The Lisfranc fracture is a fracture of the foot in which one or all of the metatarsals are displaced from the tarsus

Tarsus (skeleton)

In tetrapods, the tarsus is a cluster of articulating bones in each foot situated between the lower end of tibia and fibula of the lower leg and the metatarsus. In the foot the tarsus articulates with the bones of the metatarsus, which in turn articulate with the bones of the individual toes...

Causes

This type of injury classically occurred when a horseman fell while riding, having trapped his foot in the stirrup or fallen into a drain. At present, such an injury happens typically in activities such as windsurfing (where participants' feet are in foot straps that pass over the metatarsals), or when one steps into a hole and the foot twists heavily. Falling from a height of two or three stories can also cause this fracture. American football players occasionally get this injury, such as Matt Schaub

Classification

There are three classifications for the fracture:

1. Homolateral: All 5 metatarsals are displaced in the same direction. Lateral displacement may also suggest cuboidal fracture
2. Isolated: 1 or 2 metatarsals are displaced from the others
3. Divergent: metatarsals are displaced in a sagittal or coronal plane. May also involve intercuneiform area and a navicular fracture.

Treatment

Treatment options include operative or non-operative treatment. If the dislocation is less than 2 mm, the fracture can be managed with casting for 6 weeks. The patient's injured limb cannot bear weight during this period. For operative treatment, screws +/- k-wire will be used for internal fixation of the fracture after closed or more likely open reduction. Again, the patient's injured limb should not bear weight for approximately 6–12 weeks. The screws/k-wires are usually removed later, sometimes before weight bearing

Weight bearing

In orthopedics, weight-bearing is the amount of weight a patient puts on the leg on which surgery has been performed. In general, it is described as a percentage of the body weight, because each leg of a healthy person carries the full body weight when walking, in an alternating fashion.After...
