Arm nerve block tested to cut surgery after wrist fracture
NCT ID NCT06678438
First seen Sep 21, 2026 · Last updated Sep 21, 2026
Summary
Researchers compare two ways to numb the arm for realigning a broken wrist without surgery. Adults with a distal radius fracture receive either an ultrasound-guided brachial plexus nerve block or a haematoma block, the standard method in Danish emergency departments. The trial measures how many participants later need wrist surgery and tracks complications from each approach.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Ultrasound-guided brachial plexus nerve block
- What this could lead to
- If the nerve block works better, it could become the preferred way to numb the arm for realigning wrist fractures, potentially reducing the need for later surgery.
- What could go wrong
- Nerve blocks can cause nerve irritation or bleeding, and the trial may find no difference between the two methods. Results may not apply outside Denmark.

Inclusion Criteria: * Adults (age ≥ 18 years) with a distal radius fracture in need of closed reduction Exclusion Criteria: * Patients who would never qualify for surgery according to local guidelines * Lack of informed consent * No Danish Central Person Register (CPR) number * Allergies to the trial medication * Distal radius fracture initially deemed to require surgery regardless of the outcome of the closed reduction * Open fractures (fracture-related wound requiring sutures) * Other fractures on the same extremity ((NOT including distal ulna fracture(s)) * Bilateral distal radius fractures both requiring closed reduction * Concomitant medical or surgical condition taking priority over the closed reduction of the distal radius fracture.
