Apparatus and method for fixation of ankle syndesmosis
First Claim
1. An ankle syndesmosis tibio-fibular diastasis fixation apparatus, the apparatus comprising a kit of parts comprising first and second buttons, in which each of the first and second buttons has at least first and second apertures;
- a flexible coupling mounted, in use, between the first and second buttons, in which the flexible coupling is a first suture which is fed, in use, through the second aperture of the second button and through, in turn, the second and first apertures of the first button and through the first aperture of the second button; and
a needle secured to the first button, in which the needle is secured to the first button by a second suture, the second suture being looped through one of the first or second apertures of the first button and operatively associated with the needle.

Abstract
The present invention relates to an apparatus and method for the fixation of ankle syndesmosis tibio-fibular diastasis, the apparatus comprising a pair of buttons secured together by means of a first suture, a second suture being secured to one of the pair of buttons, and to a needle, such that the needle and associated button, the first button, may be advanced through a hole drilled through the fibula and tibia, adjacent the ankle, wherein the first button and second button may then be tightened against either side of the ankle sydesmosis, by means of the first suture connected therebetween, to prevent diastasis of the ankle syndesmosis.
