The purpose of this study was to provide Level-1 objective, real-world outcome data for patients with lumbar spinal stenosis (LSS) suffering from neurogenic claudication secondary to hypertrophic ligamentum flavum (HLF). In the study, patients were treated with mild® plus conventional medical management (CMM) or CMM alone, reflecting real-world treatment progression and patient care.
Both the mild®+CMM and the control group were allowed unrestricted access to conventional real-world therapies. Patient reported outcomes included Oswestry Disability Index (ODI), Zurich Claudication Questionnaire (ZCQ), and Numeric Pain Rating Scale (NPRS). A validated Walking Tolerance Test, incidence of subsequent lumbar spine interventions, and occurrence of adverse events were used to measure objective outcomes.
Sixty-nine patients in each group were analyzed at 1-year follow-up. No device or procedure-related adverse events were reported in either group. The 1-year results of the Level-1 MOTION randomized controlled trial demonstrate the superiority of the mild® Procedure in combination with CMM over the use of CMM alone for LSS patients suffering from neurogenic claudication secondary to HLF.
Additional 1-year data for patients receiving the mild® Procedure plus CMM vs CMM alone include:
16-point mean change ODI improvement
250% improvement in walking time compared to baseline prior to the procedure
0% device- or procedure-related adverse or serious adverse events
Less than 8% of mild® patients required a subsequent intervention
Hear interventional pain specialist and national principal investigator for the MOTION Study, Dr. Timothy Deer, discuss why mild® is a safe, durable, minimally invasive procedure that has been shown to be effective as an early interventional therapy for patients suffering from symptomatic LSS.

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.
