What is the best course of treatment for a patient with osteopenia and an acute thoracic compression fracture?

Management of Osteopenia with Acute Thoracic Compression Fracture

Begin with medical management for the first 3 months, including calcitonin for acute pain relief, calcium and vitamin D supplementation, early mobilization, and immediate initiation of osteoporosis pharmacotherapy—only consider vertebral augmentation if conservative treatment fails after 3 months. 1, 2, 3

Initial Pain Management (First 4 Weeks)

• Start calcitonin immediately for acute pain relief in the first 4 weeks after fracture identification, as it provides clinically important pain reduction beyond standard analgesics 4, 2, 3
• Use NSAIDs or opioids as needed for pain control, though exercise caution with opioids due to sedation, nausea, decreased physical conditioning, and increased fall risk—particularly problematic in elderly osteoporotic patients 3

Conservative Management Strategy

• Avoid prolonged bed rest or immobilization—this causes rapid bone loss and muscle weakness, creating a vicious cycle of deconditioning and increased fracture risk 4, 3
• Most osteoporotic compression fractures resolve spontaneously within 6-8 weeks (natural history shows gradual improvement in pain over 2-12 weeks) 1, 3
• Implement physical therapy focusing on maintaining mobility, strengthening core and back muscles, and improving posture 4

Essential Supplementation

• Prescribe at least 1000 mg elemental calcium daily 1, 3
• Prescribe at least 800 IU vitamin D daily 1, 3

Immediate Osteoporosis Pharmacotherapy

This is critical and should not be delayed—patients with osteopenia who sustain a compression fracture have a 20% risk of another vertebral fracture within 12 months 3

• Consider bisphosphonates (ibandronate or generic oral bisphosphonates) for preventing additional symptomatic fractures 3
• For postmenopausal women with osteopenia and a history of osteoporotic fracture, denosumab (Prolia 60 mg subcutaneously every 6 months) is FDA-approved and reduces the incidence of vertebral, nonvertebral, and hip fractures 5
• Important caveat: If the patient has advanced chronic kidney disease (eGFR < 30 mL/min/1.73 m²), denosumab carries a black box warning for severe hypocalcemia and requires evaluation for CKD-MBD prior to initiation 5

When to Escalate Care

Immediate Referral to Orthopedic Surgery or Neurosurgery:

• Neurological deficits 2
• Evidence of spinal instability 2
• Significant spinal deformity or progressive kyphosis 2

Consider Vertebral Augmentation After 3 Months:

• Persistent severe pain despite conservative management for 3 months 1, 2, 3
• Worsening symptoms despite medications 1
• Spinal deformity or pulmonary dysfunction 1, 2
• Contraindication to pain medications or requirement for parenteral narcotics 3

Evidence note: The American College of Radiology supports vertebral augmentation based on studies showing benefits in pain intensity, vertebral height, sagittal alignment, functional capacity, and quality of life compared to conservative management, though the American Academy of Orthopaedic Surgeons recommends against vertebroplasty based on two studies showing no difference compared to sham procedures 3

Critical Pitfalls to Avoid

• Do not delay osteoporosis pharmacotherapy—the 20% risk of another vertebral fracture within 12 months makes this urgent 3
• Do not assume all pain is from the acute fracture—obtain MRI if symptoms change or imaging is >3 months old to identify new fractures 3
• Do not overlook the diagnosis—thoracic compression fractures in osteopenia are frequently missed in minor trauma cases, especially at the thoracolumbar junction (T12-L1) 6
• Recognize high-risk features: Patients with osteopenia who sustain compression fractures, especially those >60 years old or with fractures at the thoracolumbar junction, are at higher risk for progressive compression and kyphosis and require closer follow-up 7

Follow-Up Protocol

• Reassess at 4-6 weeks to evaluate response to initial treatment 2
• If symptoms persist beyond 8 weeks, obtain additional imaging to rule out fracture progression or new fractures 2
• Consider referral to interventional radiology or pain management if pain persists after 3 months of conservative management 2
