About this trial

This is an interventional treatment trial for Spinal Fusion focused on measuring Dorsal Root Ganglion, Neurostimulation, Failed Back Surgery Syndrome

Eligibility Criteria

21 Years - 80 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria: Indicated for a single level or two level adjacent spinal fusion having back pain and radiculopathy Have been diagnosed with chronic, intractable pain of the lower back and/or leg refractory to conservative therapy for at least 3 of months At least 6 months since last surgical procedure on the spine Be 21 years of age or older at the time of enrollment Be willing and capable of giving informed consent Be willing and able to comply with study-related requirements Exclusion Criteria: Any prior spinal fusion at index or adjacent level Pregnant Have a life expectancy of less than 1 year Be concomitantly participating in another clinical study Be involved in an injury claim under current litigation Baseline narcotic use of ≥ 100 MME per day Significant untreated addiction to dependency producing medications Current active implantable medical device Cancer Have osteoporosis Active infection Allergies to system components AGE > 80 Expected need to undergo MRI imaging in the future Other significant comorbidities

Arm Description

Outcomes

Primary Outcome Measures

Primary Safety Endpoint: Characterization of device-related adverse events
Primary Effectiveness Endpoint: Change in back and leg pain Visual Analog Score (VAS) scores
VAS scores range from 0 (no pain) to 100 (pain is as bad as it could possibly be). Decreases in scores indicate reductions in pain.

Secondary Outcome Measures

Change in neurological status
Change in neurological status measured by the neurological component of the standard physical exam.
Change in disability measured by the Oswestry Disability Index (ODI).
Each question is scored from 0-5. The scores from each question are summed, then divided by the maximum number possible, then multiplied by 100 to represent a percentage. The percentages are broken down into 5 category ranges: 0% to 20%: minimal disability, 21%-40%: moderate disability; 41%-60%: severe disability; 61%-80%: crippled; 80%-100%: bed-bound or exagerating.
Change in quality of life as measured by PROMIS Scale v1.2 - Global Health.
The is a 10-item patient-reported questionnaire in which the response options are presented as a 5-point rating scale. The results of the scores are are used to calculate two summary scores: a Global Physical Health score and a Global Mental Health score. These scores are then standardized to the general population, using the "T-Score." The average "T-Score" for the United States population is 50 points, with a standard deviation of 10 points. Higher scores indicate a healthier patient.
Change in quality of life as measured by EQ-5D-5L.
The EQ-5D-5L survey consists of 5 dimensions with the score for each ranging from 1 (no problems) to 5 (unable to do). For individual dimensions, negative changes (e.g. from 5 to 3) indicate improvement. The scores on these five dimensions will be presented as a health profile and converted to a single summary index number (utility). Positive changes in the total score indicate improvement.
Change in use of analgesics over time
Change in use of medications at all follow up visits.

Intervention Type
Device
Intervention Name(s)
DRG Neurostimulation with Spinal Fusion
Intervention Description
Surgeons will implant a neurostimulator during the same open back procedure as fusion devices (spinal fusion hardware and interbody cage) and begin neurostimulation in a short time following surgery (24 hours).
Primary Outcome Measure Information:
Title
Primary Safety Endpoint: Characterization of device-related adverse events
Time Frame
Surgery through 12 months post-op
Title
Primary Effectiveness Endpoint: Change in back and leg pain Visual Analog Score (VAS) scores
Description
VAS scores range from 0 (no pain) to 100 (pain is as bad as it could possibly be). Decreases in scores indicate reductions in pain.
Time Frame
Baseline to 3 months post-op
Secondary Outcome Measure Information:
Title
Change in neurological status
Description
Change in neurological status measured by the neurological component of the standard physical exam.
Time Frame
Baseline to 3, 6, and 12 months post-op
