The Lisfranc joint is the point at which your 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 these two bones. This ligament is important for maintaining proper alignment and strength of the joint.
There are three types of Lisfranc injuries, which sometimes occur together:
Injuries to the Lisfranc joint most commonly occur in car accidents, military activities, contact sports, or small accident such as missing a step on a staircase. Lisfranc injuries 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.
Symptoms of a Lisfranc injury may include:
Lisfranc injuries are sometimes mistaken for ankle sprains, making the diagnostic process very important. To arrive at a diagnosis, we will determine how the injury occurred and examine the foot to determine the severity of the injury. X-rays and other imaging studies may be necessary to fully evaluate the extent of your injury. We may also perform an additional examination while you are under anesthesia to further evaluate any fractures or weakening of the joint and surrounding bones.
Certain types of Lisfranc injuries may require surgery. We will determine the type of procedure that is best suited for you.
