We present two cases of ankle arthrodesis in which tibiotalar fixation was achieved by two cancellous-bone screws across the ankle joint and a lateral fibular strut graft fixed with a proximal and a distal screw. This operation is a technique described by Thordarson and his associates, who performed only an in vitro biomechanical study using fresh-frozen cadaver. Through the recent clinical trial, we could get excellent results in both of our cases. We feel the fibular strut graft provides additional stability to tibiotalar internal fixation. This technique may have a special value for those cases with poor bone quality or osteoporosis.
