[Calcaneo-fibular ligament surgery for chronic lateral instability of the upper ankle : Broström technique with modification by Wille. Video article].

Background An acute ligament rupture of the lateral ligament complex of the ankle joint is treated without surgery. Treatment failure may lead to a chronically unstable situation of the ankle joint, in which case surgery is an effective procedure for stabilizing the ruptured ligaments. Anatomical reconstruction is the best operative technique if the ligament tissue is of good quality. Method In our video we demonstrate a new possibility for the positioning of an anchor to tighten the calcaneo-fibular ligament. Modified Brostrom repairs are described in the literature in which the calcaneo-fibular ligament is released and reattached to the fibula to tighten it. We present the option to release the ligament at the calcaneus and reattach it using a suture anchor. This offers the advantage of preventing the possible dislocation of the peroneal tendons.
