Spinal Fracture
Summary
A spinal fracture is a break in one or more vertebrae (the bones that make up the spine), which can occur from trauma (high-energy accidents, falls) or from weakened bones (osteoporosis, tumors). Think of your spine as a stack of bones protecting your spinal cord—when a vertebra breaks, it can damage the spinal cord (the bundle of nerves running through the spine), causing paralysis, numbness, or other neurological problems. Spinal fractures are serious injuries that require careful management to prevent spinal cord damage. The most common types are compression fractures (vertebra collapses, usually from osteoporosis) and burst fractures (vertebra explodes, usually from high-energy trauma). The key to management is recognizing the fracture (back pain, neurological symptoms), assessing for spinal cord injury (numbness, weakness, paralysis), immobilizing the spine (cervical collar, backboard), imaging to assess stability (X-ray, CT, MRI), and appropriate treatment (conservative for stable fractures, surgery for unstable or with neurological injury). Most stable fractures heal well with conservative treatment, but unstable fractures or those with spinal cord injury need urgent surgical intervention.
Key Facts
- Definition: Break in one or more vertebrae
- Incidence: Common (thousands of cases/year)
- Mortality: Low (<1%) unless complications (spinal cord injury)
- Peak age: Bimodal (young adults from trauma, older adults from osteoporosis)
- Critical feature: Back pain, may have neurological symptoms
- Key investigation: X-ray, CT (essential), MRI if neurological symptoms
- First-line treatment: Immobilization, assess stability, surgery if unstable or neurological injury
Clinical Pearls
"Immobilize first, ask questions later" — If you suspect a spinal fracture, immobilize the spine immediately (cervical collar, backboard). Don't move the patient until the spine is cleared.
"Assess for spinal cord injury immediately" — Check for numbness, weakness, paralysis, and bowel/bladder function immediately. Spinal cord injury is a medical emergency.
"CT is essential" — X-ray may miss fractures. CT is essential to assess the fracture pattern and stability. Don't rely on X-ray alone.
"Stability determines treatment" — Stable fractures can be managed conservatively. Unstable fractures or those with neurological injury need surgery.
Why This Matters Clinically
Spinal fractures are serious injuries that can cause permanent paralysis if not managed properly. Early recognition, proper immobilization, assessment for spinal cord injury, and appropriate treatment (surgery if unstable or neurological injury) are essential. This is a condition that emergency clinicians, orthopedic surgeons, and neurosurgeons manage, and prompt treatment can prevent permanent disability.
Incidence & Prevalence
- Overall: Common (thousands of cases/year)
- Compression fractures: Most common (especially osteoporosis)
- Burst fractures: Less common but serious
- Trend: Stable (common condition)
- Peak age: Bimodal (young adults 20-40 years trauma, older adults 60+ years osteoporosis)
Demographics
| Factor | Details |
|---|---|
| Age | Bimodal (young adults 20-40 years trauma, older adults 60+ years osteoporosis) |
| Sex | Varies by cause (trauma = male, osteoporosis = female) |
| Ethnicity | No significant variation |
| Geography | No significant variation |
| Setting | Emergency departments, trauma centers, orthopedic/neurosurgery |
Risk Factors
Non-Modifiable:
- Age (older = osteoporosis)
- Sex (female = osteoporosis)
Modifiable:
| Risk Factor | Relative Risk | Mechanism |
|---|---|---|
| High-energy trauma | 10-20x | Road traffic accidents, falls from height |
| Osteoporosis | 5-10x | Weak bones |
| Tumors | 3-5x | Weakened bone |
| Sports | 2-3x | High-energy trauma |
Common Mechanisms
| Mechanism | Frequency | Typical Patient |
|---|---|---|
| Road traffic accidents | 40-50% | Young adults, high energy |
| Falls | 30-40% | Older adults (osteoporosis), young (high falls) |
| Sports injuries | 10-15% | Young adults |
| Other | 5-10% | Various |
The Fracture Mechanism
Step 1: Force Application
- High-energy: Force applied to spine (trauma)
- Low-energy: Weakened bone fractures (osteoporosis)
- Result: Vertebra breaks
Step 2: Fracture Pattern
- Compression: Vertebra collapses (osteoporosis, low energy)
- Burst: Vertebra explodes (high energy)
- Flexion-distraction: Vertebra pulled apart (high energy)
- Result: Different fracture patterns
Step 3: Stability Assessment
- Stable: Spine can bear load, no risk of further injury
- Unstable: Spine can't bear load, risk of further injury, spinal cord damage
- Result: Determines treatment
Step 4: Spinal Cord Injury (If Present)
- Direct damage: Fracture fragments damage cord
- Compression: Swelling, bleeding compress cord
- Result: Neurological symptoms (numbness, weakness, paralysis)
Step 5: Healing or Complications
- Stable fractures: Usually heal with conservative treatment
- Unstable fractures: Need surgery
- Spinal cord injury: May be permanent
Classification by Type
| Type | Definition | Clinical Features |
|---|---|---|
| Compression | Vertebra collapses | Usually stable, low energy |
| Burst | Vertebra explodes | Usually unstable, high energy |
| Flexion-distraction | Vertebra pulled apart | Usually unstable, high energy |
| Fracture-dislocation | Vertebra displaced | Unstable, high energy |

What is a Spinal Fracture?
A spinal fracture is a break in one or more of the bones (vertebrae) that make up your spine. Think of your spine as a stack of bones protecting your spinal cord (the bundle of nerves running through your spine)—when a vertebra breaks, it can damage the spinal cord, causing numbness, weakness, or paralysis.
In simple terms: One of the bones in your spine is broken. This is serious because it can damage the nerves in your spine, but with proper treatment, most people recover well.
Why does it matter?
Spinal fractures are serious injuries that can cause permanent paralysis if not managed properly. Early recognition, proper immobilization, assessment for spinal cord injury, and appropriate treatment (surgery if unstable or neurological injury) are essential. The good news? Most stable fractures heal well with conservative treatment, and most people recover.
Think of it like this: It's like breaking a bone in your spine—it needs careful treatment to prevent damage to the nerves, but most people recover well.
How is it treated?
1. Immobilization (Immediate):
- Cervical collar: If your neck is injured, you'll wear a collar
- Backboard: You'll be kept still on a board
- Why: To prevent further injury while we assess the fracture
- Don't move: Until your doctor says it's safe
2. Assessment:
- Neurological examination: Your doctor will check for numbness, weakness, or paralysis
- Tests: You'll have X-rays and CT scans to see the fracture
- Why: To see how serious it is and if your nerves are affected
3. Treatment:
- If stable (no nerve damage): You'll wear a brace, take pain medicine, and gradually start moving again
- If unstable or nerve damage: You'll need surgery to stabilize the spine and relieve pressure on the nerves
- Why: To help the bone heal and prevent nerve damage
4. Rehabilitation:
- Physical therapy: You'll do exercises to regain strength and movement
- Occupational therapy: If needed, to help with daily activities
- Why: To help you recover and regain function
The goal: Help the bone heal, prevent nerve damage, and help you regain function.
What to expect
Recovery:
- Stable fractures: Usually heal within 6-12 weeks with a brace
- Unstable fractures: Usually need surgery, recovery takes longer
- If nerve damage: Recovery varies—some people recover partially, some don't
After Treatment:
- Brace: You'll wear a brace for several weeks (if stable)
- Pain: Should improve over time
- Activity: You'll gradually return to activities
- Follow-up: Regular follow-up to monitor healing
Recovery Time:
- Stable fractures: Usually 6-12 weeks
- Unstable fractures: Usually months
- If nerve damage: Recovery varies, may be permanent
When to seek help
Call 999 (or your emergency number) immediately if:
- You have back pain after a serious accident or fall
- You have numbness, weakness, or paralysis
- You can't control your bladder or bowels
- You feel very unwell
See your doctor if:
- You have back pain after an injury
- You have back pain and numbness or weakness
- You have concerns about your back
Remember: If you have back pain after a serious accident or fall, especially if you have numbness, weakness, or can't control your bladder or bowels, call 999 immediately. Spinal fractures are serious, but with proper treatment, most people recover well. Don't move until your doctor says it's safe.
