A Prospective Cohort Study of Basivertebral Nerve Ablation Using the Stryker OptaBlate BVN System for the Treatment of Vertebrogenic Low Back Pain

Stryker Instruments25 enrolled

Overview

The goal of this observational study is to evaluate patient outcomes following treatment of vertebrogenic low back pain using the Stryker OptaBlate BVN System. Patients treated in accordance with the device IFU as part of routine clinical care and who consent to participate will be followed for 12 months after the procedure to assess treatment outcomes.

Interventions

Basivertebral nerve ablationDEVICE

The basivertebral nerve ablation is a minimally invasive, image-guided procedure in which radiofrequency energy is used to ablate the basivertebral nerve within the vertebral body, interrupting pain signals associated with vertebrogenic low back pain.

Time frame: 3, 6 and 12 months post-procedure

Assessment of global patient satisfaction through completion of a brief, non-validated, rating-scale questionnaire.

Non-validated, rating-scale questionnaire to assess perceived satisfaction with the treatment received, willingness to undergo the same treatment again for a comparable outcome, and willingness to recommend the treatment to an individual with the same medical condition
