Lisfranc's ligament connects the medial cuneiform bone (one of the tarsals) to the base of the 2nd metatarsal. The injury may consist of a dislocation where there is only ligament damage, or a fracture of one of the two bones may also occur.
The term Lisfranc's joint refers to the tarsometatarsal joints where the long bones (tarsals) in the foot meet the smaller bones (metatarsals) of the toes. Jaques Lisfranc was a surgeon in Napoleon's Army who described an operation for an amputation through this joint.
Lisfranc's injury or Lisfranc's fracture-dislocation is rare in sport, but, if left untreated, can have very severe consequences. If a case of midfoot sprain is suspected then Lisfranc's injury should also be considered.
The most common cause of this injury is stepping into a small hole, which causes a strong twisting force with a lot of body weight on top. It can also happen in car accidents.
