What is the Lisfranc Joint?
The Lisfranc joint is the point where the metatarsals (foot bones) and the tarsals (bones that make the arch of the foot) connect. (See diagram below)
How Do These Injuries Occur?
Lisfranc injuries typically occur as a result of trauma, either directly, such as a heavy object falling on the foot, or indirectly, like twisting the foot. These injuries are common in vehicle accident victims, military personnel, runners, horseback riders, and hard contact sports players.
Types of Lisfranc Injuries
- Sprains: A stretching of the Lisfranc ligament
- Fractures: A break in one of the bones of the Lisfranc joint
- Dislocations: In which the bones of the Lisfranc joint are forced out of their natural positions
Signs and Symptoms
- Swelling of the foot
- Pain throughout the middle of the foot when standing
- Inability to bear weight in more extreme injuries
- Bruising or blistering on the arch. Bruising can also occur on the top of the foot
- Abnormal widening of the foot
Your podiatrist will ask you how the injury occurred, along with a thorough examination of the foot to determine how severe the injury is. X-rays, CT scans, or MRIs might be needed to fully evaluate the extent of the injury.
