What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This trial tests whether a novel surgical technique called vertebropexy—which uses a donor ligament to stabilize the spine—can match or outperform standard decompression or fusion surgery for degenerative lumbar spinal disease. The study enrolls adults needing single- or two-level lumbar surgery for spinal stenosis with or without degenerative listhesis. Researchers will compare pain, disability, and the need for additional surgery over time.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Vertebropexy (ligamentous fixation) surgery
What this could lead to
If successful, vertebropexy could offer a less invasive alternative to spinal fusion, potentially preserving more motion and reducing the need for additional surgery.
What could go wrong
This is a relatively new technique, and it may not be as effective as fusion for stabilizing the spine. There is also a risk of graft-related complications or the need for revision surgery.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 164 people

The number the study aims to enrol. It can still change while the study runs.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Age ≥ 18 years * Single-level or two-level lumbar surgery needed * Indication for decompression surgery in patients with spinal canal stenosis and additional stable degenerative listhesis (without facet joint effusion ≥ 2mm) * Indication for fusion surgery in patients with spinal canal stenosis and additional unstable degenerative listhesis (facet joint effusion ≥ 2mm), in patients with foraminal stenosis and additional degenerative listhesis, and in patients with segment degeneration of the disc * Understanding in German language Exclusion criteria: * Indication for decompression and/or fusion surgery in patients with solely disc herniation, fractures, lytic listhesis, tumor * Patients undergoing revision surgery for infection * Patients undergoing revision surgery on the same level if bony structures have been removed (e.g. prior laminectomy or midline decompression) * Patients undergoing revision surgery in case of prior fusion surgery * Inability to understand the study for linguistic or cognitive reasons * Anticipated clinical follow-up of less than 6 weeks after inclusion * Participation in other clinical trials
