Spine stabilization device and method
View Patent ↗A spine stabilization device is provided including an elongate member coupled to a spinous process. One aspect includes a dynamic stabilizer in a stabilization device.
1. A method for implanting a spine device so as to stabilize vertebrae of a spine, the method comprising the steps of:
accessing the spinous process;
inserting an elongate member comprising a proximal portion and a distal portion into the vicinity of the spinous process at an oblique angle with respect to the median plane of a spine;
fixing the elongate member to the spinous process by fixing the proximal portion to a location on the spinous process of a first vertebra;
fixing a pedicle attachment device to a pedicle of a second vertebra; and
coupling the distal end portion of the elongate member to the pedicle attachment device, thereby limiting relative motion of the first and second vertebrae, wherein the step of fixing the elongate member comprises positioning the elongate member through the spinous process.
2. The method of claim 1 further comprising the step of reinforcing the spinous process.
3. The method of claim 1 wherein the first vertebra is adjacent the second vertebra.
4. The method of claim 1 when the first vertebra is not immediately adjacent the second vertebra.
5. The method of claim 1 wherein the elongate member comprises a stabilizer with limited motion.
6. The method of claim 1 wherein the elongate member comprises a stabilizer with shock absorbing properties.
7. The method for implanting a spine device of claim 1 wherein the step of fixing the elongate member comprises attaching the elongate member to the base of the spinous process.
8. The method of claim 1 wherein the step of accessing the spinous process comprises minimally invasively accessing the spinous process and minimally invasively inserting the elongate member.
9. A method for implanting a spine device so as to stabilize vertebrae of a spine, the method comprising the steps of:
accessing the spinous process;
inserting an elongate member comprising a proximal portion and a distal portion into the vicinity of the spinous process at an oblique angle with respect to the median plane of a spine;
fixing the elongate member to the spinous process by fixing the proximal portion to a location on the spinous process of a first vertebra;
fixing a pedicle attachment device to a pedicle of a second vertebra; and
coupling the distal end portion of the elongate member to the pedicle attachment device, thereby limiting relative motion of the first and second vertebrae, wherein the elongate member comprises a rod comprising a proximal head, wherein the step of fixing the elongate member comprises attaching the rod to the spinous process so that the head engages the spinous process, and wherein the step of attaching the rod to the spinous process comprises positioning the rod through the spinous process.
10. A method for implanting a spine device so as to stabilize vertebrae of a spine, the method comprising the steps of:
accessing the spinous process;
inserting an elongate member comprising a proximal portion and a distal portion into the vicinity of the spinous process at an oblique angle with respect to the median plane of a spine, wherein the elongate member comprises a rod with an adjustable length;
fixing the elongate member to the spinous process by fixing the proximal portion to a location on the spinous process of a first vertebra;
fixing a pedicle attachment device to a pedicle of a second vertebra; and
coupling the distal end portion of the elongate member to the pedicle attachment device, thereby limiting relative motion of the first and second vertebrae.
