Abstract

An apparatus and method for Lisfranc repair using a suture-button construct. The method includes the steps of drilling a hole in a medial cuneiform and through a second metatarsal base, passing a needle with a pull-through suture strand through the hole, pulling the pull-through suture strand and simultaneously applying a lateral tension on a first suture strand such that the first button lies sideways and advancing the first button through the hole until the it exits the hole at the medial cuneiform, flipping the first button to engage it against the medial aspect of the medial cuneiform and applying a lateral tension on the first suture strand, pulling free ends of the first suture strand to advance a second button over the second metatarsal base and to engage it against the second metatarsal base, and securing the second button against the second metatarsal base by tying a Surgeon's knot and two reverse half-hitches.

Claims (11)

1. A method of Lisfranc repair comprising:

drilling a hole in a medial cuneiform and through a second metatarsal base;

passing a needle with a pull-through suture strand of a suture-button construct through the hole, the needle entering the hole from the second metatarsal base and exiting the hole out of the medial cuneiform;

pulling the pull-through suture strand and simultaneously applying a lateral tension on a first suture strand of the suture-button construct such that a first button of the suture-button construct lies sideways, and advancing the first button through the hole until the first button exits the hole at the medial cuneiform;

flipping the first button to engage the first button against the medial aspect of the medial cuneiform and applying a lateral tension on the first suture strand;

pulling free ends of the first suture strand of the suture-button construct to advance a second button of the suture-button construct over the second metatarsal base and to engage the second button against the second metatarsal base; and

securing the second button against the second metatarsal base.

2. The method of claim 1 , wherein the first button is oblong-shaped having at least two apertures, the at least two apertures being substantially triangular in shape.

3. The method of claim 1 , wherein the second button is round-shaped having at least four apertures, the at least four apertures being substantially circular-shaped and centers of the at least four apertures being substantially equi-distant from a center of the second button.

4. The method of claim 1 , wherein the first suture strand and the pull-through suture strand comprise a plurality of fibers of ultrahigh molecular weight polyethylene.

5. The method of claim 1 , further comprising the initial step of making a dorsal longitudinal incision over medial border of foot overlying medial cuneiform.
