Lumbar Decompression Relieves Spinal Stenosis Pain More Than Epidural Injection
Source— Pain Medicine News
November 1, 2019
This one-page Pain Medicine News article states that, “Minimally invasive lumbar decompression (mild®) reduced back pain caused by lumbar stenosis, and decreased opioid use, in patients far more effectively than epidural steroid injection (ESI),” according to a study. Findings from that study were presented in a research poster by sole author Navdeep Singh Jassal, MD, at the 2019 annual meeting of the American Society of Interventional Pain Physicians.
Dr. Jassal explains that although, “epidural injections are efficacious to treat acute radiculopathy, a pain that is caused by an inflammatory condition, lumbar spinal stenosis (LSS) is caused by compression of the nerve roots, and the only effective way to treat it is to decompress the spine.” Detailing the study, the article states that it “included 33 patients with a mean age of 77.9 years, who were treated with mild® between February 2018 and January 2019, at a single center. All patients had presented with moderate to severe central stenosis, including lumbar ligamentum flavum hypertrophy, as well as facet hypertrophy and degenerative disk disease, and 82% had presented with foraminal stenosis. They had failed conservative treatment, including at least one epidural steroid injection per patient.”

Treatment options shown are commonly offered once conservative therapies (e.g., physical therapy, pain medications, chiropractic) are not providing adequate relief. This is not intended to be a complete list of all treatments available. Doctors typically recommend treatments based on their safety profile, typically prioritizing low risk/less aggressive procedures before higher risk/more aggressive procedures, but will determine which treatments are appropriate for their patients.
Although the complication rate for the mild® Procedure is low, as with most surgical procedures, serious adverse events, some of which can be fatal, can occur, including heart attack, cardiac arrest (heart stops beating), stroke, and embolism (blood or fat that migrates to the lungs or heart). Other risks include infection and bleeding, spinal cord and nerve injury that can, in rare instances, cause paralysis. This procedure is not for everyone. Physicians should discuss potential risks with patients. For complete information regarding indications for use, warnings, precautions, and methods of use, please reference the devices’Instructions for Use.
Patient stories on this website reflect the results experienced by individuals who have undergone the mild® Procedure. Patients are not compensated for their testimonial. The mild® Procedure is intended to treat lumbar spinal stenosis (LSS) caused by ligamentum flavum hypertrophy. Although patients may experience relief from the procedure, individual results may vary. Individuals may have symptoms persist or evolve or other conditions that require ongoing medication or additional treatments. Please consult with your doctor to determine if this procedure is right for you.
Reimbursement, especially coding, is dynamic and changes every year. Laws and regulations involving reimbursement are also complex and change frequently. Providers are responsible for determining medical necessity and reporting the codes that accurately describe the work that is done and the products and procedures that are furnished to patients. For this reason, Vertos Medical strongly recommends that you consult with your payers, your specialty society, or the AMA CPT regarding coding, coverage and payment.
Vertos Medical cannot guarantee coding, coverage, or payment for products or procedures. View our Billing Guide.
