Below the knee cast

The below the knee cast may be used for:

  • Distal tibial fractures
  • Ankle fractures and dislocations
  • Foot fractures
  • Serial/deformity casting

The ankle should be immobilized at a 90° angle; patients may inadvertently plantar flex their foot during casting. Because it will rest on the ground, a good foot plate, flat, with extra layers of cast material, is also essential. The cast should not impede range of motion at the knee.
