Lisfranc Fracture

Midfoot is the middle region of the foot which forms an arch on the top of the foot.

It is cluster of small bones which are held in place by ligaments. A severe injury (motor vehicle accidents, contact sports injury), fall from heights or direct blow due to fall of heavy object can break or dislocate these bones out of place. The midfoot is critical in stabilizing the arch and transferring the forces generated by the calf muscles to the front of the foot while walking.

The midfoot joint complex is also called the Lisfranc joint. It is named after French surgeon Jacques Lisfranc de St. Martin, who served in the Napoleonic army in the 1800s. The Lisfranc joint complex has a specialized bony and ligamentous structure, providing stability to this joint.

Lisfranc (midfoot) injuries result if bones in the midfoot are broken or ligaments that support the midfoot are torn. The severity of the injury can vary from simple to complex, involving many joints and bones in the midfoot.

A Lisfranc injury is often mistaken for a simple sprain, especially if the injury is a result of a straightforward twist and fall. However, injury to the Lisfranc joint is not a simple sprain that should be simply “walked off.” It is a severe injury that may take many months to heal and may require surgery to treat.

Some never return to their pre-injury levels of activity after these injuries. Despite excellent surgical reduction and fixation, arthritis may occur from the damage to the cartilage. This may result in chronic pain and may require fusion in the future.
