Eligibility Criteria
Inclusion
- Are at least 18 years of age
- Have sustained a painful osteoporotic vertebral compression fracture (VCF) for at least 4 weeks but no longer than 1 year or have radiographic evidence of at least 5% worsening vertebral collapse as compared to previous radiographic evidence
- Give written Informed Consent to participate in the study and be willing to comply with protocol requirements
- Have pain requiring the regular use of analgesics or have a substantially altered life-style due to pain or disability
- Have central pain over the spinous process upon palpation at the planned level(s)
- Are appropriately communicative to verbalize and differentiate with regard to location and intensity of their pain
- Are physically and mentally willing and able to comply with the clinical and radiographic follow-up schedule

- Have an acute or persistent (not healed) fracture demonstrated by magnetic resonance imaging (MRI) or bone scan
- Have a patient self-assessment VAS score \>= 50 mm at the pre-treatment visit

- Have canal compromise causing clinical manifestations of cord, neural foramen, or nerve root compression at the level(s) to be treated
- Have a bleeding disorder, including coagulopathy
- Have severe cardiopulmonary deficiencies
- Have an active systemic or local infection
- Are currently being treated for cancer or HIV
