A modification of Chopart's amputation with ankle and subtalar arthrodesis by using an intramedullary nail.
This study reports on 7 patients who underwent a new technique for Chopart amputation that includes ankle and subtalar arthrodesis using an intramedullary nail. This method affords rigid control to the rearfoot and appears to avoid the most common complications historically associated with Chopart amputations. All 6 surviving patients achieved successful outcomes within 1 year of their surgery. All are community ambulators who are able to walk short distances within the home without a prosthesis. One patient, who had undergone a previous vascular bypass, died in the early postoperative period after developing an infection that required an above-knee amputation. A second patient developed an infection that resolved with intravenous antibiotics. This new technique reintroduces the Chopart-level amputation as a valuable intermediate between the transmetatarsal and below-knee amputation levels.
