A lumbar fracture is a break in one of the bones of the lower back. These injuries can occur from trauma or weakened bone (such as osteoporosis) and range from mild compression fractures to more serious unstable injuries.
Quick Facts:
- Can result from trauma or osteoporosis
- Many fractures are stable and treated without surgery
- Some fractures can affect nerves
- Early evaluation helps determine the right treatment

WHAT IS A LUMBAR FRACTURE?
The lumbar spine consists of five vertebrae that support body weight and allow movement.
A lumbar fracture occurs when one of these bones breaks. The type of fracture depends on how the bone is affected.
Common Types of Lumbar Fractures
- Compression fractures – the front of the vertebra collapses
- Burst fractures – the bone breaks in multiple directions
- Fracture-dislocations – associated with abnormal alignment
👉 The most important question is whether the fracture is stable or unstable
IS THIS SERIOUS?
Lumbar fractures vary widely in severity.
Stable Fractures
- Often caused by osteoporosis or minor trauma
- Usually treated without surgery
- Low risk of nerve injury
Unstable Fractures
- Often caused by high-energy trauma
- May involve nerve compression
- May require surgical stabilization
👉 Determining stability and neurologic risk is critical
SYMPTOMS
Common Symptoms
- Low back pain
- Pain with movement
- Difficulty standing or walking
- Localized tenderness
More Concerning Symptoms
- Numbness or tingling
- Weakness in the legs
- Pain radiating into the legs
🚨 Emergency Symptoms
- Severe weakness
- Loss of bowel or bladder control
- Significant trauma with back pain
👉 These may indicate nerve involvement and require urgent evaluation
CAUSES & RISK FACTORS
Common Causes
- Falls
- Motor vehicle accidents
- Sports injuries
- Heavy lifting or sudden force
Osteoporosis-Related Fractures
- Occur with minimal trauma
- More common with aging
- Typically compression fractures
Risk Factors
- Osteoporosis
- Advanced age
- Prior fractures
- High-impact activities
HOW IS THIS DIAGNOSED?
A. Clinical Evaluation
- Assessment of symptoms and mechanism of injury
- Neurologic examination
- Evaluation of alignment and stability
B. Imaging
- X-rays to identify fractures
- CT scan (most important for fracture detail)
- MRI if nerve involvement or soft tissue injury is suspected
👉 Imaging helps determine stability and guide treatment
TREATMENT OPTIONS
Treatment depends on:
- Type of fracture
- Stability
- Alignment
- Presence of neurologic symptoms
A. Non-Surgical Treatment
Stable fractures are often treated with:
- Activity modification
- Pain management
- Bracing in some cases
- Gradual return to activity
👉 Many compression fractures heal over time
B. When Is Surgery Considered?
Surgery may be recommended when:
- The fracture is unstable
- There is nerve compression
- There is significant deformity
- Pain is severe and persistent
C. Surgical Options
When surgery is needed, options may include:
- Stabilization with screws and rods
- Spinal fusion
- Decompression of nerves
👉 The goal is to restore stability and protect nerve function
OUR APPROACH
At STLMISC, I focus on accurate diagnosis and appropriate treatment of lumbar fractures.
- Many fractures can be treated safely without surgery
- The key is distinguishing stable from unstable injuries
- I tailor treatment based on fracture pattern, symptoms, and patient factors
- Surgery is reserved for cases where stability or neurologic function is at risk
👉 The goal is safe healing with the least invasive effective treatment
WHAT TO EXPECT
Initial Evaluation
- Often performed in an emergency or urgent setting
- Imaging is obtained to assess the fracture
During Treatment
- Stable fractures: monitored with gradual return to activity
- Unstable fractures: may require surgical stabilization
Recovery
- Healing typically takes several weeks to months
- Follow-up imaging may be required
- Gradual return to normal activities
OUTCOMES & RISKS
Outcomes
- Many stable fractures heal well
- Surgical outcomes are generally good when indicated
- Early treatment improves outcomes
Risks of Untreated Injury
- Chronic pain
- Deformity
- Nerve compression
- Loss of function
FREQUENTLY ASKED QUESTIONS
Do all lumbar fractures need surgery?
No. Many are stable and treated without surgery.
How long does healing take?
Typically several weeks to a few months.
Can I stay active?
Activity is often limited initially, then gradually increased.
Are osteoporosis fractures different?
Yes. They are often compression fractures and usually treated conservatively.
