Outcome Measures
Primary Outcomes (1)
Safety of Cryoneurolysis as Compared to Radiofrequency Ablation (RFA)
Safety will be assessed as the number of subjects with reported treatment-related adverse related to cryoneurolysis or RFA.
0-12 months
Secondary Outcomes (1)
Pain Intensity as Measured by 11-point Numeric Rating Scale (NRS) at 12 Month Follow up
12 months
Other Outcomes (3)
Functional Disability Index at 12 Month Follow up
0-12 months
Patients' Global Impression of Change at 12 Month Follow up
12 months
Satisfaction With Pain Management
12 months
Study Arms (2)
Cryoneurolysis
ACTIVE COMPARATORSubjects will receive iovera° cryoneurolysis to the medial branch nerves of the lumbar spine
Radiofrequency ablation
ACTIVE COMPARATORSubjects will receive RFA to the medial branch nerves of the lumbar spine
Interventions
The iovera° system consists of a reusable, portable Handpiece, along with single patient use sterile Smart Tips (i.e., cryoprobes) and disposable nitrous oxide (N2O) cartridges. The iovera° system produces the desired effect through initiation of a cooling cycle. Each cooling cycle is initiated by fully inserting the Smart Tip into the selected procedure site and activating the cryogen flow. The Smart Tip needles are made of stainless steel and have a closed tip, fully enclosing the cryogen. The "190" Smart Tip will be used in this study.
The RFA system consists of a Cosman, G4 Generator. The needles used are 20-gauge, 10cm long with a 10mm active tip manufactured by Cosman. A grounding pad, also manufactured by Cosman, is placed on the upper thigh for each procedure and connected to the G4 Generator.
Eligibility Criteria
You may qualify if:
- Male or female volunteers, at least 18 years of age at screening
- Primary complaint of axial low-back pain suggestive of unilateral or bilateral facet joint involvement (i.e., facet mediated CLBP)
- Low back pain is chronic (i.e., \> 3 months' duration)
- Low back pain score of ≥ 4 (i.e., moderate pain) on the 0 to 10 NRS or functional impairment at screening
- Successful trial of two diagnostic medial branch blocks consisting of two positive blocks with local anesthetic only (i.e., no steroids) that results in at least 50% relief of primary (index) pain for the duration of the local anesthetic used or history of a positive response to prior radiofrequency treatment (i.e., ≥ 6 months prior to enrollment)
- Failure of at least three months of conservative non-operative therapy (e.g., physical therapy, chiropractic care, spinal injections, NSAIDs or other appropriate analgesics),
- Able to provide informed consent, adhere to the study visit schedule, and complete all study assessments
You may not qualify if:
- Active workers' compensation, personal injury, Social Security disability insurance (SSDI), or other litigation/compensation related to the spine
- Serious spinal disorders (verified on magnetic resonance imaging (MRI)) that may impact outcomes, including any of the following:
- Suspected cauda equina syndrome (e.g., bowel/bladder dysfunction)
- Infection
- Tumor
- Traumatic fracture
- Systemic inflammatory spondyloarthropathy
- Lumbar radiculopathy/radiculitis (i.e., root irritation and deficit)
- Neurogenic claudication
- Prior lumbar spinal fusion surgery
- Comorbidity that, in the judgment of the Investigator, may affect the subject's ability to participate in the study including lumbar radiculopathy and neuropathic pain disorder
- Currently pregnant, nursing, or planning to become pregnant during the study
- Known contraindication to study devices, including any of the following:
- Cryoglobulinemia
- Paroxysmal cold hemoglobinuria
- +17 more criteria
