexible and elastic in bending connected with components for anchoring at least two different vertebrae, wherein each holding rod is connected to the anchoring components by first coupling means preventing all relative sliding movement in horizontal translation with respect to the vertebrae, wherein each holding rod is connected with the anchoring components for at least one vertebra by second coupling means allowing sliding in relative longitudinal translation along a vertical axis, wherein each holding rod is connected with the anchoring components for at least one vertebra by third coupling means allowing relative rotation about a vertical axis, wherein each holding rod is connected with the anchoring components for at least one vertebra by fourth coupling means allowing relative rotation about an horizontal axis, and wherein the holding means is capable of exerting elastic return forces having orientation and magnitude for holding the vertebrae in the corrected position against the natural deforming forces.
A dynamic, implantable vertebral orthosis for adjusting the relative positions of spinal vertebrae comprising anchoring members securable to the vertebrae and holding means associated with the anchoring members, said holding means including at least one curved holding rod which is flexible and elastic upon bending and connected to said anchoring members for attachment to at least two different vertebrae, and coupling means for connecting said holding rod to said anchoring members, said coupling means preventing all relative horizontal translational sliding movement of the vertebrae, said coupling means further permitting relative longitudinal translational sliding movement along a vertical axis and relative rotational movement of the vertebrae about a vertical axis, said holding means having elastic return means capable of exerting elastic return forces having adjustable orientation and magnitude for maintaining the vertebrae in a corrected position against natural deforming forces, or so as to reduce the overall forces exerted on the vertebrae while preserving the mobility and allowing physiological movements of the vertebrae.
