During walking, the midfoot transfers the forces generated by the calf muscles to the front of the foot.The midfoot joint complex is also called the Lisfranc joint.The bones are held in place by connective tissues (ligaments) that stretch both across and down the foot.However, there is no connective tissue holding the first metatarsal to the second metatarsal.A Lisfranc injury is often mistaken for a simple sprain, especially if the injury is a result of a straightforward twist and fall.However, injury to the Lisfranc joint is not a simple sprain that should be simply "walked off." It is a severe injury that may take many months to heal and may require surgery to treat.Lisfranc injuries include ligament strains and tears, as well as fractures and dislocations of bone (far right).The midfoot is critical in stabilizing the arch and in walking (gait).
In this case, the doctor is looking for a ligament injury, especially if the bones are not expected to be broken.
A twisting fall can break or shift (dislocate) these bones out of place.
The Lisfranc joint complex includes the bones and ligaments that connect the midfoot and forefoot.
After talking with you about your symptoms and discussing your concerns, your doctor will examine your foot and ankle.
Although some of the physical tests the doctor will perform may be painful, none of them will make the injury worse.
