Prospective, single arm, open label, multi-center study to evaluated the effectiveness of intraosseous basivertebral nerve radiofrequency ablation using the Intracept System.
This is a prospective, open-label, single-arm study of patients diagnosed with vertebrogenic low back pain for a minimum of 6 months with conservative care. Participants will receive the Intracept System procedure to ablate the basivertebral nerve within the vertebral body. Treatment is performed on all vertebral bodies with Modic type 1 or type 2 changes on MRI from L3-S1.

Oswestry Disability Index (ODI) - 3 Months
Change in mean Oswestry Disability Index (ODI) total score from baseline to 3 months post-treatment. ODI total score scale of 0 (no disability) to 100 (complete disability), with categories of 0-20 (minimal disability), 21-40 (moderate disability), 41-60 (severe disability), 61-80 (crippling back pain), and 81-100 (bed-bound or exaggerating). The minimally clinically important difference in ODI from baseline is considered to be a 10 points reduction from baseline.
Time frame: 3 months
Visual Analog Scale (VAS) - 3 Months
Change in the mean visual analog scale (VAS) low back pain from baseline to 3 months post treatment. VAS is a 10 point numeric scale with 0 being no pain and 10 being worst imaginable pain. The minimal clinically important difference is a 2 point reduction from baseline.
Time frame: 3 Months
ODI Responder Rate - 3-Month
Number \& percent of patients with greater than or equal to 15 point reduction in Oswestry Disability Index (ODI) from baseline to 3 months post treatment. ODI is scored on a scale of 0 (no disability) to 100 (complete disability), with categories of 0-20 (minimal disability), 21-40 (moderate disability), 41-60 (severe disability), 61-80 (crippling back pain), and 81-100 (bed-bound or exaggerating). The minimally clinically important difference for this tool is considered to be 10 points.
Time frame: 3 Months
VAS Responder Rate - 3 Month
Number and percentage of participants with a greater than or equal to 2 point reduction from baseline in visual analog scale (VAS) for low back pain at 3 months post treatment. VAS is a patient-reported 10 point numeric pain scale with 0 being no pain and 10 being worst imaginable pain. The minimal clinically important difference in VAS from baseline is a 2 point reduction.
Time frame: 3 Months

ODI -12 Months
Change in mean Oswestry Disability Index (ODI) total score from baseline to 12 months post treatment. ODI total score is on a scale of 0 (no disability) to 100 (complete disability), with categories of 0-20 (minimal disability), 21-40 (moderate disability), 41-60 (severe disability), 61-80 (crippling back pain), and 81-100 (bed-bound or exaggerating). The minimally clinically important difference for this tool is considered to be 10 point reduction in ODI.
Time frame: 12 Months
VAS - 12 Month
Change in mean visual analog scale (VAS) for low back pain score from baseline at 12 months. VAS is a patient-reported 10 point numeric pain scale with 0 being no pain and 10 being worst imaginable pain. The minimal clinically important difference in VAS from baseline is a 2 point reduction.
Time frame: 12 Months
ODI Responder Rate - 12-Month
Number and percent of patients with greater than or equal to 15 point reduction in Oswestry Disability Index (ODI) total score from baseline to 12 months post treatment. ODI total score scale of 0 (no disability) to 100 (complete disability), with categories of 0-20 (minimal disability), 21-40 (moderate disability), 41-60 (severe disability), 61-80 (crippling back pain), and 81-100 (bed-bound or exaggerating). The minimally clinically important difference for this tool is considered to be 10 points.
Time frame: 12 Months
VAS Responder Rate - 12 Months
Number and percent of participants with a reduction of greater than or equal to 2 points of the visual analog scale (VAS) at 12 months post treatment. VAS is a patient-reported 10 point numeric pain scale with 0 being no pain and 10 being worst imaginable pain. The minimal clinically important difference in VAS from baseline is a 2 point reduction in score.
Time frame: 12 Months
VAS Reduction 50% or More - 12 Month
Number and percent of participants that reported a 50% or greater reduction in Visual Analog Scale (VAS) from baseline to 12 months.
Time frame: 12 Months
