- Congenital or degenerative spondylolisthesis greater than grade 1
- Currently participating in another investigational study that could interfere with the outcome measures of this study
- Known anaphylactic reaction to contrast dye
- Opioid medication >60 MME/day within 60 days of enrollment
- If female, participants who are pregnant or are trying to become pregnant during the course of the trial (due to risks of additional radiation exposures); participants of child-bearing potential that are sexually active must use a reliable form of birth control and present a negative urine pregnancy test prior to the implant procedure
- Other protocol defined inclusion/exclusion may apply

Oswestry Disability Index (ODI)
Tidsramme: 1 Month compared to Baseline
|
Change from baseline in mean disability scores using Oswestry Disability Index (ODI) ODI is a self-reported questionnaire widely used to track changes in a patient's condition over time and evaluate the effectiveness of treatments for low back pain. The ODI consists of 10 sections, each addressing a specific aspect of daily functioning. A higher score indicates greater disability. The final score/index ranges from 0-100 scale. A score of 0-20 reflects minimal disability, 21-40 moderate disability, 41-60 severe disability, 61-80 crippled, and 81-100 bed bound. |

Assess change from baseline in mean pain scores using Visual Analog Scale (VAS)
Tidsramme: 1, 3, 5, 12, and 24 months post procedure
|
Change from baseline in mean pain scores using Visual Analog Scale (VAS) The VAS is a pain screening tool, commonly used to assess pain severity at that moment in time using a 0-100 mm scale, with zero meaning "no pain" and 100 meaning "the worst pain imaginable". |
1, 3, 5, 12, and 24 months post procedure

Evaluate change of baseline spinal instability using flexion-extension radiographic imaging
Tidsramme: Baseline, 1, 3, 5, 12, and 24 months
|
Proportion of participants with a 50% or greater reduction from baseline value in spinal instability (when baseline value is greater than or equal to 1.0), as measured by vertebral angular motion and sagittal plane translations on flexion-extension radiographs |
Baseline, 1, 3, 5, 12, and 24 months
|
|
Assess use of escalated interventions post-procedure
Tidsramme: From Baseline to 1, 3, 6, 12, and 24 months
|
Any of the following count as escalated interventions: increase pain medication use and additional interventions - i.e. injections and surgical interventions at the treatment level. |
From Baseline to 1, 3, 6, 12, and 24 months

Patient Global Impression of Change (PGIC)
Tidsramme: 1, 3, 6, 12, and 24 months post-implant
|
The Patient Global Impression of Change (PGIC) PGIC is a standardized tool designed to assess a patient's self-reported perception of improvement or worsening in their health status over time. The PGIC consists of 1 question, using a 1 to 7 scale: 1-Very Much Improved to 7-Very much Worse. |
1, 3, 6, 12, and 24 months post-implant
|
|
Patient Satisfaction
Tidsramme: 1, 3, 6, 12, and 24 months post-implant
|
Patient Satisfaction Survey is designed to assess a patient's self-reported satisfaction or dissatisfaction on a 5 point scale. 1- Very Satisfied to 5-Very Dissatisfied |
1, 3, 6, 12, and 24 months post-implant
