  • Assess distal pulse, motor, and sensation
  • Apply splinting material (e.g. Ortho-glass) as displayed
  • Wrist should remain slightly extended (10° to 20°) with 4th and 5th MCP at 50° to 90° flexion (the latter for Boxer's fracture) and DIP/PIP in slight flexion[1]
  • Place padding between 4th and 5th digits to prevent maceration
  • Reassess distal pulse, motor, and sensation
