Transverse tarsal joint
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. 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 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.

The movement which takes place in this joint is more extensive than that in the other tarsal joints, and consists of a sort of rotation by means of which the foot may be slightly flexed or extended, the sole being at the same time carried medially inverted or laterally everted.
