Lisfranc fractures can occur if a heavy object is dropped on the foot or if the foot twists forcefully. This can result from motor vehicle crashes and contact sports. A bone in the joint may break or be forced from its position (dislocate).Lisfranc fractures can cause pain when you stand. You may not be able to stand on your foot or walk. Your foot may swell and bruise and appear deformed. A Lisfranc fracture is commonly mistaken for a sprained foot.
Lisfranc fractures occurs in the bones of the midfoot.
Imaging studies such as X-rays, computed tomography (CT) scans, or magnetic resonance imaging (MRI) scans are used to confirm the fracture location and identify dislocated bones.
The treatment that you receive depends on the extent and severity of your injury. A combination of non-surgical treatments is used if the bones did not dislocate. A cast is placed on the foot to keep it in the proper position while the fracture heals. During this time, you will need to keep weight off your foot and walk with crutches. When the cast is removed, physical therapists will teach you exercises to help you gain motion and strength.
Surgery is used to place dislocated bones in the correct position and stabilize fractures while they heal. Surgical hardware, such as pins, screws, or wires, are placed during surgery to hold the bones in alignment. You will wear a cast and use crutches for about six to eight weeks. After the surgical hardware is removed, you will wear a rigid walking brace or shoe. You may participate in physical therapy to help you move your foot and walk.
