There is disclosed a system and method for dynamic stabilization which provides for distraction of the inter-vertebral space while still allowing a patient a substantial range of motion. In one embodiment, an inter-vertebral dynamic brace is used to maintain proper distraction. The dynamic brace is designed to allow the vertebrae to which it is attached to move through their natural arc, maintaining the correct instantaneous center of rotation. An adjustable tensioning device is used to maintain the proper distraction and compression forces to restore and maintain proper kinematics, while allowing the dynamic brace to move through an arc centered with respect to the center of rotation of the portion of the spine between the vertebrae. In one embodiment, a method is provided for adjusting the dynamic brace both with respect to the center of rotation of the vertebrae in both the flexion/extension axis and in the superior/inferior axis.

System and method for dynamic skeletal stabilization

An assembly for use in spinal stabilization procedures having first and second bone anchor assemblies. Embodiments of the first bone anchor assembly may include an anchor, a poly-axial head, including a cavity, mated with the anchor such that the anchor is movable relative to the poly-axial head. Embodiments of the second bone anchor assembly may include an anchor, a poly-axial head mated with the second anchor such that the anchor is movable relative to the poly-axial head, a slide ring rotatably mated in the second poly-axial head, and a connector slideably mated in the slide ring along a distal end, and having a proximal end having an enlarged portion. The connector may be movable from a first position axially inline with the second bone anchor to a second position wherein the enlarged portion of the connector rests in the cavity of the first poly-axial head.

Implant assembly and method for use in an internal structure stabilization system

There is shown a system and method for reducing the difficulty in percutaneous placement of a spine stabilization brace. A medical implant system has a first bone anchor having a longitudinal axis, a second bone anchor and a brace. The brace couples the first bone anchor to the second bone anchor. A the distal end of the brace may be pivotally coupled to the first bone anchor and also adapted to slide in a generally transverse direction in relation to the longitudinal axis of the first bone anchor.
