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.
