  • Ulnar Gutter Splint

Background

  • This page reviews the ulnar gutter splint
  • Limits flexion/extension of the 4th/5th DIP, PIP, MCP, and wrist joints

Indications


Contraindications

  • Absolute contraindications
    • None
  • Relative contraindications
    • Open fractures
    • Injuries with neurovascular compromise

Procedure

Equipment

Preperation

  • Measure splint material
    • Measure from the DIP joint of the 4th and 5th digit to mid-forearm along ulnar surface
    • You will need 8-10 layers

Technique

  • Patient position
    • Metacarpophalangeal (MCP) joints of the 4th and 5th finger at 70 to 90° flexion,
    • Proximal interphalangeal (PIP) and distal interphalangeal (DIP) joints in slight flexion
    • Wrist in extension at 10 to 20°.
  • Stockinette
    • Should cover mid-forearm to the 4th and 5th fingertips
  • Web roll/ cast padding
    • Insert padding between the 4th and 5th fingers
    • Wrap padding from the MCP joint to the mid-forearm slightly beyond the area to be covered by the splint material
    • Overlap each turn by half the width of the padding
    • Smooth the padding as necessary
    • Tear any areas of excess padding to prevent areas of increased pressure on the skin.
  • Splinting material
    • Immerse splinting material in lukewarm water, squeeze out excess water
    • Apply the splint material along the ulnar side of the 5th finger, wrist, and forearm
    • Fold it in a U-shape around the dorsal and volar surfaces of the 4th and 5th fingers, hand, and wrist.
  • Fold the extra stockinette and cotton padding over the edges of the splinting material.
  • Wrap the elastic wrap over the splinting material distally to proximally
    • Overlap each revolution by half the width of the elastic wrap
  • Smooth out the splinting material
    • Use your palms rather than your fingertips to conform to the contour of the arms
  • Confirm the distal neurovascular status

Pearls and Pitfalls

  • Do not immobilize the thumb, index finger, or middle finger in the splint

Aftercare

  • Try to elevate extremity for the first few days to prevent more swelling
  • Advise patient to keep cast or splint clean and dry
  • Do not insert objects into splint/ cast
  • Monitor for complications (worsening pain, paresthesia/ numbness, color changes)
  • Seek further care if unable to control pain at home

Complications

  • Plaster burn/ thermal injury
  • Pressure sores
  • Nerve palsy
  • Vascular compromise
  • Splint dermatitis
  • Permanent joint stiffness
