The trigger finger, also known as the index finger, needs immediate immobilization upon severe injuries such as a broken or fractured bone. Continued movement can worsen damage and increase recovery time. A homemade splint secures the entire length of the finger and provides stability until a doctor diagnoses the injury. Construct homemade index finger splints with everyday household items. Careful splint construction and immediate professional medical treatment will have you on a quick road to recovery.

Things You'll Need

  • Fabric strips
  • Popsicle sticks
  • Tape

Place a popsicle stick on the underside of the injured index finger. The stick must run across the entire length of the finger. If your index finger has bone slightly protruding from the sides, the popsicle stick must be applied to the side of the finger.

Place another popsicle stick on the top side of the finger. The two popsicle sticks should be parallel to each other. Again, if you have a side protrusion, place the other stick on the opposite side of the index finger. In both scenarios, the sticks must be parallel to each other.

Firmly wrap the index finger and the popsicle stick with tape. Apply moderate pressure. Excessive pressure cuts off circulation and increases the potential of further damage. Ensure the sticks are firmly in place.

Tape the injured index finger to the middle finger on the same hand. Taping two fingers together provides added stability to the splint.

Wrap both fingers with with strips of fabric or, if available, medical gauze. The extra layer of fabric cushions the finger and prevents dirt from entering the injury. Minimize hand movement and seek immediate medical treatment. Broken and fractured fingers need professional aid to prevent the bone from healing improperly.

Tips & Warnings

  • Elevate the injured hand to reduce swelling.
