Printable application guide

Measuring

Measure the Inside Leg (unbroken leg) and add 30cm/12inch (to give room for the traction)

Adjusting Splint

Adjust length to the above measurement. ensuring the Hoop is at an angle with the lateral (outside leg) higher than the medial (inside leg).

Set up

  • Apply the hoop Pad (to reduce pressure and secure to tight)
  • Apply the 4 slings (lowest should be 40cm from base)
  • Apply padding along slings
  • Creat a small padding for behind the knee

Application

  • Ensure Adequate analgesia (this hurts) – typically Opiates and entonox
    • Femoral nerve block may be helpful (however, this is variable due to the innovation of the femur and reduces the more distal the fracture)
  • Check Genitals not trapped – by the hoop
  • Apply skin traction & and bandage from ankle to thigh
  • Secure the tight Clip – remembering to put the padding under the clip and velcro round

The Knot

1. take the strings and pass one over and one under the sides of the frame.

2. secure tightly with a Reef Knot

3. pass strings down (one over and one under) around the base, bringing them back over the Reef Knot and  back around the base. This makes a pulley system.

4. Tension the pulley system and tie-off using a bow

5. Pass the tongue depressors (2 tongue depressors tapped together), twist the tongue depressors to achieve the required tension, and lock off against the side.

 

Bandage & Elevate

  • Bandage the leg to the sling using the bandage – to keep secure
  • Place a pillow or blankets under the splint to elevate the heel – To prevent pressure sores
