What Is the Lisfranc Fracture?
A break in a bone in the Lisfranc joint can be either an avulsion fracture a small piece of bone is pulled off or a break through the bone or bones of the midfoot. The Lisfranc 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 Lisfranc 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.
How Do Lisfranc Fracture Occur?
Injuries to the Lisfranc joint most commonly occur in automobile accident victims, military personnel, runners, horseback riders, football players and participants of other contact sports, or something as simple as missing a step on a staircase. Lisfranc fractures occur as a result of direct or indirect forces to the foot. A direct force often involves something heavy falling on the foot. Indirect force commonly involves twisting the foot.
Other Types of Lisfranc Injuries
There are three types of Lisfranc injuries, which sometimes occur together:
- Sprains. The Lisfranc ligament and other ligaments on the bottom of the midfoot are stronger than those on the top of the midfoot. Therefore, when they are weakened through a sprain (a stretching of the ligament), patients experience instability of the joint in the middle of the foot.
- Dislocations. The bones of the Lisfranc joint may be forced from their normal positions.
Symptoms of a Lisfranc Fracture or injury may include:
- Swelling of the foot
- Pain throughout the midfoot when standing or when pressure is applied
- Inability to bear weight (in severe injuries)
- Bruising or blistering on the arch are important signs of a Lisfranc injury. Bruising may also occur on the top of the foot.
- Abnormal widening of the foot.
