Why Splinting Matters
On a ranch, broken bones, sprains, and dislocations can happen far from medical care. Proper splinting immobilizes the injury, reduces pain, prevents further damage, and makes transport safer. While splinting won't fix the injury, it protects the injured area until professional medical care is available - which in rural areas may be a significant time.

When to Splint
Indications for Splinting
- Bone visible through skin (open fracture - cover wound, then splint)
- Crepitus (grinding feeling or sound)
- Inability to use the limb
- Swelling
- Bruising
- Tenderness to touch
- Pain with movement
- Mechanism of injury suggests fracture
- Severe sprains
- Any injury where immobilization reduces pain
The General Rule

Splinting Principles
The Basics
- Only exception: if circulation is compromised and you have training
- Position of comfort for the patient
- For lower leg fracture: immobilize ankle and knee
- This prevents movement at the injury site
- Use soft material between splint and bone
- Prevents additional injury from splint
- Skin color (pink = good, blue/white = problem)
- Capillary refill (press fingernail, color should return in <2 seconds)
- Sensation (can they feel touch?)
- Movement (can they wiggle fingers/toes?)
- After splinting, elevate above heart level if comfortable
- May not be possible with some injuries
Circulation Checks: CSM
- Sensation: can they feel you touching fingers/toes?
- Movement: can they wiggle fingers/toes?
Splinting by Body Part
Arm/Forearm
- Padded boards
- Magazines, newspapers
- Folded cardboard
- Apply padding
- Place splint material along forearm, including wrist and past elbow
- Secure with bandages or ties (not too tight)
- Apply sling to support arm
- Recheck CSM
Wrist/Hand
- Padded board
- Bulky dressing with outer support
- Support entire hand and wrist
- Pad between fingers if injuries there
- Secure with roller bandage
- Apply sling
Upper Arm (Humerus)
- SAM splint if available
- Padding
- Apply sling
- Secure arm to body with swathe (wrap around body)
- Pad armpit
- Check CSM
Shoulder/Collarbone
- Swathe
- Padding
- Apply sling
- Secure with swathe to body
- Pad as needed for comfort
Lower Leg (Tibia/Fibula)
- Padded boards (2, one on each side)
- Pillow
- Blanket roll
- Stabilize foot/ankle
- Apply padding
- Place splint material on both sides of leg
- Immobilize from above knee to below ankle
- Secure with bandages
- Recheck CSM
Ankle/Foot
- SAM splint
- Blanket
- Bulky padding
- Pillow wrapped around ankle/foot
- Secure with bandages
- Elevate
Upper Leg (Femur)
- Significant pain
- Requires full leg immobilization
- Blankets/padding
- Ties/bandages
- Apply padding
- Place splint from hip to below ankle (both sides if available)
- Secure at multiple points
- Pad groin and knee
- Recheck CSM
Knee
- Padded boards
- Blanket/pillow
- Place padding behind knee
- Apply splint material
- Immobilize from mid-thigh to mid-calf
- Do not try to straighten if bent
- Secure
Pelvis/Hip
- Call for professional help
- Immobilize by securing legs together
- Support in position found
- Treat for shock
Splinting Materials
Commercial Options
- Moldable to any shape
- Reusable
- Compact
- Excellent for field use
- Cost: ~$10-15
- Various sizes
- Easy to apply
- May not work well in temperature extremes
- Requires training
- For trained responders only
Improvised Materials
- Rolled newspapers or magazines
- Cardboard
- Pillows and blankets
- Sleeping pad
- Folded clothing
- The body itself (adjacent finger, other leg)
- Towels
- Blankets
- Foam
- Gauze pads
- Belts
- Strips of cloth
- Duct tape (not directly on skin)
- Rope (with padding)
Special Situations
Open Fractures
- Cover wound with sterile dressing (do not push bone back in)
- Splint as usual
- This is a surgical emergency - rapid transport needed
Suspected Spinal Injury
- Don't move patient
- Manual stabilization of head/neck
- Call for help
- Once spine is managed, assess extremities
Dislocations
- Do not try to reduce (put back in place)
- Check CSM carefully
- Ice if available
- Urgent medical attention needed
Cold Injuries with Fractures
- Do not rub or rewarm if refreezing possible
- Splint carefully with extra padding
- Keep frozen tissue elevated
After Splinting
Monitoring
- Splint security
- Patient comfort
- Signs of swelling
Documentation
- Mechanism of injury
- Time splint applied
- CSM before and after
- Any changes during transport
Transport Considerations
- Support during movement
- Avoid jostling injured area
- Continue monitoring
Common Mistakes
Splint Too Tight
Inadequate Immobilization
No Padding
Trying to Realign
Not Checking Circulation
---Practice Scenarios
Scenario 1: Wrist Injury from Fall
- Worker falls, lands on outstretched hand
- Wrist pain, swelling, deformity
- Apply SAM splint from fingers to mid-forearm
- Sling for support
- Ice, elevate, transport
Scenario 2: Lower Leg from Livestock Kick
- Kicked in shin, obvious deformity
- Immobilize with SAM splints on both sides
- Support from above knee to below ankle
- Check pulse at foot
- Call for help, treat for shock
Scenario 3: Isolated Finger Fracture
- Finger struck by gate
- Swollen, painful, won't bend
- Buddy tape to adjacent finger
- Ice, elevate
- Seek medical evaluation
Bottom Line
- Splint as you find it - Don't try to realign
- Immobilize above and below - Include joints on either side
- Pad bony prominences - Protect from pressure
- Check CSM - Before and after splinting
- When in doubt, splint - Better safe than sorry
- Use what you have - Improvise if needed
- Open fractures are emergencies - Cover, don't push back in
- Monitor continuously - Check circulation regularly
- Don't move unnecessarily - Especially with major injuries
- Get training - Practice builds competence
