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 Results may not be published yet.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.
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This status has not been confirmed recently, so it may be out of date.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

Researchers are studying people who have surgery for cervical radiculopathy, a condition where a pinched nerve in the neck causes arm or hand weakness. The study follows about 2,000 patients to see how many recover full strength and whether factors like how severe the weakness was or how long it lasted before surgery affect the outcome. Participants answer questions about their strength and neck-related disability at 3 and 12 months after their operation. The goal is to help doctors and patients make better decisions about when to operate and what to expect.

What this could mean

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

Active substance
cervical spine surgery (anterior disc removal and fusion, or posterior decompression)
What this could lead to
If the study clarifies how weakness severity and how long symptoms last affect recovery, doctors and patients could make better-informed choices about when to operate.
What could go wrong
This is an observational study, so it can show patterns but cannot prove that surgery causes better recovery. Results may not apply to people with different spine conditions or to those who do not have surgery.

Who is studied

The study will include consecutive patients operated for DCR and registered in NORspine form January 2012 through 2022, approximately 12.000 cases. Patients operated for cervical myelopathy will be excluded. Otherwise patients under the age of 16, those operated for fractures, tumours and primary infections, as well as those unable to give informed consent, are not included in the NORspine.
