About this study

The zLOCK Facet Stabilization System is a fixation device intended to provide posterior stability in the lumbar spine fusion procedure. The system can be placed either as an adjunct to an inter-vertebral anterior cage or as stand-alone with/ without additional decompression of the dural sac or nerve roots as appropriate for the specific patient and surgeon's discretion. The zLOCK implant is placed inside the facet to stabilize the motion and enhance the bony fusion of the joint. The zLOCK Facet Stabilization System is intended for single-level stabilization of a spinal motion segment in order to promote bony fusion of the joint. The zLOCK system is indicated for use from L1-L2 to L5-S1 joints.

The zLOCK implant is inserted into the facet joint space while adapting to the joint's changing geometry. Stabilization is achieved by a firm grip of each joint bone and resisting any relative motion. The zLOCK implant is placed percutaneously and requires only one incision per side, thereby reducing the invasiveness procedure duration and shortening the recovery period.

This pivotal study was designed in order to assess the safety and effectiveness of the zLOCK system.

What is being measured

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

  1. Incidence of Treatment-Emergent Adverse Events as assessed by paucity of device related reoperation

    The safety of the zLOCK Facet Implant System will be established based on the paucity of device-related reoperations.

    Measured: 3 months

Secondary outcomes (1)
  1. Change in pain level measured by Visual Analog Score for pain

    The efficacy assessment of the ZygoFix Facet stabilization System will be established by change in pain level

Questions about this trial

What is this clinical trial studying?

A study testing zLOCK Facet Stabilization System in people with Low Back Pain, run by ZygoFix at 2 sites in 2 countries.

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 9 inclusion and 15 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: status not confirmed, as of the sponsor's last update on 7 Feb 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 Germany, Italy. 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?

Results are not available in the source record.

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

Contact Hanna Levy, Dr. (+972522824966, hanna@qsitemed.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of Treatment-Emergent Adverse Events as assessed by paucity of device related reoperation (time frame: 3 months). 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 7 Feb 2024.
