Fractures and Sprains
Bone and joint injuries: assessment and stabilization.
Types of Injuries
Fractures (Broken Bones)
| Type | Description |
|---|---|
| Closed | Bone broken but skin intact |
| Open (compound) | Bone pierces skin |
| Greenstick | Bone partially broken (common in children) |
| Comminuted | Bone shattered into pieces |
| Stress | Tiny cracks from repetitive stress |
Sprains
Ligament injury (connects bone to bone)
- Mild: Stretched
- Moderate: Partially torn
- Severe: Completely torn
Strains
Muscle or tendon injury (connects muscle to bone)
- Overstretched or torn muscle fibers
Dislocations
Joint comes out of normal position
- Very painful
- Obvious deformity
- Cannot move joint normally
Recognizing Bone/Joint Injuries
Signs and Symptoms
| Sign | What to Look For |
|---|---|
| Pain | At injury site, worse with movement |
| Swelling | Rapid onset, localized |
| Deformity | Unusual angle, shortening, bump |
| Bruising | May take time to appear |
| Inability to use | Can't bear weight or move normally |
| Crepitus | Grinding sensation or sound |
| Tenderness | Pain when touched |
Fracture vs. Sprain?
You often can't tell without X-ray. When in doubt, treat as fracture.
Suggestive of fracture:
- Heard a snap
- Obvious deformity
- Bone visible
- Severe pain even at rest
- Immediate inability to use
General Treatment: RICE
For most musculoskeletal injuries:
| Step | Action | Purpose |
|---|---|---|
| Rest | Stop using injured part | Prevent further injury |
| Ice | Apply cold pack | Reduce swelling, pain |
| Compression | Elastic bandage | Reduce swelling |
| Elevation | Raise above heart level | Reduce swelling |
Ice Application
- 20 minutes on, 20 minutes off
- Barrier between ice and skin (cloth)
- Don't apply directly to skin (frostbite risk)
- Most helpful in first 48 hours
Splinting
When to Splint
- Suspected fracture
- Dislocation
- Severe sprain
- Before moving victim
Splinting Principles
Goals:
- Immobilize injury
- Prevent further damage
- Reduce pain
- Protect for transport
Rules:
- Splint in position found (don't straighten)
- Immobilize joint above AND below fracture
- Pad bony prominences
- Check circulation before and after
- Don't apply over open wound (cover wound first)
Circulation Check
Before and after splinting, check:
- Pulse below injury
- Skin color (pink vs. pale/blue)
- Skin temperature (warm vs. cold)
- Sensation (can they feel touch?)
- Movement (can they wiggle fingers/toes?)
If circulation compromised after splinting:
- Loosen splint immediately
- Recheck
Improvised Splints
| Material | Use |
|---|---|
| Magazines/newspapers | Roll around limb |
| Boards | Rigid support |
| Pillows | Cushioned support |
| Towels | Padding and support |
| Body (self-splinting) | Tape arm to body, injured leg to good leg |
| SAM splint | Moldable commercial splint |
Specific Injuries
Arm/Forearm Fracture
- Support arm in position found
- Apply padded splint from shoulder to beyond wrist
- Include hand in comfortable position
- Secure with bandages (avoid fracture site)
- Support with sling
Wrist/Hand Fracture
- Place padding in palm (roll of gauze)
- Apply splint from forearm past fingertips
- Secure with bandages
- Support with sling
Finger Fracture
- Buddy tape: Tape injured finger to adjacent finger
- Place padding between fingers
- Check circulation
Leg Fracture
Upper leg (femur):
- Very serious, significant blood loss possible
- Immobilize entire leg and hip
- Pad between legs
- Secure both legs together
- Call 911 (needs traction splinting)
Lower leg:
- Apply padded splint from thigh to beyond foot
- Include foot in natural position
- Secure above and below fracture site
- Check circulation at foot
Ankle Fracture
- Splint in position found
- Pillow splint works well (wrap around ankle, secure)
- Elevate
- Ice if available
Knee Injury
- Immobilize in position found
- Long splints from hip to ankle
- Pad behind knee
- Don't straighten if bent
Shoulder/Collarbone
- Support arm against body
- Apply sling
- Secure arm to body with bandage (swathe)
Pelvis Fracture
Serious emergency. Internal bleeding likely
- Call 911 immediately
- Don't move unless necessary
- Treat for shock
- Place padding between legs
- Tie legs together gently (ankles, knees, thighs)
- Monitor vital signs
Skull/Spine
See chapter on head/spinal injuries (special protocols)
Open Fractures
Bone visible or protruding through skin.
Treatment:
- Call 911
- Control bleeding around wound (not on bone)
- Cover wound with sterile dressing
- Don't push bone back in
- Stabilize without pushing on bone
- Treat for shock
- Monitor
Dislocations
Do NOT attempt to relocate. This requires medical training.
Treatment:
- Immobilize in position found
- Apply ice to reduce swelling
- Support comfortably
- Transport to medical care
Common dislocations:
- Shoulder
- Finger
- Knee
- Hip
When to Seek Medical Care
Call 911 for:
- Open fracture
- Suspected spinal injury
- Suspected pelvis or hip fracture
- Femur fracture
- Signs of shock
- Loss of circulation below injury
Seek same-day care for:
- Any suspected fracture
- Dislocation
- Severe sprain
- Unable to bear weight
- Significant deformity
- Numbness or tingling
Can wait for regular appointment:
- Mild sprain with no deformity
- Minor strain
- Improving symptoms
Sprain and Strain Home Care
First 48-72 hours:
- Rest injured part
- Ice 20 minutes every 2-3 hours
- Compression with elastic bandage
- Elevate when possible
- Over-the-counter pain medication
After 72 hours:
- Gentle movement
- Heat may help
- Gradual return to activity
- Physical therapy if severe
Warning signs (seek care):
- No improvement in 3-5 days
- Worsening symptoms
- Inability to bear weight
- Significant swelling
- Numbness
Key Points
- When in doubt, treat as fracture - You can't tell without X-ray
- Don't straighten deformed limbs - Splint in position found
- Immobilize joints above and below - Prevents movement
- Check circulation - Before and after splinting
- Open fractures are emergencies - Call 911
- Don't relocate dislocations - Requires medical training
- RICE for most injuries - Rest, Ice, Compression, Elevation
- Pelvis and femur fractures are serious - Internal bleeding risk
