Lisfranc injuries in athletes have been classified according to the American Medical Association’s Standard Nomenclature of Athletic Injuries. First- and second-degree sprains have been classified as partial ligament tears with swelling, focal pain, no instability, and normal radiographs. Instability and diastasis greater than 2 mm between the first and second metatarsals (MTs), as seen on anteroposterior (AP) radiographs, is consistent with a third-degree sprain. [7, 8]
