About this study
The goal of this mutlicenter quasi-randomized observational cohort study is to compare single vs double plating in patients with a midshaft clavicle fracture. The main question it aims to answer is:
- Does low profile double plating of midshaft clavicle fractures with one 2.0mm plate and a second 2.4 or 2.7 mm plate lead to a lower rate of re-intervention when compared to either single superior or single anterior plating?
Read the detailed description
Clavicle fractures account for 2% to 5% of all fractures in adults, with a majority of patients being young and active. A gold standard for the treatment of clavicle fractures has yet to be established, but single plated surgical intervention is most widely used. In recent years a smaller double plating technique has been described as a possible solution to the high removal rates associated with single plating. In (orthopaedic) surgery however, randomized controlled trials (RCTs) are recognized for their limitations. Although RCTs are considered the gold standard for testing the efficacy of new interventions, randomisation and blinding can be challenging. Simultaneously, there is an inclination for the usage of RCTs in clinical protocols, frequently based on the credo that it is the only valid method of comparing treatments. A natural experiment (NE), or quasi-experiments, in which groups are compared by nature of factors outside the control of the investigator (i.e. different surgical techniques between centres), offers a possible solution for methodological quality control. This study aims to increase the knowledge on surgical outcomes for single vs double plating in midshaft clavicle fractures following a natural experiment design.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Clavicle platingProcedure or surgery
VariAx 2.0mm + 2.4 or 2.7mm vs any other single plate
| Study group | Role | What they receive |
|---|---|---|
| Single plating technique | Choice of implant used for single plating left at descretion of treating surgeon. Receives: Procedure: Clavicle plating | |
| Double plating technique | Double plating consist of one VariAx 2.0mm plate positioned on the superior aspect of the clavicula and a second VariAx 2.4mm or 2.7 mm on the anterior side. Use of this implant will be according to the device's cleared indications of use. Receives: Procedure: Clavicle plating |

Questions about this trial
What is this clinical trial studying?
An observational study of Clavicle Fracture, run by Luzerner Kantonsspital.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 17 Oct 2022. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Frank Beeres, PhD/M.D. (0041412051914, frank.beeres@luks.ch), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of surgical re-interventions (time frame: 2 years follow-up). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05579873, which also lists 12 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Oct 2022.
