Casting without prior reduction versus closed reduction for displaced wrist (distal radius) fractures in people 65 and older

Official title: A Randomized Controlled Trial Comparing No Reduction to Closed Reduction for Distal Radius Fractures in Patients 65 Years and Older (DISCLOSE Trial): A Study Protocol

Run by Tampere University Hospital · NCT07042139 · Data updated 2026-11-12

This trial will test whether simply putting a cast on displaced wrist fractures in people 65 and older works as well as doing a closed reduction before casting by measuring wrist pain and function at 12 months.

Is this trial a fit for you?

Likely a good fit

Independent-living adults aged 65 or older with a low-energy displaced distal radius fracture meeting the trial's angulation or shortening criteria and without exclusion conditions are ideal candidates.

Probably not a fit

Patients with volar angulation, partial articular (AO/OTA 23B) fractures, open or high-energy injuries, bilateral distal radius fractures, concomitant injuries affecting wrist use, or who cannot consent are unlikely to benefit from the no-reduction approach tested here.

What this trial studies

This randomized controlled trial enrolls 532 patients aged 65 or older with low-energy displaced distal radius fractures and compares two approaches: immediate casting without attempting a closed reduction versus closed reduction under local anaesthetic followed by casting. Both groups receive a dorsal cast for five weeks, identical post-cast advice, and follow-up visits at 3 and 12 months, with the Patient-Rated Wrist Evaluation (PRWE) score at 12 months as the primary endpoint. No radiographs are taken during the casting period and an observational arm is offered for patients who decline randomization but consent to follow-up. The trial is run across multiple hospitals in Finland, Denmark, and Estonia with standardized treatment and outcome measurement protocols.

Why it matters

Potential benefit: If successful, older patients with displaced wrist fractures could avoid a reduction procedure and still achieve similar long-term pain relief and wrist function, simplifying care and reducing discomfort.

How similar studies have gone: Previous trials and observational studies in older adults have produced mixed but sometimes favorable results for non-reduction casting, so this larger randomized trial aims to provide more definitive evidence.

* Patients who are actively working in a paid position
* Volar angulation, partial articular fractures (AO/OTA 23B)
* Concomitant fracture of the ulna proximal to the base of the styloid process
