What is the appropriate evaluation and management of a cervical compression fracture in an elderly patient with suspected osteoporosis?

Cervical Compression Fracture: Evaluation and Management

Immediate Imaging and Assessment

In elderly patients with suspected cervical compression fractures, CT of the cervical spine is the gold standard for fracture detection and should be performed immediately, as radiographs miss approximately two-thirds of fractures visible on CT. 1

• CT cervical spine is significantly more sensitive than plain radiographs for identifying cervical spine fractures, with radiographs depicting only about one-third of fractures visible on CT 1
• All elderly patients ≥65 years with blunt trauma should be considered for cervical spine imaging even with low-risk clinical criteria, as NEXUS criteria sensitivity declines to only 66-89% in this age group 1
• MRI of the cervical spine without contrast should be obtained after CT to identify bone marrow edema (indicating fracture acuity), assess for spinal cord compression, detect retropulsed bone fragments, and exclude pathologic causes 2
• Perform a complete neurological examination documenting motor strength, sensory deficits, reflexes, and bowel/bladder function 2, 3

Critical Red Flags Requiring Immediate Surgical Consultation

Any neurologic deficit mandates urgent surgical decompression and stabilization after initiating corticosteroid therapy—do not delay transfer. 2, 4

• New motor weakness, sensory loss, or bowel/bladder dysfunction indicates spinal cord or nerve root compromise requiring emergency surgical intervention 2, 4
• Frank spinal instability with retropulsion of bone fragments into the spinal canal requires immediate surgical referral 2, 4
• Imaging evidence of spinal cord compression, especially from osseous retropulsion, triggers prompt surgical consultation 2, 4
• Inability to bear weight, focal step-off deformity, or vertebral body height loss >20% suggests instability requiring surgical evaluation 2

Conservative Management for Neurologically Intact Patients

For neurologically intact elderly patients with osteoporotic cervical compression fractures, conservative management should be the first-line approach for 3 weeks to 3 months before considering vertebral augmentation. 2, 3

Pain Management Protocol

• Start acetaminophen as first-line analgesia; avoid NSAIDs if cardiovascular or renal comorbidities exist 2
• Consider calcitonin 200 IU (nasal or subcutaneous) for 4 weeks in acute fractures, as it provides clinically important pain reduction at 1,2,3, and 4 weeks 2, 3
• Reserve short-term opioids only for severe pain, as prolonged use causes sedation, falls, decreased physical conditioning, and does not prevent the 40% failure rate of conservative management at 1 year 2

Activity Modification

• Avoid prolonged bed rest beyond acute pain control, as it leads to approximately 1% bone loss per week, rapid deconditioning, and increased fall risk 2, 4
• Encourage limited activity within pain tolerance to prevent deep-vein thrombosis and cardiopulmonary deconditioning 2

Evaluation for Pathologic Fractures

In elderly patients with cervical compression fractures, actively exclude malignancy if red-flag symptoms are present: unexplained weight loss, night pain, constitutional symptoms, or known cancer history. 2, 4

• MRI of the entire spine with and without IV contrast should be obtained if malignancy is suspected to assess epidural tumor extension and spinal cord compression 2
• Image-guided biopsy is recommended when imaging findings are ambiguous 2
• Management of pathologic fractures requires a multidisciplinary team including interventional radiology, spine surgery, and radiation oncology 2

Osteoporosis Management

All patients with cervical compression fractures require immediate initiation of osteoporosis treatment, as approximately 1 in 5 develop chronic back pain and the risk of subsequent fractures is high. 2

• Initiate oral bisphosphonates (alendronate or risedronate) immediately as first-line therapy 2
• For patients with oral intolerance, cognitive impairment, malabsorption, or poor adherence, use intravenous zoledronic acid or subcutaneous denosumab 2
• Provide calcium (1,000-1,200 mg/day) and vitamin D (≈800 IU/day) supplementation 2
• Refer to endocrinology or rheumatology within 4-6 weeks for long-term management 3, 4

Indications for Vertebral Augmentation

Vertebral augmentation should be considered for persistent severe pain after 3 weeks to 3 months of conservative management, vertebral body height loss >20%, or development of pulmonary dysfunction from kyphotic deformity. 2

• Randomized data show that 40% of conservatively managed patients fail to achieve meaningful pain relief after 1 year, supporting augmentation when conservative measures fail 2
• Kyphoplasty provides greater vertebral height restoration, better deformity correction, and lower cement-leakage rates than vertebroplasty 2
• Benefits persist even for fractures older than 12 weeks; fracture age does not independently diminish outcomes 2
• Need for parenteral narcotics or intolerable oral-analgesic side effects suggests the need for procedural intervention 2

Follow-Up Timeline

• Re-evaluate pain and functional status between 3 weeks and 3 months to decide whether escalation to vertebral augmentation is warranted 2
• Reassess at 4-6 weeks to evaluate response to initial treatment and confirm osteoporosis therapy has been initiated 3, 4
• If symptoms persist beyond 8 weeks, obtain repeat imaging to assess for fracture progression or new fractures 3, 4

Critical Pitfalls to Avoid

• Cervical compression fractures in the elderly are associated with high morbidity and mortality, even from low-level trauma—never underestimate their severity 5
• Missing neurological deficits on initial examination can lead to permanent neurological damage; always perform a thorough neurological assessment including rectal tone if indicated 2, 4
• Delaying osteoporosis evaluation is a critical error, as compression fractures are often the first presentation of severe osteoporosis requiring immediate treatment 3, 4
• Prolonged immobilization increases fall risk and paradoxically raises the likelihood of subsequent vertebral fractures 2
