FIGS. 14A and 14B illustrate use of a reinforcement member on a single connector which does not include a compliance member, while FIGS. 15A and 15B illustrate use of a reinforcement member on a single connector which includes a compliance member.
Further details and alternative embodiments of flexion limiting devices, their use, and associated instruments are disclosed in the patent applications previously incorporated herein by reference.
Referring now to FIG. 14, yet another spinous process constraint system 1460 comprises first and second hook-like attachment members 1462 and 1464. The hook members 1462 and 1464 are connected in a C-shaped pattern, as shown in FIG. 14.
The spinous process constraint 1460 of FIG. 14 will have a tendency to deform when placed under an axial load as the spinous processes undergo a flexion causing movement in the direction of arrow 1465. Typically, a region 1466 of the constraint will tend to bow inwardly which causes the superior and inferior hook members 1462 and 1464 to displace laterally, increasing the risk that they will shift from their intended positions on the spinous processes. In order to alleviate this condition, a reinforcement member 1467 can be placed over a portion of the single connector 1463 between the hooks 1462 and 1464. The reinforcement member may be a simple sleeve constructed from a relatively rigid material, such as a metal or rigid polymer, having a central passage which is placed over the single connector. Other reinforcement structures would also be possible. Additionally, the sleeve embodiment shown in FIG. 14B could be modified to be used with constraint embodiments including compliance members as described elsewhere in this application.
Similarly, as shown in FIG. 15, a spinous process constraint system 1570 comprises first and second hook-like attachment members 1572 and 1574 arranged in C-shaped pattern, generally as shown in FIG. 14, and further comprises compliance member 1578 attached to superior and inferior segments of the single connector 1576 (which is preferably non-compliant).
The spinous process constraint 1570 of FIG. 15 can also undergo deformation when subjected to an axial load, as shown in FIG. 15A. A reinforcement assembly 1573 specifically adapted for constraints having compliance members 1578 is illustrated in FIG. 15B. The reinforcement assembly 1573 connects to a superior segment 1575 of the single connector 1576 and includes a slide rod 1571 extending toward an inferior segment 1577 of the single connector 1576. The slide rod 1571 is received in a bearing structure 1579 attached to the interior segment 1577 which allows the rod to translate as the segments 1573 and 1577 move toward and away from each other as the spine undergoes extension and flexion. The reinforcement assembly 1571 helps maintain the proper alignment between the superior and inferior segments 1575 and 1577 to prevent the bowing and deformation illustrated in FIG. 15A.
1. A method for restricting flexion of a spinal segment having a spinal midline, said method comprising:
providing a first attachment element and a second attachment element, wherein the first attachment element is joined to the second attachment element with one connector extending therebetween and wherein the one connector has an elastic stiffness in tension that resists flexion of the spinal segment without resisting extension thereof, wherein the one connector provides the elastic stiffness in tension between the attachment elements in the range from 7.5 N/mm to 50 N/mm;
engaging the first attachment element to a first spinous process;
engaging the second attachment element to a second spinous process or a sacrum;
disposing the one connector beside one side of the spinal midline; and
providing a reinforcement member that limits deformation of the one connector under an axial load, wherein the reinforcement member is coupled to the one connector.
2. The method of claim 1, wherein the elastic stiffness in tension is in the range from 10 N/mm to 25 N/mm.
3. The method of claim 2, wherein the elastic stiffness in tension is in the range from 10 N/mm to 15 N/mm.
4. The method claim 1, wherein the one connector provides an elastic stiffness in compression between the attachment elements below 3 N/mm.
5. The method of claim 4, wherein the elastic stiffness in compression is below 0.5 N/mm.
6. The method of claim 1, further comprising percutaneously introducing the attachment elements and the one connector.
7. The method of claim 6, wherein percutaneously introducing the attachment elements and the connector comprises introducing the attachment elements and the connector from one side of the spinal midline.
8. The method of claim 6, wherein percutaneously introducing the attachment elements and the connector comprises introducing the attachment elements and the connector from a posterior approach.
9. The method of claim 1, wherein the first and second attachment elements comprise hooks for engaging the spinous processes or sacrum.
10. The method of claim 9, wherein engaging the attachment elements to the spinous processes or sacrum comprises introducing the hooks in a retracted configuration and pivoting the hooks relative to the connector to capture the spinous processes or sacrum.
11. The method of claim 10, wherein the first attachment element comprises a superior hook and the second attachment element comprises an inferior hook, and wherein engaging the first attachment element comprises engaging the superior hook to a superior surface of the first spinous process and engaging the second attachment element comprises engaging the inferior hook to an inferior surface of the second spinous process or sacrum.
12. The method of claim 1, wherein providing the reinforcement member comprises providing a reinforcement sleeve disposed over the one connector.
13. The method of claim 1, wherein the one connector comprises a superior segment and an inferior segment, and wherein the one connector further comprises a compliance member attached to the superior and inferior segments of the connector.
14. The method of claim 13, wherein providing the reinforcement member comprises providing a slide assembly adjacent to the compliance member, and wherein the slide assembly aligns the superior and inferior segments of the connector.
