What symptoms and clinical features indicate candidacy for basivertebral nerve ablation (BVNA) in a patient with persistent axial low‑back pain after an osteoporotic vertebral compression fracture?

Symptoms Indicating Candidacy for BVNA

Patients are candidates for basivertebral nerve ablation when they present with chronic axial (midline) low back pain lasting ≥6 months that worsens with sitting, forward flexion, bending, and lifting, improves with standing or walking, and demonstrates Modic type 1 or type 2 endplate changes on MRI after failing conservative management. 1, 2

Core Clinical Features

Pain Characteristics

• Axial (midline) low back pain - not radicular or leg-dominant pain 2
• Mechanical pattern: worse with sitting, forward flexion, bending, lifting, and driving 3
• Relief pattern: improves with standing, walking, or lying down 3
• Duration: minimum 6 months of persistent symptoms 1, 4

Essential Imaging Findings

• Modic type 1 changes (bone marrow edema on MRI - hyperintense on T2, hypointense on T1) OR
• Modic type 2 changes (fatty marrow replacement - hyperintense on both T1 and T2) 5, 1, 2
• Changes must be present at the vertebral endplates corresponding to the pain location 3

Treatment Failure Requirements

Patients must have failed conservative management before BVNA consideration 1. This includes:

• Nonsteroidal anti-inflammatory drugs
• Physical therapy
• Activity modification
• Other interventional procedures (epidural injections, facet interventions, medial branch blocks) 3

The 2025 BMJ guideline 6 strongly recommends against epidural injections and radiofrequency ablation for chronic axial spine pain, which reinforces that patients failing these traditional interventions may benefit from BVNA as a distinct treatment targeting a different pain generator.

Expanding Indications

Recent evidence 5, 7, 3 demonstrates BVNA efficacy beyond original trial criteria:

• Post-fusion patients with persistent vertebrogenic pain at adjacent or fused levels 3
• Advanced osteopenia (T-score -2.2) without fracture 7
• Multilevel Modic changes 4

Critical Exclusion Criteria

• Active vertebral compression fracture - this is the key distinction from your clinical scenario
• Neurologic deficits requiring surgical decompression
• Active spinal infection
• Uncorrectable coagulopathy 1

Important Clinical Distinction

BVNA addresses vertebrogenic pain from endplate degeneration, NOT acute fracture pain. The evidence provided focuses on vertebral augmentation (vertebroplasty/kyphoplasty) for osteoporotic compression fractures 8, 9, 8, which is a completely different indication and procedure than BVNA.

For a patient with persistent axial pain AFTER an osteoporotic vertebral compression fracture has healed, BVNA candidacy would require:

1. Fracture healing confirmed on imaging (typically 3+ months post-fracture) 8
2. Persistent midline mechanical back pain despite fracture healing
3. Development or persistence of Modic changes at the affected or adjacent levels
4. Pain pattern consistent with vertebrogenic pain (mechanical, axial, worse with flexion)
5. Failure of conservative management including any vertebral augmentation if performed

The case report of BVNA in advanced osteopenia 7 demonstrates safety in metabolic bone disease when no acute fracture is present, suggesting potential applicability in post-fracture scenarios once healing is complete and vertebrogenic pain persists.
