  • Target disc collapse (disc height loss)
  • Active systemic or spine infection
  • Recent (< 3 months) therapeutic interventions (i.e., IDET, PRP or stem cell injections) on the target disc(s)
  • Any surgery at the index level (i.e. discectomy or intradiscal ablation) or any extensive surgery (fusion, artificial disc, laminectomy) at any lumbar level
  • Previous treatment of target disc level with steroid injection, intradiscal injection, trigger point injection, facet or medial branch block within 90 days of enrollment
  • Active malignancy
  • Spinal tumor
  • Presence of extruded disc herniation or wide annular fissures confluent with large disc protrusions at the symptomatic level.
  • Symptomatic spinal stenosis (i.e., neurogenic claudication)
  • 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

Tiltaksbeskrivelse
Tidsramme
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.
1 Month compared to Baseline
Assess occurrence of serious adverse events post-treatment.
Tidsramme: Through 1 Month post procedure

Frequency of serious adverse events post implant
Through 1 Month post procedure

Tidsramme: 3, 6, 12, and 24 months post procedure

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.

3, 6, 12, and 24 months post procedure
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
