Lisfranc Injury

A lisfranc injury, also known as a lisfranc fracture, is a foot injury involving one or more of the five metatarsal bones in the midfoot region. These injuries commonly occur in sports such as football, soccer, or lacrosse. A strain of the flexed Lisfranc joint may occur simply from tripping over a foot. Excessive force applied to the area can cause either a sprain or fracture. Localized trauma, including both direct and indirect injury, can cause this condition. Direct trauma might include a heavy object falling onto the top of the foot or a foot being run over by a vehicle. Indirect trauma is caused by a sudden rotational force on a downward pointed forefoot. Participants in extreme sports, including windsurfing, wakeboarding, or snowboarding may also commonly experience this type of injury.

Pain may occur as a result when standing or when pressure is applied to the midfoot. Bruising may also occur on the top of the foot.

Several variations of a lisfranc injury may occur. A proper diagnosis will involve an examination by a foot and ankle doctor and X-ray images. The diagnosis will confirm whether all five metatarsal bones are displaced in a similar direction, one or two are displaced from the others, or a divergent classification that might also include a navicular fracture.

For less serious dislocation of the affected bones, your physician may prescribe casting or bracing for several weeks. During this period, you will not be able to bear weight on the limb and may require crutches. For severe cases, surgery is necessary to perform an open reduction internal fixation. Hardware will be installed during this procedure to hasten healing. Screws or wires may be removed several weeks after surgery once the injury has healed to a point of stability. A non-weight-bearing period will follow surgery, with a gradual easing back to weight-bearing over the course of several weeks.
