The Lis Franc (midfoot joint) joint is the point at which the metatarsal bones (long bones that lead up to the toes) and the tarsal bones (bones in the arch) connect. The Lis Franc ligament is a tough band of tissue that joins two of these bones. This is important for maintaining proper alignment and strength of the joint. This is one of the most common missed injuries in the foot.
Complications can often arise following Lis Franc injuries. One possible early complication following the injury is compartment syndrome, in which pressure builds up within the tissues of the foot. This is a medical emergency, and an immediate surgery is required to prevent tissue damage. The build-up of pressure could cause permanent damage to nerves, blood vessels, and muscles in the foot. Arthritis and problems with foot alignment are very likely to develop if this injury is not treated properly. Arthritis can develop several months or longer following a Lis Franc injury, requiring additional treatment. A foot and ankle surgeon can determine the best treatment course for patients, as treatment plans can vary in every scenario.
Lis Franc fracture surgery is usually an outpatient (same day) surgical procedure. The surgery can be performed under General Anesthesia. Post-operatively, the foot is placed in a short leg cast.
If surgery is needed, the fracture is reduced (reposition the fracture) into a normal alignment and position, then screws, plates, and or wires will be used to hold the bone fragments together while they heal. In severe cases, an external fixator (fixation on the outside of the body) may be uses for fixation in order to stabilize the bone. Usually, it takes 6-8 weeks for the bone to heal.
Patients will be non weight bearing after surgery. Most patients only experience pain for about 2-5 days after surgery, but everyone is different. Bone fracture usually heal within 6-8 weeks.
