  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Age ≥ 50 years.
  • Radiographic confirmation of clinical symptoms of at least moderate degenerative spinal stenosis, of 1 to 3 adjacent segments in the L1-S1 region with the need for surgical decompression.

Who cannot join

  • Prior lumbar spine surgery.
  • Radiographically confirmed damage of a vertebral body (e.g., osteoporotic compression fracture or because of tumours), at any lumbar level.

About this study

This is a prospective, multicentric, comparative, randomised-controlled study to evaluate the safety and efficacy of the Facet Fixation implant.

The main objective is to evaluate the effectiveness of spinal decompression associated with FFX® implants compared to spinal decompression alone in treating lumbar spinal stenosis after 2 years of treatment.

Being tested
Decompression + FFX®, Decompression alone

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Decompression + FFX®Device

    Surgical treatment of degenerative lumbar spinal stenosis by spinal decompression associated with the use of FFX® implant

  • Decompression aloneProcedure or surgery

    Surgical treatment of degenerative lumbar spinal stenosis by spinal decompression alone

What is being measured

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

  1. Proportion of subjects with composite clinical success (CCS)

    The CCS will be considered as met if ALL of the following criteria are satisfied for a subject:

    • Back pain score (VAS) decrease by more than 20 mm (on 100-mm scale)
    • No secondary surgical intervention at the index level (excluding wound problems)
    • No non-surgical lumbar treatment of interest at any lumbar level

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

A study testing Decompression + FFX® and Decompression alone in people with Degenerative Lumbar Spinal Stenosis, run by SC Medica.

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 7 inclusion and 31 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: opening soon, as of the sponsor's last update on 30 Oct 2023. Status can change between updates, so confirm with the study contact before making plans.

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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proportion of subjects with composite clinical success (CCS) (time frame: 2 years). 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 30 Oct 2023.
