Lisfranc injury

Ligamentous and bony injury of the tarsometatarsal joints, frequently mistaken for a sprain.

The injury

Disruption of the ligaments and joints between the metatarsals and the tarsal bones. The mechanism may be a twisting fall on a planted foot, a pedal injury in a road traffic collision, or an apparently minor sprain that fails to settle. The injury is readily missed on initial radiographs.

Diagnosis

Weight-bearing radiographs of both feet, supplemented by CT or MRI where the diagnosis remains uncertain. Plantar bruising is a recognised sign.

Treatment

Displaced injuries are stabilised operatively. The joints are reduced through one or two dorsal incisions and held with transarticular screws or with plates that bridge the joints. Purely ligamentous injuries are sometimes treated by primary fusion, as the ligament heals poorly.

Recovery: points specific to this injury

Six weeks non-weight-bearing is usual, followed by a boot. Bridging plates are commonly removed at four to six months, once the ligaments have healed.

Recovery after surgery

The timeline below is a typical pathway after fracture surgery. The exact plan depends on the injury and the fixation, and will be confirmed at each review.

StageWhat to expect
Weeks 0–2A temporary cast is applied and the leg must be kept non-weight-bearing. During this period the limb should be elevated, with the toes above the level of the nose, ideally for 55 minutes out of every hour, to help control swelling. You can mobilise with crutches, a knee scooter or an iWALK hands-free crutch (see recovery equipment).
At 2 weeksIf possible, the cast is changed to a boot so that soft-tissue management can begin: desensitisation, and moisturising of the scars. Creams such as Kelo-cote or castor oil can be used for wound care (see recovery equipment). If a boot is not yet appropriate, a further cast is applied from week 2 to week 6.
At 6 weeksThe cast is removed and you move into a boot, typically a short surgical boot where possible, or a Vacoped boot, depending on the type of surgery.
PhysiotherapyPhysiotherapy starts as soon as the limb is accessible, which is either at 2 weeks or at 6 weeks.
ExerciseCore and upper-body work can start as soon as the cast has been removed and you are in a boot, which can be as early as week 2, but with nothing through the injured limb. From 6 weeks, gentle range-of-motion exercise can begin, such as a cross-trainer, a fixed (static) bike and swimming. Impact sports such as running and jumping can normally start at 12 weeks; this depends to some extent on the fracture configuration.
Longer termThese are often complex and severe injuries. Improvement can take up to 18 months to reach a new baseline. Swelling often persists for months, typically around 9 to 12 months, and some swelling often persists lifelong, without complete resolution of the ankle swelling.

Risks of surgery

The risks associated with this surgery include, but are not limited to:

  • Pain
  • Bleeding
  • Infection
  • Scarring
  • Damage to nerves and blood vessels
  • Deep vein thrombosis (DVT) — a blood clot in the veins of the leg
  • Pulmonary embolism (PE) — a blood clot that travels to the lungs, which can be life-threatening
  • Stiffness
  • Non-union — failure of the bone to heal
  • Malunion — the bone healing in an incorrect position
  • The need for further surgery, such as removal of metalwork

These risks are discussed individually before surgery.
