Abstract

A device, method, and system for treatment or fixation of a fractured, damaged, or deteriorating bone or bones in a mid-foot region. The device comprising an implant with both proximal and distal fastener holes, along with fastener slots in a central elongated body, for securing the implant to the appropriate osseous cortical structures of the foot. The method for treatment or fixation of fractured, damaged, or deteriorating bones in the medial column of the foot with use of a device such as an intramedullary nail that attaches to either the talus or first metatarsal bones to secure the medial cuneiform and navicular bones in place.

First claim

The invention claimed is:

1. A surgical method comprising the steps of:
inserting a first implant into a navicular bone of a foot; and
securing the first implant to the foot with a first threaded connection to a talus bone of the foot.

2. The surgical method of claim 1 , further comprising a step of securing a second implant to the foot, the first implant being attached to the second implant.

3. The surgical method of claim 1 , further comprising a step of securing the first implant to the foot with a second threaded connection to a bone of the foot.

4. The surgical method of claim 3 , wherein the first implant is secured to a first metatarsal of the foot.

5. The surgical method of claim 1 , further comprising a step of inserting a first fastener into a first hole through the first implant, wherein the first fastener provides the first threaded connection.

6. The surgical method of claim 5 , further comprising the steps of:
inserting a second fastener into a second hole through the first implant; and
securing the first implant to the foot with a second threaded connection between the second fastener and a bone of the foot.

7. The surgical method of claim 5 , wherein the first implant is secured with the second threaded connection to a bone of the foot different from the talus bone of the foot.

8. The surgical method of claim 1 , wherein the first implant is an intramedullary nail.

9. A surgical method comprising the steps of:
inserting a first fastener entirely through an intramedullary nail extending within a mid-foot region of a foot and into a first bone in the mid-foot region of the foot to secure the intramedullary nail with a first threaded connection to the first bone; and
securing the intramedullary nail with a second threaded connection to a second bone of the foot different from the first bone.

10. The surgical method of claim 9 , further comprising a step of inserting the intramedullary nail into a plurality of bones of the foot.

11. The surgical method of claim 10 , wherein the plurality of the bones of the foot includes the first and the second bones of the foot.

12. The surgical method of claim 9 , wherein the first bone is a first metatarsal of the foot.

13. The surgical method of claim 9 , wherein the second bone is a medial cuneiform of the foot, a navicular bone of the foot, or a talus bone of the foot.

14. The surgical method of claim 9 , further comprising the steps of:
aligning a first hole extending through the intramedullary nail with a first metatarsal of the foot, a medial cuneiform of the foot, a navicular bone of the foot, or a talus bone of the foot; and
aligning a second hole extending through the intramedullary nail with the first metatarsal of the foot, the medial cuneiform of the foot, the navicular bone of the foot, or the talus bone of the foot.

15. The surgical method of claim 14 , further comprising the steps of:
inserting the first fastener through the first hole; and
inserting a second fastener through the second hole.

16. The surgical method of claim 9 , further comprising a step of inserting an implant into at least one bone of the foot and spaced from the intramedullary nail.

17. A surgical method comprising the steps of:
disposing an entirety of an intramedullary nail in a first plurality of bones of a foot; and
disposing an entirety of a rod in a second plurality of bones of the foot, the rod being spaced from the intramedullary nail.

18. A surgical method comprising the steps of:
disposing an entirety of a first implant in a first plurality of bones of a foot;
disposing an entirety of a second implant in a second plurality of bones of the foot, the second implant being spaced from the first implant; and
securing the first implant to the foot with a first threaded connection by a fastener distinct from the first implant and the second implant.

19. The surgical method of claim 18 , wherein the first implant is an intramedullary nail.

20. The surgical method of claim 18 , further comprising a step of securing the first implant to the foot with a second threaded connection.
