Chronic Low Back Pain
Conditions
Brief summary
Objective of study is to evaluate the procedural success rate, clinical effectiveness, and heath-economic profile using the Intercept Intraosseous Nerve Ablation System in adult subjects with chronic low back pain in the post-market setting
Detailed description
This is a prospective, open-label, single-arm, single-center study. There is no randomization or blinding. Subjects will receive the Intercept System procedure to treat one or two motion segments at L3/L4, L4/L5, or L5/S1 as identified by Modic Type 1 or 2 changes.
Interventions
Radiofrequency ablation using Intracept System

Secondary
| Measure | Time frame | Description |
|---|---|---|
| Visual Analog Scale (VAS) | 3, 6, 9, and 12 months | Mean change in Visual Analog Scale (VAS) pain score from baseline to 3, 6, 9 and 12 months post-treatment. Scale is measured from 0 to 10, better to worse respectively. |
| Oswestry Disability Index (ODI) | 6, 9, and 12 months | Mean change in Oswestry Disability Index (ODI) score from baseline to 6, 9 and 12 months post-treatment. Scale is measured from 0 to 100, better to worse respectively. |
