Abstract
A technique and associated instrumentation for correcting large intermetatarsal angles that result from hallux valgus. The system includes a button and a suture loop attached to the button. 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 may be attached to a suture passing instrument such as a K-wire (Kirschner wire) that may be further used to drill a hole through the first and second metatarsals. The swaged-together ends of the suture are then passed through the drill holes in the first and second metatarsals; and the ends of the suture are pulled until the button abuts the second metatarsal. The swaged together portion of the suture loop is then cut, and the free suture ends are passed through holes in another (second) button. The suture ends are pulled to adjust the first metatarsal to a correct intermetatarsal angle, and the first metatarsal is secured in place by tying the ends of the sutu…
