Lets Agree to Disagree on Operative vs Nonoperative Treatment for Distal Radius Fractures in the Elderly (LADON Radius)
An observational study of Radius Fracture Distal, run by Luzerner Kantonsspital.
Trial summary
The primary objective of this study is to determine if non-operative treatment of distal radius fractures in patients aged 65 and over leads to equal funtional results as operative treatment. To do so patients will be included from two "schools" in which treatment i seither predominantly operative or non-operative. Read more about this study

About this study
Official title: Lets Agree to Disagree on Operative Versus Nonoperative (LADON) Treatment for Distal Radius Fractures in the Elderly - a Prospective International Multicenter Cohort Study
The primary objective of this study is to determine if non-operative treatment of distal radius fractures in patients aged 65 and over leads to equal funtional results as operative treatment. To do so patients will be included from two "schools" in which treatment i seither predominantly operative or non-operative. There will be no study intervention as patients will be treated as per local standard of care. The study is set up as an international multicenter study. Those patients included in the study will be follow-up at 6 weeks, 12 weeks, 1 year and 2 years after treatment was initiated. Our hypothesis is, that patients treated operatively will have better function than those treated non-operatively.
Read the detailed description
This study is an international multicenter prospective observational cohort study for which patients will be identified after treatment has been initiated. Outcome data will be prospectively collected. Patients will be recruited from five hospitals in countries with a predominant preference for operative (Switzerland, "School" A) and non-operative treatment (the Netherlands, "School" B). After a treatment plan has been established, patients will be approached either during the index hospital admission or during one of their follow-up appointments in the outpatient clinic within six weeks to explain the purpose and procedures of the study. Patients will be asked to provide written informed consent. Following the identification of eligible patients, anonymous radiographs including key images of CT-scans if available and baseline characteristics (such as age, co-morbidities, activity level) as well as relevant laboratory results will be made available to the expert panel (details below) on a secure online platform. This will allow the members of the panel to reach a "clinical" decision regarding their treatment recommendation. The panel will be blinded to the actual treatment received and the origin of the case.
The expert panel will consist of three representatives from both "Schools". All panel members will be certified trauma surgeons from one of the participating hospitals. Eligible patients will be reviewed by the experts every two weeks. Patients will ultimately be included in the study if clinical equipoise is achieved, meaning the majority of experts in one "School", minimally two out of three, disagree with the received treatment in the other "School". For example, eligible patients would have received operative treatment based on the expert opinions in "School" A, however, were in fact treated non-operatively according to the treating surgeon in "School" B and vice versa. If the majority of the panel in one "School" agree with the received treatment in the other "School" the patient will be excluded. This will lead to two comparable groups for which true clinical equipoise exists. The actual treatment the patient receives, will continue as initially planned by the treating hospital.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
operative treatmentProcedure or surgery
Operative treatment can consist of open reduction and volar and/or dorsal plating or closed reduction and fixation with K-wires, external fixateur.
non-operative treatmentProcedure or surgery
Non-operative treatment will consist of immobilization in a below the elbow cast for 4-6 weeks with or without prior closed reduction.
| Study group | Role | What they receive |
|---|---|---|
| operative treatment | This group will consist of patients who underwent operative treatment for a distal radius fracture. Receives: Procedure: operative treatment | |

Questions about this trial
What is this clinical trial studying?
An observational study of Radius Fracture Distal, 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 3 inclusion and 11 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 30 Nov 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 Nicole M van Veelen, MD (041412051959, nicole.vanveelen@luks.ch), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
PRWE 12 weeks (time frame: 12 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 30 Nov 2022; AzTrials last refreshed its copy on 7 Nov 2026.
