HYBRID DYNAMIC STABILIZATION

摘要

A spine stabilization for the prophylactic treatment of adjacent level disease. A first vertebral level may be fused by advancing a pedicle screw in the first and second vertebrae and coupling the bone screws to a rigid portion of a rod. A conformable ligature may be passed around a non-pedicle portion of a third vertebra and coupled to a dynamic portion of the rod using a blocking body. The dynamic properties of the dynamic portion of the rod allow movement of the third vertebra relative to the first and second vertebrae to slow down or prevent Adjacent Level Disease in the third vertebra.
