What is the recommended conservative (non‑surgical) management for an adult with an acute thoracic or lumbar vertebral compression fracture and no neurologic deficit?

Conservative Management of Thoracolumbar Compression Fractures

Direct Recommendation

For neurologically intact patients with thoracolumbar compression or burst fractures and an intact posterior ligamentous complex, early mobilization without mandatory bracing is the evidence-based first-line treatment, as external orthoses provide no additional benefit in pain, disability, or radiographic healing. 1

Patient Selection for Conservative Management

Inclusion Criteria (Safe for Non-operative Treatment)

• Neurologically intact patients with no motor or sensory deficits are appropriate candidates for conservative management 2, 1
• Intact posterior ligamentous complex confirmed on imaging is essential for stability 2, 1
• AO Type A3 burst fractures without posterior column injury qualify for non-operative treatment 1
• Vertebral body collapse less than 50% of original height indicates relative stability 2

Absolute Contraindications (Require Surgical Evaluation)

• Any neurological deficit mandates surgical consultation 2, 1
• Vertebral body collapse exceeding 50% signals true instability requiring surgery 2
• Significant angulation, canal compromise, or TLICS score >4 necessitates operative intervention 1
• Evidence of shear, rotational, or translational injury components requires surgical assessment 1

Conservative Treatment Protocol

Early Mobilization Approach (Preferred)

• Initiate ambulation as soon as tolerated after injury without any brace, as Level I randomized controlled trial evidence demonstrates equivalent functional outcomes at ≥6 months compared to braced patients 1
• This approach is supported by Congress of Neurological Surgeons Grade B recommendation based on high-quality RCT data showing no difference in pain (VAS), disability (Roland-Morris), or quality of life (SF-36) between braced and non-braced cohorts 1
• Early mobilization without bracing avoids trunk muscle atrophy and learned non-use that occurs with prolonged orthosis wear 1

Optional Bracing (For Patient Comfort Only)

• When a brace is selected for short-term pain control or patient comfort, it provides no objective benefit in healing or long-term outcomes 1, 3
• Limit continuous brace use to ≤8 weeks maximum to prevent trunk muscle atrophy and functional decline 1
• The decision to use a brace is at physician discretion, recognizing it offers only subjective comfort without altering fracture healing 2, 1

Follow-up and Monitoring

Outpatient Surveillance

• Schedule prompt spine surgeon follow-up within 1-2 weeks of initial injury 2
• Obtain serial imaging to monitor for progressive deformity or delayed instability 2, 4
• CT with multiplanar reconstructions is the preferred modality for assessing fracture healing 4

Warning Signs Requiring Immediate Return

• New onset or worsening neurological symptoms (numbness, weakness, bowel/bladder dysfunction) 2
• Severe uncontrolled pain despite appropriate analgesia 2
• Inability to mobilize safely or progressive functional decline 2

Evidence Quality and Nuances

Strength of Conservative Management Evidence

The Congress of Neurological Surgeons provides Grade B recommendations based on Level I RCT evidence demonstrating that braced and non-braced management produce equivalent outcomes in neurologically intact patients with intact posterior elements 1. This represents the highest quality evidence available and directly contradicts older retrospective data from 1984 suggesting surgical superiority 5.

Conflicting Historical Data

One 1984 retrospective study suggested prophylactic surgical stabilization had advantages over conservative management, with 17% of non-operative patients developing neurologic problems and 25% unable to return to full-time work 5. However, this older evidence is superseded by modern Level I RCT data and current guideline recommendations that show equivalent outcomes 1, 6. The 2006 Cochrane review found no statistically significant difference in functional outcomes between operative and non-operative treatment, though it noted the included trial had small sample size 6.

Common Pitfalls to Avoid

• Assuming all burst fractures require surgical intervention is incorrect, as neurologically intact patients with intact posterior elements achieve equivalent outcomes with conservative care 2
• Prolonging rigid bracing beyond 8 weeks continuously leads to trunk muscle weakening and potentially worsens functional outcomes 1
• Failing to provide adequate patient education about neurological warning signs that should prompt immediate medical attention is a critical error 2
• Overlooking the importance of close follow-up to monitor for delayed instability or progression is a common mistake 2

Practical Implementation Algorithm

1. Confirm neurological status: Perform thorough motor, sensory, and reflex examination 2
2. Assess posterior ligamentous complex integrity: Use MRI or CT to evaluate for posterior column injury 1
3. Measure vertebral collapse: Calculate percentage of anterior column height loss 2
4. If all stability criteria met (neurologically intact, intact posterior elements, <50% collapse): Initiate early mobilization without brace 1
5. If patient requests brace for comfort: Prescribe thoracolumbosacral orthosis for ≤8 weeks only 1
6. Schedule 1-2 week follow-up with spine surgeon and serial imaging 2
7. Educate on red flags: New neurological symptoms, severe pain, or inability to mobilize safely 2
