Splint Application General Procedure

  • Assess pre-procedure neurovascular status (i.e., distal pulse, motor, and sensation) [1]
  • Measure and prepare the splinting material
    • May use contralateral extremity if easier
    • Most splints use a width slightly greater than the diameter of the limb
  • Apply stockinette (if applicable)
    • Extend 2" beyond estimated the splinting material length
  • Apply padding (if applicable)
    • Use 2–3 layers over the area to be splinted / between digits (when applicable)
    • Add an extra 2–3 layers over bony prominences
  • Apply splinting material
    • Lightly moisten the splinting material.
    • Place as appropriate to specific splint type
    • Once finished, if applicable fold the ends of stockinette back over the splinting material if there is excess
  • Apply elastic bandaging (e.g., ace wrap)
  • While still wet
    • May further mold the splint to the desired shape
    • Maintain position until splint material has hardened
  • Re-check and document repeat neurovascular status

Splint-Specific Details

  • Apply padding and splint material as shown in figure
  • Splint course:[1]
    • From mid radial forearm
    • Along radial aspect of forearm
    • To beyond DIP of index finger, with thumb free
  • Key anatomic positions[1]
    • Forearm in neutral position
    • Wrist slight extension (approximately 20°)
    • MCP flexed 50-70 degrees
