[edit] Discussion of Lisfranc fracture-dislocation

  • Fracture-dislocation or fracture-subluxation of the tarsometatarsal joints, typically the second through the fifth joints with lateral displacement of the metatarsals.
  • It is named for Lisfranc, a surgeon in Napoleon's army who described an amputation method through the tarsometatarsal joints. His technique saved a portion of the foot after distal injury or frostbite.
  • Any patient with a Lisfranc fracture, or dislocation in the absence of acute trauma, should undergo evaluation for diabetes mellitus and other causes of sensory neuropathy.
  • Operative treatment is usually needed in patients with a Lisfranc fracture–dislocation to achieve anatomic reduction and fixation.
