Outcome Measures

Primary Outcomes (1)

  • Percentage of Participants With a 2-point Improvement in Visual Analogue Scale

    The primary endpoint for evaluating effectiveness will be the proportion of subjects in each group achieving at least a 2-point improvement from baseline in the Visual Analog Scale.

    16 weeks

Study Arms (2)

Percutaneous Lumbar Decompression

ACTIVE COMPARATOR

Patients receiving percutaneous decompression using the mild® Device Kit.

Procedure: Percutaneous Lumbar Decompression

Lumbar Epidural Steroid Injection

ACTIVE COMPARATOR

Injection of epidural steroids into the lumbar spine

Drug: Epidural Steroid Injection

Interventions

The percutaneous procedure is performed under fluoroscopic guidance to effect a lumbar decompression with minimal surrounding tissue and bone disruption. The mild® Device Kit is utilized to access, capture and remove bone and tissue.

Also known as: mild procedure, mild lumbar decompression
Percutaneous Lumbar Decompression

Injection of epidural steroids into the lumbar spine

Also known as: ESI
Lumbar Epidural Steroid Injection

Eligibility Criteria

Age50 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Lumbar spinal stenosis (LSS) with neurogenic claudication where the Visual Analog Scale (VAS) of back and leg pain average is ≥ 5.
  • Prior failure of conservative therapy.
  • Oswestry Disability Index (ODI) score of ≥ 31%.
  • Radiologic evidence of LSS, with unilateral or bilateral ligamentum flavum ≥ 4.1mm confirmed by pre-op MRI performed within 6-12 months of baseline visit.
  • Able to walk ≥ 10 feet before being limited by pain.
  • Available to complete 24-months of follow-up.
  • Adults ≥ 50 years of age.

You may not qualify if:

  • Prior surgery at intended treatment level.
  • History of spinal fractures with current related pain symptoms.
  • Motor deficit or disabling back and/or leg pain from causes other than LSS neurogenic claudication (e.g. acute compression fracture, metabolic neuropathy, vascular claudication symptoms, etc.).
  • Significant/symptomatic disc protrusion or osteophyte formation judged by the Investigator as possible confounding factor to study results.
  • Excessive facet hypertrophy judged by the Investigator as possible confounding factor to study results.
  • Significant symptomatic foraminal stenosis.
  • Confirmed anterior or retro-listhesis ≥ 3mm.
  • Bleeding disorders and/or current use of anti-coagulants with the inability to withhold anticoagulants for required time prior to procedure.
  • Able to walk ≥ 200 yards unaided in erect non-flexed position before being limited by pain.
  • Able to stand ≥ 15 minutes in erect, non-flexed position before being limited by pain.
  • Use of acetylsalicylic acid (ASA) and/or non-steroidal anti-inflammatory drug (NSAID) within 7 days of treatment.
  • Pregnant and/or breastfeeding.
  • Body mass index (BMI) ≥ 32 as calculated using the patient's weight multiplied by 703 then divided by height in inches squared.
  • Epidural steroid, systemic steroid or any spine interventional procedure within prior six weeks of study procedure.
  • Dementia and/or inability to give informed consent and to understand and complete follow-up patient reported outcomes forms.
  • +5 more criteria
