What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
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 This study
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 Results may not be published yet.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.

Summary

This study looks at people who received a total lumbar disc prosthesis (Baguera®L) for lower back pain or sciatica caused by disc degeneration or herniation. The goal is to see how many return to their original job five years after surgery. Unlike spinal fusion, which often limits mobility and prevents return to work, disc replacement aims to preserve motion and improve work outcomes.

What this could mean

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

Active substance
Baguera®L lumbar disc prosthesis
What this could lead to
If successful, this could show that disc replacement helps more people return to their original jobs compared to spinal fusion, preserving mobility and reducing disability.
What could go wrong
This is an observational study without a control group, so it cannot prove disc replacement is better than other surgeries. Results depend on individual factors like job type and overall health.

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

Inclusion Criteria: * Age over 18 years with symptomatic lumbar degenerative disc herniation and/or lumbar disc herniation. Exclusion Criteria: * Any patient who BEFORE the implantation of a complete lumbar disc prosthesis had undergone any other type of surgical intervention on the lumbar spine.
