The Lauge-Hansen classification does not cover all types of ankle injuries. The present report details three cases of exceptional fragment of the medial tibia that differed from the traditional Lauge-Hansen supination–external rotation and pronation–external rotation fracture patterns. The information obtained from this study will be helpful for conducting basic research of this condition and determining appropriate surgical approaches.
