5. Visual Analog Scale (VAS) for pain of \> 4 on a scale of 0 to 10
6. Oswestry score of at least a moderate disability (21-40%)
7. No major surgery to the spine planned for at least 1 month following enrollment - Defined as a procedure the magnitude of a laminectomy or more
8. Life expectancy of \> 6 months.
9. Patient has sufficient mental capacity to comply with the protocol requirements
10. Availability for all study visits and phone calls
11. Understands the potential risks and benefits of participating in the study and is willing to provide written informed consent
12. Pathological vertebral fracture with 20-70% compression (compared to adjacent normal vertebral body)
13. Fracture age \< 6 months
14. Signal on MRI consistent with non-healed fracture
15. Female subjects must either be no longer capable of reproduction or taking acceptable measures to prevent pregnancy during the study
16. Subject must be willing and able to comply with specified follow-up evaluations

Exclusion Criteria:

1. Primary tumors other than plasmacytoma
2. Renal cell tumors
3. More than 80% compression of the vertebrae
4. Level(s) above T7 to treat
5. Fractures due osteoporosis
6. Burst fracture
7. Pedicle fracture
