Bunion repair using suture-button construct
First Claim
Patent Images
1. A method of bunion repair comprising:
- drilling a hole across a first metatarsal and through a second metatarsal;
passing a needle with a first suture strand of a suture-button construct through the hole;
pulling the first suture strand and simultaneously applying a lateral tension on a second 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 through a medial side of the first metatarsal cortex;
flipping the first button to engage the first button against the first metatarsal and applying a lateral tension on the second suture strand;
manually pushing the first metatarsal and the second metatarsal together to correct intermetatarsal angular deformity;
pulling free ends of the second suture strand of the suture-button construct to advance a second button of the suture-button construct and to engage the second button against the second metatarsal; and
securing the second button against the second metatarsal.

Abstract
A method for bunion repair using a suture-button construct. The suture-button construct includes a first button, a second button, a first suture strand, a pull-through suture strand and a needle. The first and second buttons have apertures to facilitate the suture strands to pass through the buttons. The first suture strand is double looped through the first and second buttons and the pull-through suture strand is looped through one of the apertures of the first button. The pull-through suture strand also loops through an eyelet of the needle and thus, is operatively associated with the needle. A suture anchor-button construct can also be used for bunion repair.

-
drilling a hole across a first metatarsal and through a second metatarsal; passing a needle with a first suture strand of a suture-button construct through the hole; pulling the first suture strand and simultaneously applying a lateral tension on a second suture strand of the suture-button construct such that a first button of the suture-button construct lies sideways, and advancing the first button laterally through the hole until the first button exits the hole through a lateral side of the second metatarsal cortex; flipping the first button to engage the first button against the lateral side of the second metatarsal and applying a lateral tension on the second suture strand; manually pushing the first metatarsal and the second metatarsal together to correct intermetatarsal angular deformity; pulling free ends of the second suture strand of the suture-button construct to advance a second button of the suture-button construct and to engage the second button against the medial side of the first metatarsal; and securing the second button against the first metatarsal.
