Abstract

A button and attached suture loop for CMC repair. A suture strand is threaded through holes in the button to attach the button to the suture. The suture ends are then brought together (by being swaged, spliced or cinched together, for example) to form the suture loop comprising a continuous, uninterrupted suture loop with a single strand of swaged-together ends. The swaged-together ends are attached to a suture passing instrument such as a K-wire (Kirschner wire) that is also used to drill a hole through adjoining metacarpals (for example, the first and second metacarpals). The swaged-together ends of the suture are then passed through the drill holes in the first and second metacarpals, and the ends of the suture are pulled until the button abuts one of the first and second metacarpals. A second button is used to secure the cut suture ends to the other metacarpal.

First claim

What is claimed is:

1. A method of carpometacarpal repair, comprising the steps of:
drilling a hole through a first metacarpal and a second metacarpal;
providing a button/loop construct comprising a button with at least a pair of apertures, and a continuous flexible strand loop connected to the button by passing the flexible strand through the apertures, with opposing ends of the flexible strand terminating in a combined leg;
passing the combined leg and the loop of the button…
