Lisfranc fracture

Lisfranc fracture is almost always accompanied by dislocation of the Lisfranc joints or the tarsometatarsal joints that are located in the middle of the foot. A twisting fall or a heavy blow can cause this fracture. Connective tissues or ligaments hold the bones in place. The first and second metatarsals are not held by any connective tissue. Hence when a twisting fall occurs, dislocation of these bones takes place. Due to this injury the tarsal bones are dislocated, but (MT) does not occur always. Generally, the fracture and the dislocation are treated independently with stabilization devices. One or more of the tarsometatarsal joints are dislocated when Lisfranc dislocation occurs.

Many times, mistaken for sprains, Lisfranc fractures are associated with swelling of the top of the foot which is also very painful. It is very difficult to put any weight on the foot if the injury is very severe. Often X-rays do not reveal Lisfranc injuries. Serious complications like joint degeneration and compartment syndrome will follow when Lisfranc injuries go unrecognized. If the pain or swelling does not reduce in spite of normal treatment for a sprain, it is better to take the advice of an orthopaedic specialist.

By examining the foot for signs of injury, an orthopedist will move the foot in a circular motion holding the heel steady. A CT scan or MRI scan will show the exact nature of the injury. Open Reduction Internal Fixation (OR IF) is advised for dislocation.
