Lisfranc Fracture: Typically consists of a fracture of the base of the second metatarsal and dislocation, though it can also be associated with fractures of a cuboid.

Pearls:
  • Fracture findings on plain films may be subtle.
  • If in doubt obtain weight bearing AP views of the foot to demonstrate dislocation/fracture.
  • If weight bearing films are negative and you are still suspicious consider a CT scan of the foot.

Additional Information

Lisfranc Fracture:

Common current mechanism of injury is when a person steps into a hole and twists the foot.  The original mechanism of injury that was described was when a horseman would fall of their horse with their foot still trapped in a stirrup.

Diagnosis should be considered if patient has difficultly weight bearing with pain on palpation over the 2nd and 3rdmetatarsals with an appropriate mechanism.
