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 This study
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 Results may not be published yet.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

Summary

Researchers compare three fluoroscopy-guided epidural steroid injection techniques for adults with leg pain from a herniated disc. Ninety-nine participants receive either a high-volume interlaminar injection, a low-volume interlaminar injection, or a transforaminal injection. The trial tests whether the pattern of contrast dye spreading in the epidural space predicts meaningful pain relief at three months.

What this could mean

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

Active substance
Epidural steroid injection with betamethasone and bupivacaine, given by one of three fluoroscopy-guided approaches
What this could lead to
If contrast spread predicts who responds, doctors could tailor the injection approach to each patient and avoid treatments unlikely to help.
What could go wrong
Epidural steroid injections can cause temporary soreness, headache, or, rarely, infection or nerve injury. Contrast patterns may not predict relief, and any benefit often fades within weeks to months.
