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

I claim:

1. A surgical method comprising the steps of:
inserting an implant into a first metatarsal and a medial cuneiform of a foot; and
securing the implant to the foot with a threaded connection to the first metatarsal.

2. The method of claim 1 , further comprising the step of compressing the medial cuneiform and the first metatarsal of the foot.

3. The method of claim 2 , further comprising the step of performing a closed reduction of the medial cuneiform and the first metatarsal of the foot under fluoroscopy.

4. The method of claim 1 , further comprising a step of aligning an opening extending through the implant with either or both of the medial cuneiform and the first metatarsal of the foot.

5. The method of claim 4 , further comprising the step of disposing a first fastener through the opening, wherein the first fastener provides the threaded connection to the first metatarsal to secure the implant to the foot.

6. The method of claim 1 , further comprising inserting the implant into a talus bone of the foot.

7. The method of claim 1 , further comprising a step of reaming a medullary canal within the medial cuneiform and the first metatarsal of the foot.

8. The method of claim 7 , further comprising the steps of:
reaming a medullary canal within a talus bone of the foot; and
inserting the implant into the talus bone of the foot.

9. The method of claim 1 , wherein a first fastener provides the threaded connection to the first metatarsal to secure the implant to the foot, further comprising a step of securing the implant to the foot with a second fastener.

10. The method of claim 9 , wherein the securing steps include disposing the first fastener in any one or any combination of the medial cuneiform of the foot, a navicular bone of the foot, and a talus bone of the foot, and disposing the second fastener in any one or any combination of the other of the first metatarsal, the medial cuneiform, the navicular bone, and the talus bone.

11. The method of claim 1 , wherein the implant is a first implant, further comprising the step of inserting a second implant into the foot, the second implant being spaced apart from the first implant.

12. The method of claim 1 , wherein the implant is further secured to the foot with a threaded connection to a talus bone of the foot.

13. The method of claim 1 , wherein the implant is inserted into an end of the first metatarsal of the foot opposite the end of the first metatarsal adjacent to the medial cuneiform of the foot.

14. The method of claim 1 , wherein a first fastener includes a threaded head that provides the threaded connection to the first metatarsal to secure the implant to the foot.

15. A surgical method comprising the steps of:
inserting a first implant into a foot such that the first implant lies within each of a first metatarsal, a medial cuneiform, a navicular bone, and a talus bone of the foot; and
attaching, directly, a second implant to the first implant and to the foot.

16. A surgical method comprising the steps of:
securing a first fastener in a first metatarsal of a foot through a first opening formed in an implant; and
securing a second fastener in a medial cuneiform, a navicular bone, or a talus bone of the foot through a second opening formed in the implant.

17. The method of claim 16 , further comprising inserting the implant into the first metatarsal and the one of the medial cuneiform, the navicular bone, and the talus bone of the foot to which the second fastener is secured.

18. The method of claim 16 , further comprising the steps of reaming medullary canals within the first metatarsal and the one of the medial cuneiform, the navicular bone, and the talus bone of the foot to which the second fastener is secured.

19. The method of claim 16 , wherein the securing step includes threading either or both of the first fastener into the first opening and the second fastener into the second opening.

20. The method of claim 16 , further comprising positioning the implant adjacent to bones in the foot such that the implant defines an axis in a same plane as a longitudinal axis defined by a metatarsal of the foot.

21. A surgical method comprising the steps of:
inserting an implant into a foot; and
securing the implant to the foot with a threaded connection to a first metatarsal of the foot and attachment of the implant to at least a second bone of the foot different from the metatarsals and phalanges of the foot.

22. The method of claim 21 , wherein the attachment of the implant to the second bone of the foot is a threaded connection to a medial cuneiform, a navicular bone, or a talus bone of the foot.
