What is a Lisfranc Joint Injury?
The Lisfranc joint is located in the middle of the foot, creating the arch. There are many small bones and ligaments that make up this joint. Because of this, an injury that damages even one bone or ligament in this region can affect several others.
A Lisfranc joint injury may be caused by a sprain of the main supportive ligament in this region, known as the oblique interosseous ligament. Unlike a simple sprain, an injury to the oblique interosseous ligament can be more serious and lingering. An injury to the middle of the foot may also cause a dislocation of the Lisfranc joint. One or more bones may also break at the area where they connect at the Lisfranc area. A Lisfranc joint injury may be caused by a direct impact to the region, such as during a car accident. An injury to the middle of the foot may also occur from indirect impact, such as during a fall when there is also a twisting of the foot.
