Lisfranc fracture or Lisfranc injury as it is now often called is an injury where at least one of the metatarsals is separated from the tarsal. This typically occurs as a fracture and dislocation but can be only a dislocation.
This injury is named for Jacques Lisfranc de St. Martin, a field surgeon in Napoleons army. He would perform amputations along the tarsal metatarsal line because this allowed soldiers to return to combat much sooner.
During the Napoleonic wars cavalry soldiers would fall of their horses but one foot would remain in the stirrup. As the horse would continue to move the weight of the body would twist the foot in such a way that the tarsal metatarsal joint would become stressed and a fracture dislocation would occur.
In today’s world we don’t see many Lisfranc injuries but they do occur. This can occur with sports, typical football, or as a result of an accident. The foot becomes stuck in a position where the forefoot is held in place and the body moves in another direction.
The Lisfranc injury takes a long time to recovery. It is more uncomfortable and has a longer impact then most ankle sprains. Because it occurs in the foot and the mechanism of injury is often similar to an ankle sprain. It can be initially misdiagnosed as an ankle sprain.
