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 Results may not be published yet.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.

Summary

This study is checking how well a special nail works for fixing thigh bone fractures. The nail has a coating designed to reduce infection. About 100 adults with thigh fractures will get this nail and be followed for a year to see if the bone heals properly and how well they can use their leg again.

What this could mean

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

Active substance
ZNN Bactiguard Retrograde Femoral Nail (a medical device coated with an antibacterial layer to reduce infection risk)
What this could lead to
If successful, this study could confirm that the Bactiguard-coated nail is a safe and effective option for fixing thigh fractures, potentially reducing infection rates.
What could go wrong
This is a post-market study, meaning the device is already approved. The main risk is that the coating may not significantly reduce infections or improve healing compared to standard nails.

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

Inclusion Criteria: * Patients must be 18 years or older. * Patient must have a femoral fracture (open, closed, monolateral or bilateral) requiring surgical intervention and be eligible for fixation by intramedullary nailing. Patients with delayed treatment (initial treatment by external fixation due to swelling / high energy trauma followed by definitive treatment by intramedullary nail) can also be included. * Patient has been or is scheduled to be treated with the ZNN Bactiguard System Retrograde Femoral Nail. * Patient must be able and willing to complete the protocol required follow-up. * Patient must have a signed EC approved consent. * Patients capable of understanding the surgeon's explanations and following his instructions. Exclusion Criteria: * Skeletally immature patients * A medullary canal obliterated by a previous fracture or tumor * Bone shaft having excessive bow or a deformity * Lack of bone substance or bone quality, which makes stable seating of the implant impossible * All concomitant diseases that can impair the operation, functioning or the success of the implant * Insufficient blood circulation * Infection * Patient is unwilling or unable to give consent. * Patient is a vulnerable subject (prisoner, mentally incompetent or unable to understand what participation to the study entails, alcohol/drug addiction, known to be pregnant or breast feeding). * Patient anticipated to be non-compliant and/or likely to have problems with maintaining follow-up program (e.g. patient with no fixed address, long distance, plans to move during course of study). * Not expected to survive the duration of the follow-up program
