About this study

Official title: Mid- or High-flex Rods Versus Low-flex Rods of SpineShape System IV for Treatment of Degenerative Lumbar Spine Diseases - a Prospective, Multicenter, Randomized Controlled Non-inferiority Study

The purpose of this multi-center, randomized, clinical study is to show that the treatment of degenerative lumbar spine with high- or mid-flex rods is not inferior to the treatment with low-flex rods in terms of clinical and safety-related results.

The primary aim is to compare the reduction in back pain after the treatment with high- or mid-flex rods with that after treatment with low-flex rods. Secondary, the functionality after treatment with high- or mid-flex rods will be compared to that after treatment with low-flex rods.

Read the detailed description

Dynamic stabilization systems for the lumbar spine are no novelty. The SpineShape System IV builds on the experience of previous systems and attempts to provide additional benefits primarily through three different and relatively elastic rod stiffnesses. 126 subjects with degenerative symptoms in 1 to 2 segments of the lumbar spine L1 to S1 will be recruited. The participants will be randomized in a 1:1:1 ratio to undergo implantation of either the elastic (experimental product group 1), medium (experimental product group 2) or stiff rod (comparison product group).

The aim of the study is to show that the treatment of degenerative lumbar spine with elastic or medium rod variants is not inferior to treatment with hard rods in terms of clinical and safety-related results. This is checked by completing a questionnaire before the surgical procedure and 3 months, 12 months, 24 months and 60 months after the surgical procedure.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Visual Analogue Scale (VAS) lower back pain

    self reported back pain intensity using Visual Analogue Scale system. 0 "no pain" to 10 "worst possible pain"

    Measured: 24 months post-implantation

Secondary outcomes (6)
  1. Visual Analogue Scale (VAS) leg pain

    self reported leg pain intensity using Visual Analogue Scale system. 0 "no pain" to 10 "worst possible pain"

    Measured: 3, 12, 24, 60 months post-implantation

  2. walking duration

    self reported walking duration in 5 categories (0-5 min, 6-15 min, 16-30 min, 31-60 min and >60min)

    Measured: 3, 12, 24, 60 months post-implantation

  3. medication consumption

    use of none, mild pain medication, non-steroidal anti-inflammatory drugs, opioids, and/or antidepressiva documented in patient's health records

    Measured: 3, 12, 24, 60 months post-implantation

  4. adverse events

    adverse events related to the device (e.g. screw loosening, screw breakage, torn rod, slipped rod or too short rod)

    Measured: after 3, 12, 24, 60 months post-implantation

  5. segmental mobility index level

    measuring the segmental mobility at index level to verify the preservation of the mobility. an average mobility per segment of >1° is considered a success

    Measured: 3, 12, 24, 60 months post-implantation

  6. ability to work/ activity (for retirees)

    self reported ability to work or activity (for retirees) in 5 categories (0%, 25%, 50%, 75%, 100%)

    Measured: 3, 12, 24, 60 months post-implantation

Questions about this trial

What is this clinical trial studying?

A study testing SpineShape System IV straight rod elastic, SpineShape System IV straight rod medium and SpineShape System IV straight rod stiff in people with Degenerative Lumbar Spinal Stenosis and Facet Joint Arthrosis, run by SpineSave AG at 2 sites in Switzerland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 12 inclusion and 20 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 25 Jun 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Sarah Abramovic (+41448669280, sarah.abramovic@spinesave.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Visual Analogue Scale (VAS) lower back pain (time frame: 24 months post-implantation). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Jun 2024.
