Abstract

Systems and methods for treating musculoskeletal disorders of the spinopelvic anatomy including treating spinal deformities by spinopelvic fixation including fusion of the sacroiliac joint at the base of long spinal fusion construct cases. The system may include implants designed to be used as an adjunct to long spinal fusions to further the immobilization and stabilization of the sacroiliac joint. The implants may be designed to augment an S2AI screw and an S1 screw in order to improve durability of the foundation of the spinal construct. The implants may have a triangular cross section.

First claim

The invention claimed is:

1. A method for stabilizing a first bone and a second bone of a patient, the method comprising:
implanting a first implant into the first bone, the first implant comprising a longitudinally extending first body portion that is at least partially received in the first bone upon implantation and a first coupling portion proximal to the first body portion and configured to couple to a spanning member of a spinal support system;
implanting a second implant into the second bone, the second implant comprising a longitudinally extending second body portion that is at least partially received in the second bone upon implantation, the second body portion of the second implant having a rectilinear cross-section transverse to a longitudinal axis of the second body portion, wherein the second body portion linearly extends along the longitudinal axis;
securing the spanning member to the first coupling portion; and
stabilizing the first and second bones by forming a construct comprising the first and second implants, and the spanning member of the spinal support system.

2. The method of claim 1 , wherein the first bone comprises the sacrum.

3. The method of claim 2 , wherein the second bone comprises the ilium, and wherein the second body portion is at least partially received in the first bone upon implantation of the second implant into the second bone.

4. The method of claim 1 , wherein the spanning member comprises a plate.

5. The method of claim 1 , wherein the second implant comprises first and second planar members coupled to each other, the first and second planar members defining the second body portion.

6. The method of claim 5 , wherein the first and second planar members are coupled together at right angles.

7. The method of claim 1 , wherein the second implant is implanted non-transversely in the sacroiliac joint.

8. The method of claim 1 , wherein the first body portion of the first implant is threaded.

9. The method of claim 8 , wherein the first implant is an S2AI screw.

10. The method of claim 1 , wherein the second body portion of the second implant is non-threaded.

11. The method of claim 1 , wherein the second body portion of the second implant comprises a plurality of struts that define a plurality of openings extending therein.

12. The method of claim 1 , wherein the second body portion of the second implant comprises a hollow core and a plurality of side openings extending into the hollow core.

13. The method of claim 12 , wherein the plurality of side openings comprise rectilinear perimeters.

14. The method of claim 1 , wherein the spanning member is a first spanning member, and the method further comprises operably coupling the first spanning member to a second spanning member that is coupled to a third implant implanted into a third bone.

15. The method of claim 14 , wherein the third bone is a vertebra.

16. A method for stabilizing a vertebra and a pelvic region comprising a sacrum, an ilium, and a sacroiliac joint of a patient, the method comprising:
implanting a first implant into the vertebra, the first implant comprising a first coupling element configured to couple to a rod;
implanting a second implant into the sacroiliac joint such that a first portion of the second implant is positioned in the sacrum, a second portion of the second implant is positioned in the ilium, and a third portion of the second implant is positioned within the sacroiliac joint, the second implant comprising a distal end, a proximal end, a longitudinal axis extending between the distal and proximal ends, and a second implant body extending a length between the distal and proximal ends and having a rectilinear cross-section transverse to the longitudinal axis;
securing the rod to the first coupling element; and
stabilizing the vertebra and the pelvic region by forming a construct comprising the first and second implants and the rod.

17. The method of claim 16 , wherein the second implant further comprises a first planar member extending the length of the second implant body, and a second planar member extending the length of the second implant body, the first and second planar members coupled to each other.

18. The method of claim 17 , wherein the first and second planar members are coupled to each other at right angles.

19. The method of claim 16 , wherein the rectilinear cross-section comprises a cross-shaped cross-section.

20. The method of claim 16 , wherein the second implant is implanted non-transversely into the sacroiliac joint.

21. The method of claim 16 , wherein the longitudinal axis of the second implant body is linear.

22. The method of claim 16 , wherein the second implant is non-threaded.

23. The method of claim 16 , further comprising implanting a third implant into the pelvic region, and operably coupling the third implant to the rod.

24. The method of claim 23 , wherein the third implant comprises a threaded implant.

25. The method of claim 23 , wherein the third implant is implanted into the sacrum.

26. The method of claim 16 , wherein the rectilinear cross-section comprises a triangular cross-section.

27. The method of claim 16 , wherein a first side extends along the length and defines the first portion of the second implant, and a second side opposite the first side extends along the length and defines the second portion.

28. The method of claim 16 , wherein the second implant body of the second implant comprises a plurality of struts that define a plurality of openings extending therein.

29. The method of claim 16 , wherein the second implant body of the second implant comprises a hollow core and a plurality of side openings extending into the hollow core.

30. The method of claim 29 , wherein the plurality of side openings comprise rectilinear perimeters.

31. A method for stabilizing a vertebra and a pelvic region comprising a sacrum, an ilium, and a sacroiliac joint of a patient, the method comprising:
implanting a first implant into the sacroiliac joint such that a first portion of the first implant is positioned in the sacrum, a second portion of the first implant is positioned in the ilium, and a third portion of the first implant is positioned within the sacroiliac joint, the first implant comprising a distal end, a proximal end, a longitudinal axis extending between the distal and proximal ends, and an implant body extending a length between the distal and proximal ends and having a rectilinear cross-section transverse to the longitudinal axis wherein the implant body comprises a plurality of struts that define a plurality of openings extending therein,
wherein the first implant is part of a spinal support system including a second implant positioned in the vertebra, a third implant positioned in the sacrum, and a rod coupled to the second and third implants; and
stabilizing the vertebra and the pelvic region by forming a construct comprising the first implant, the second implant, the third implant, and the rod.

32. A method for stabilizing a vertebra and a pelvic region comprising a sacrum, an ilium, and a sacroiliac joint of a patient, the method comprising:
implanting a first implant into the sacroiliac joint such that a first portion of the first implant is positioned in the sacrum, a second portion of the first implant is po
