 Lisfranc joint injuries usually refer to fractures or dislocations of the tarsometatarsal joint complex. The Lisfranc joint consists of 3 parts: the medial column, middle column and lateral column. The medial column is formed by the base of the 1st metatarsal and the medial cuneiform, the middle column is formed by the bases of the 2nd and 3rd metatarsals and the middle and lateral cuneiforms, and the lateral column is formed by the bases of the 4th and 5th metatarsals and the cuboids. Injuries can be caused by direct or indirect forces. The spectrum of injuries ranges from low energy sports injuries to high energy injuries. The 2 most common injury mechanisms: high energy injuries caused by motor vehicle accidents and low energy injuries caused by falls from height. Quénu and Kuss divided Lisfranc injuries into 3 categories: isolated, homolateral, and divergent injuries. The Myerson classification continues to be used today, which plays an important role in treating instable and comminuted fractures. The Lisfranc joints provide the bony structural support for the transverse arch in the midfoot, and the injuries account for approximately 0.2% of that all over the body. Early diagnosis is critical to preserve normal foot function and biomechanics performance. However, up to 20% of Lisfranc injuries are misdiagnosed or missed at present. If such injuries were overlooked or not treated correctly, painful malunion and impaired function would appear, often accompanying by vascular injuries. Therefore, strong vigilance of Lisfranc injuries must be emphasized when evaluating any patient complaining of midfoot pain or any multi-wounded patient. The main clinical features may be the plantar ecchymosis and pain. In patients with a high index of suspicion, the passive abduction and pronation of the forefoot should be performed on the premise of assuring the hindfoot stable. The purpose of the present review was to explain the anatomy and diagnosis of Lisfranc joint injuries, based on which Lisfranc injuries could be diagnosed timely and be treated correctly by clinical surgeons.
