Pilon fracture

High-energy fracture of the weight-bearing surface of the distal tibia; treatment is usually staged.

The injury

A high-energy fracture of the weight-bearing surface of the distal tibia, typically following a fall from height or a road traffic collision. The articular surface is often multifragmentary and the overlying soft tissues are frequently compromised.

Why treatment is staged

Operating through swollen or contused skin carries a substantial risk of wound breakdown and deep infection. The first procedure, undertaken within a day or two, is commonly a spanning external fixator that restores length and allows the soft tissues to settle. Definitive fixation follows once the skin wrinkle sign has returned, usually after seven to fourteen days.

Definitive fixation

A CT scan is used to map the fragments. The articular surface is reconstructed and supported with anatomically contoured medial and anterolateral tibial plates, with fibular fixation where indicated. Limited incisions are used where the fracture pattern allows.

Recovery: points specific to this injury

Recovery is longer than after an isolated ankle fracture: typically six weeks non-weight-bearing and a boot until approximately twelve weeks. Some residual stiffness is to be expected and physiotherapy is an important determinant of the final result. Post-traumatic arthritis may develop in later years; this is discussed before surgery.

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.
