摘要:
Systems and method in accordance with embodiment of the present invention can includes a distractible implant comprising a distracting insert and a body having a first part and a second part adapted to be positioned between adjacent spinous processes of cervical vertebrae. The distracting insert can be inserted into cavities of the body, thereby urging apart the first part and second part, and distracting the adjacent spinous processes.

A spine stabilization prosthesis which supports the spine while providing for the preservation of spinal motion. The spine stabilization prosthesis incorporates a bone anchor having a deflectable post and a compound spinal rod which provide for load sharing while preserving range of motion and reducing stress exerted upon the bone anchors and spinal anatomy. The bone anchor includes a deflectable post connected by a ball-joint to a bone screw. The compound spinal rod includes a coupling mounted to the deflectable post and connected by a pivoting joint to a rod. The combined motions of the ball-joint and the pivoting joint support a range of motion of adjacent vertebrae which closely approximates the natural range of motion of the spine.
摘要:
A dynamic bone anchor for anchoring a spine stabilization assembly which supports the spine while providing for the preservation of spinal motion. The dynamic bone anchor provides load sharing while preserving range of motion and reducing stress exerted upon the bone anchors and spinal anatomy. The dynamic bone anchor includes a deflectable post connected by a ball-joint to a threaded anchor. Deflection of the deflectable post is controlled by a compliant ring. The force/deflection properties of the dynamic bone anchor may be adapted to the anatomy and functional requirements of the patient. The dynamic bone anchor may be used as a component of a dynamic stabilization system which supports the spine while providing for the preservation of spinal motion.

摘要:
A dynamic spinal rod for connecting levels of a dynamic stabilization system to support the spine while providing for the preservation of spinal motion. Embodiments of the dynamic stabilization system have an anchor system, a deflection system, a vertical rod system and a connection system. The deflection system provides dynamic stabilization and load-sharing. The dynamic spinal rod connects different levels of the construct in a multilevel construct. The dynamic spinal rod cooperates with the deflection system to further reduce stress exerted upon the bone anchors and spinal anatomy.
摘要:
A dynamic spinal stabilization linkage for use in stabilizing of the spine. The linkage connects adjacent vertebrae to provide load-sharing and stabilization while allowing natural kinematics. The linkage comprises three rigid bodies joined in series with 3-degree-of-freedom spherical joint between each body. The joints have range-of-motion constraints which limit undesirable intervertebral motion.
