In an adult (usually elderly) patient with an osteoporotic vertebral compression fracture, what criteria dictate managing with medical therapy and rehabilitation versus referring for orthopedic surgical intervention?

Management of Osteoporotic Vertebral Compression Fractures: Rehabilitation Medicine vs Orthopedic Surgery

Most osteoporotic vertebral compression fractures should be managed with medical therapy and rehabilitation medicine, reserving orthopedic surgical referral only for patients with neurological deficits, spinal instability, or those who fail 3 months of conservative treatment with persistent severe pain. 1, 2

Initial Management Algorithm: Start with Rehabilitation Medicine When:

• Neurologically intact (no cord compression, no radiculopathy)
• Acute fracture (0-5 days from onset)
• Stable fracture pattern on imaging
• No evidence of malignancy

Begin calcitonin 200 IU for 4 weeks for acute fractures (moderate strength recommendation) 2. This provides clinically important pain reduction at 1,2,3, and 4 weeks. Simultaneously initiate:

• Pain control with acetaminophen or NSAIDs for mild pain; opioids for moderate-severe pain 3
• Short-term bed rest (minimize to prevent deconditioning)
• Bisphosphonates or denosumab for osteoporosis treatment 3
• Calcium and vitamin D supplementation
• Progressive mobilization with physical therapy
• Bracing if needed for pain control

Refer to Orthopedic Surgery When:

Absolute Indications (Immediate Referral):

• Neurological deficits present (cord compression, radiculopathy, cauda equina)
• Spinal instability on imaging
• Pathologic fracture from malignancy (requires SINS scoring system) 1
• Progressive vertebral collapse with kyphotic deformity causing pulmonary dysfunction 1

Relative Indications (Consider After Conservative Trial):

• Failure of 3 months of conservative management with persistent severe pain 1

  • The VERTOS II trial demonstrated that patients achieving pain relief with medical management typically do so by 3 months
  • Those without adequate relief by 3 months are candidates for vertebral augmentation (VA)

• Chronic intractable back pain (15-35% of patients) 4

• Severely collapsed vertebra leading to progressive kyphosis

• Chronic pseudarthrosis 4

Vertebral Augmentation Considerations:

Kyphoplasty has weak recommendation support for neurologically intact patients with symptomatic fractures who fail conservative management 2. The evidence shows:

• Vertebroplasty has a strong recommendation AGAINST routine use 2
• Kyphoplasty shows superior functional recovery compared to vertebroplasty due to better correction of spinal deformity and vertebral height restoration 1
• Both procedures are equally effective for pain reduction, but kyphoplasty has less cement leakage 1
• VA is effective for fractures <6 weeks duration, though benefit persists even for fractures >12 weeks 1

Common Pitfalls to Avoid:

1. Don't rush to vertebral augmentation - The majority of patients improve with conservative management by 3 months 1
2. Don't miss malignancy - New back pain in cancer patients requires biopsy confirmation before treatment 1
3. Don't ignore osteoporosis treatment - Secondary fracture prevention is paramount; initiate bisphosphonates or denosumab immediately 3, 5
4. Don't overlook neurological examination - Any deficit mandates immediate surgical consultation 4

Timeline for Decision-Making:

• 0-5 days: Initiate calcitonin + conservative management 2
• 3 months: Reassess - if inadequate pain relief, consider orthopedic referral for possible kyphoplasty 1
• Anytime: Immediate orthopedic referral if neurological deficits develop or instability identified

The key distinction is that rehabilitation medicine manages the stable, neurologically intact patient, while orthopedic surgery manages instability, neurological compromise, or refractory pain after 3 months of conservative treatment.
