Using Box Splints for Lower Limb Fractures

Overview of Box Splints

Understanding the components and application of box splints for stabilising lower limb fractures.

Key Features

  • Soft Foam Pack: Equipped with a hard base and footplate for stability.
  • Velcro Straps: Securely fasten the splint, providing support and immobilisation.
  • Two Sizes: Short and long box splints cater to different fracture locations.

Application Techniques

Choosing the Right Size

  • Short box splints for fractures below the knee.
  • Long box splints for fractures below the knee, feet, and toes.

Fitting the Splint

  • Ensure the splint is positioned below the knee to avoid additional weight and discomfort.
  • For ankle injuries, utilise the small box splint for immobilisation.

Proper Application

  • Support the fracture to minimize pain and further complications.
  • Slide the splint underneath the leg with gentle lifting, avoiding excessive flexation.
  • Utilize the underside of the ankle or the back of the knee for support during movement.

Securing the Splint

  • Fasten the Velcro straps, ensuring they do not exert pressure directly over the fracture.
  • Check for any hollows or dips and use packing, such as gauze, for additional support.
  • Inspect the limb for injuries and ensure proper circulation before tightening the splint.

Final Steps

  • Once all straps are secured, cross the footplate straps over the bridge of the foot to lock everything in place.
  • Immobilize the foot, ankle, tibia, and fibula to form a solid fixed unit.


Box splints provide effective immobilisation and support for lower limb fractures, ensuring patient comfort and safety during transportation and treatment.
