NCT01590004

Brief Summary

This study aims to develop a technical description of lumbar medial branch ablation using the LumbarCool system. The procedure uses cooled radiofrequency (cooled-RF) technology in treating patients with diagnosed lumbar facet joint pain.

Outcome Measures

Primary Outcomes (1)

  • Confirm acute safety of the procedure

    The primary outcome is to confirm acute safety of the procedure utilizing the neurological exam. The following outcome measures will also be used to confirm there are no safety concerns at one month and 3 months follow-up visits: * Pain intensity using the Numerical Rating Scale (NRS) * Change in medication usage * Assessment of adverse device effects, including neurological exam (light touch/pin prick, strength, straight leg test, gait, heel to toe/straight-line walking, heel to shin) (immediately post procedure, 1 month and 3 months).

    Baseline to 3 months post procedure.
