Splint Position

Forearm Component

  • Start: palmar metacarpal heads
  • Wrap around elbow
  • End: dorsal metacarpal heads

Arm Component

  • Start: media proximal humerus
  • Wrap around elbow
  • End: lateral proximal humerus
  • Elbow at 90º
  • Forearm neutral with thumb up
  • Slightly extended wrist (10–20º)


  • Pad the hand, wrist, and humerus evenly, paying particular attention to areas of possible friction, such as the elbow where the 2 separate pieces of splinting material are overlapping
  • First apply the sugartong splint to the forearm/wrist and secure with elastic bandage.
  • Then apply the second sugartong to the upper arm. Start in the axilla, wrap under the elbow and end over the deltoid. Secure the second sugartong with elastic bandage.
