Intraosseous Basivertebral Nerve Ablation for the Treatment of Chronic Low Back Pain

A Prospective, Open-Label, Single-Arm, Single-Center Study of Intraosseous Basivertebral Nerve Ablation for the Treatment of Chronic Low Back Pain

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

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.

Inclusion Criteria:

• Skeletally mature subjects age 25-70 years, inclusive
• Chronic lower back pain for at least six months
• Failure to respond to at least six months of non-operative conservative management
• Oswestry Disability Index (ODI) at time of evaluation of at least 30 points
• Modic changes (Type 1 or 2) in at least one vertebral endplate, at one or more levels from L3 to S1

Exclusion Criteria:

• Radicular pain by history or evidence of pain neurological deficit within the past one year.
• Previous surgery performed on the lumbar spine
• Current or history of symptomatic spinal stenosis
• Current or history of osteoporotic or tumor-related vertebral body compression fracture
• Current or history of vertebral cancer or spinal metastasis
• Current or history of spinal infection
• Metabolic bone disease
• BMI greater or equal to 40
• Any radiographic evidence of other important back pathology
• MRI evidence of Modic changes, Type 1 or 2 at greater than 3 vertebral bodies or at non-consecutive levels, or at vertebral bodies other than L3 to S1
• Any back pathology related to trauma, evidence of vertebral compression fracture or other spinal pathology that could affect assessment of response to back pain
• Subjects who are bed bound
• Demonstrates 3 or more Waddell's signs of Inorganic Behavior
• Any evidence of current systemic infection
