  Purpose
The purpose of this study is to determine safety and effectiveness, as measured by changes in pain, disability, patient satisfaction, and claudicatory symptoms, at 6 months following treatment with the Totalis™ Direct Decompression System or Sham Surgery in patients with lumbar spinal stenosis

Condition Intervention
Lumbar Spinal Stenosis Device: Totalis Device: Sham

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Prospective, Multi-center, Randomized Controlled Double-Blind Trial Evaluating the VertiFlex® Totalis™ Direct Decompression System Versus a Sham Surgical Procedure in Patients With Lumbar Spinal Stenosis

Primary Outcome Measures:
  • The proportion of patients who achieve the minimum clinically important difference (MCID) in any two of three domains of the Zurich Claudication Questionnaire (ZCQ) at 6 months and no interventions through 6 months [ Time Frame: 6 Months ]

Secondary Outcome Measures:
  • Visual Analogue Scale (VAS) [ Time Frame: 6 Months ]
    Visual Analogue Scale (VAS): Compared to baseline, an improvement (in leg and/or back pain) of 20 mm (on a 100mm scale) is considered clinically significant


Estimated Enrollment: 120
Study Start Date: May 2014
Estimated Study Completion Date: June 2018
Estimated Primary Completion Date: January 2018 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Totalis™ Direct Decompression Procedure
Totalis
Device: Totalis
Sham Comparator: Sham Surgical Procedure
Sham
Device: Sham

Detailed Description:

Subjects suffering from symptoms of neurogenic intermittent claudication secondary to a radiographically-confirmed diagnosis of central canal stenosis, with or without mild or moderate lateral recess stenosis, at one or two levels from L1 to L5 who meet all inclusion/exclusion criteria, including ≥6 months of non-operative management.

Patients included in the clinical investigation will return for follow-up visits at 1 week for safety evaluation, and at 6 weeks, 3 months, 6 months, 12 months, 18 months and 24 months post-treatment to collect data for evaluation of safety and effectiveness.
