Improvised Forearm Splint: Sticks and Webbing
This skill teaches how to create a rigid, temporary splint for a suspected forearm fracture using common wilderness resources like straight sticks, soft padding, and tensioned webbing or cordage. The objective is to immobilize both the wrist and elbow joints, thereby preventing movement at the fracture site. A properly applied splint significantly reduces pain, minimizes potential nerve or blood vessel damage, and makes patient transport safer and more manageable until professional medical help can be reached. This is a critical first-aid response for backcountry injuries.

Key takeaways
- Reduced pain and movement at the fracture site.
- Intact circulation below the injury (warm, pink skin, strong pulse).
- Patient comfort (within reason) and ability to transport the limb without excessive jarring.
- The splint remains securely in place during gentle movement.
- Avoid: Tying the splint too tightly, leading to compromised circulation.
- Avoid: Using sticks that are too short, failing to immobilize both adjacent joints.
Intended uses
- Field Skills skill (Intermediate, ~10 min practice)
- Requires: Knife or saw (optional, for cutting sticks), Duct tape (optional, for securing padding or ties)
Climate suitability
Forested areas, trails, wilderness settings where sticks, natural padding, and cordage are available.

Required tools
- Knife or saw (optional, for cutting sticks)
- Duct tape (optional, for securing padding or ties)
Required materials
- Two straight sticks/saplings (diameter of wrist to forearm)
- Soft padding (clothing, bandages, leaves, moss)
- Rigid webbing, cordage, or strips of cloth (at least 3-4 feet)
Step-by-step
Assess the injury, checking for open wounds, severe deformities, or compromised circulation below the injury.
Why: Initial assessment guides immediate treatment and ensures no immediate life-threatening issues are overlooked.
Gather two straight, rigid sticks or saplings long enough to extend from above the elbow to below the wrist.
Why: Proper length ensures immobilization of the joints above and below the fracture, which is essential for stability.
Place ample soft padding, such as clothing or leaves, around the forearm, especially at bony prominences.
Why: Padding prevents pressure sores, distributes pressure evenly, and adds comfort for the injured individual.
Position one stick along the top (dorsal) side of the forearm and the other along the bottom (volar) side.
Why: Splinting both sides provides rigid support, preventing rotational and bending forces on the fractured bone.
Secure the sticks firmly with webbing, cordage, or strips of cloth, starting above and below the fracture site, then at the ends.
Why: Strategic placement of ties ensures the splint remains stable and prevents shifting of the fractured limb.
Verify the splint is snug enough to prevent movement but not so tight as to cut off circulation.
Why: Checking circulation confirms the splint is effective without causing further harm or tissue damage.
Create a sling to support the arm, positioning the hand higher than the elbow.
Why: A sling provides additional support, reduces swelling, and minimizes patient discomfort during transport.
Tip: Always prioritize patient comfort; a slightly less rigid splint that doesn't cause excruciating pain is often better than a perfectly rigid one that makes the patient scream.
Common mistakes
- Tying the splint too tightly, leading to compromised circulation.
- Using sticks that are too short, failing to immobilize both adjacent joints.
- Insufficient padding, causing discomfort and potential pressure points.
- Not checking for proper circulation after applying the splint.
Troubleshooting
- If circulation is compromised (numbness, tingling, cold, pallor), immediately loosen and reapply the ties.
- If the splint feels unstable, add more ties or reposition the sticks for better leverage.
- If patient pain increases after splinting, reassess for pressure points or improper alignment.
- If padding shifts, reinforce it with additional material or secure it with tape before re-tying.

Practice this skill by splinting a partner's arm, using only materials found in your immediate outdoor environment.
Indicators of success
- Reduced pain and movement at the fracture site.
- Intact circulation below the injury (warm, pink skin, strong pulse).
- Patient comfort (within reason) and ability to transport the limb without excessive jarring.
- The splint remains securely in place during gentle movement.
