Abstract

Claims (33)

1. A method of preparing a metatarsophalangeal joint for fusion, the method comprising:

preparing a distal end of a metatarsal for fusion;

preparing a proximal end of an opposed phalanx for fusion, the opposed phalanx being separated from the metatarsal by a metatarsophalangeal joint;

moving the opposed phalanx relative to the metatarsal in a frontal plane and a sagittal plane;

using an instrument engaged with the metatarsal and engaged with the opposed phalanx to compress a prepared end of the metatarsal together with a prepared end of the opposed phalanx; and

applying a bone fixation device to the metatarsal and the opposed phalanx across the metatarsophalangeal joint.

2. The method of claim 1 , further comprising moving the opposed phalanx relative to the metatarsal in a transverse plane.

3. The method of claim 1 , wherein:

preparing the end of the metatarsal comprises reaming the end of the metatarsal with a generally conical-shaped reamer; and

preparing the end of the opposed phalanx comprises reaming the end of the opposed phalanx with a generally cone-shaped reamer.

4. The method of claim 1 , further comprising, prior to applying the bone fixation device, provisionally fixing a moved position of the opposed phalanx relative to the metatarsal.

5. The method of claim 4 , wherein provisionally fixing the moved position of the opposed phalanx relative to the metatarsal comprises provisionally fixing the moved position of the opposed phalanx with a pin.

6. The method of claim 1 , wherein the bone fixation device comprises one or more of a screw, a bone plate, and a staple.

7. The method of claim 1 , further comprising inserting a pin into the opposed phalanx, wherein moving the opposed phalanx comprises moving the opposed phalanx via the pin.

8. The method of claim 1 , further comprising moving the metatarsal to establish a moved position of the metatarsal prior to applying the bone fixation device to the metatarsal and the opposed phalanx.

9. The method of claim 8 , wherein moving the metatarsal comprising moving the metatarsal in at least the transverse plane and the frontal plane.

10. The method of claim 1 , further engaging the instrument with the metatarsal via a first pin inserted into the metatarsal and with the opposed phalanx via a second pin inserted into the opposed phalanx.

11. The method of claim 1 , wherein the instrument comprises a compressor-distractor.

12. The method of claim 1 , wherein preparing the metatarsophalangeal joint for fusion comprises treating the metatarsophalangeal joint for arthritis.

13. The method of claim 1 , wherein the metatarsal is a first metatarsal.

14. A method of preparing a metatarsophalangeal joint for fusion, the method comprising:

surgically accessing a metatarsophalangeal joint separating a first metatarsal from a proximal phalanx;

reaming an end of the first metatarsal with a generally conical-shaped reamer;

reaming an end of the proximal phalanx with a generally cone-shaped reamer;

moving the proximal phalanx relative to the first metatarsal in a sagittal plane;

using an instrument engaged with the first metatarsal and engaged with the proximal phalanx to compress a prepared end of the first metatarsal together with a prepared end of the proximal phalanx; and

applying a bone fixation device to the first metatarsal and the proximal phalanx across the metatarsophalangeal joint.

15. The method of claim 14 , further comprising moving the proximal phalanx relative to the first metatarsal in a frontal plane.

16. The method of claim 14 , further comprising moving the proximal phalanx relative to the first metatarsal in a transverse plane.

17. The method of claim 14 , further comprising, prior to applying the bone fixation device, provisionally fixing a moved position of the proximal phalanx relative to the first metatarsal.

18. The method of claim 17 , wherein provisionally fixing the moved position of the proximal phalanx relative to the first metatarsal comprises provisionally fixing the moved position of the proximal phalanx with a pin.

19. The method of claim 14 , wherein the bone fixation device comprises one or more of a screw, a bone plate, and a staple.

20. The method of claim 14 , wherein preparing the metatarsophalangeal joint for fusion comprises treating the metatarsophalangeal joint for arthritis.
