Recruitment COMPLETED! -
Recruitment to The BLOCK Trial was stopped on 24 August 2026 following the planned interim analysis at approximately 50% of the target sample size. Based on the interim results, the independent Data Monitoring and Safety Committee recommended stopping recruitment, a recommendation supported by the Steering Committee.
Follow-up and final analyses are ongoing. Treatment allocation remains blinded, and no conclusions regarding the comparative effects of the intervention will be made until the final analyses are complete.
We sincerely thank all participants and participating sites for their contributions and look forward to sharing the results.

Ultrasound-Guided Nerve Blocks Improve Success Rate of Closed Reduction of Colles' Fractures.
A new notable study from Central and Northern Jutland is shedding light on how nerve blocks can help manage Colles fractures in the Emergency Department. The study investigated whether using peripheral nerve blocks (median and radial nerve blocks) during the procedure could improve the quality of the closed reduction.
Interestingly, while patients didn’t report less pain during the closed reduction procedure compared to the standard haematoma block, those who got the nerve blocks ended up with better bone alignment on X-rays and fewer of them needed follow-up surgery.
Pain professor couldn’t be properly pain-managed
Professor of Health Psychology at the Department of Psychology at Aarhus University and Aarhus University Hospital, Bobby Zachariae, experienced inadequate pain management during treatment for a broken wrist – an experience he shared with Danish Broadcasting Corporation (DR).
This is exactly the challenge we are addressing in The BLOCK Trial: How can we ensure better pain relief and an improved patient experience?
