A Lisfranc injury involves the joints and/or the ligaments of the middle of the foot. The Lisfranc ligament is a ligament of the foot that runs between two bones called the medial cuneiform and the second metatarsal. The name comes from French surgeon Jacques Lisfranc de St. Martin (1790-1847), who was the first physician to describe injuries to this ligament.
There are a variety of causes for this injury such as a car accident, sports injury, or a simple slip and fall. Sometimes the injury can be mistaken for a foot sprain when X-rays do not show any broken bones. Delaying treatment can sometimes lead to more significant problems. The key for the treatment of a Lisfranc injury is proper diagnosis.
