Brachial Plexus Nerve Block Versus Haematoma Block for Closed Reduction of Distal Radius Fracture in Adults - The BLOCK Trial. A Multicentre Randomised Controlled Trial.

The aim of the project is to evaluate the beneficial and harmful effects of an ultrasound-guided brachial plexus nerve block for patients with a distal radius (wrist) fracture in the need of realignment of fractured bone endings without cutting the skin (closed reduction), in comparison to a haematoma block, which is standard care in Denmark. Every participant will receive one of the following types of anaesthesia for the realignment of the wrist fracture: 1. A nerve block of the arm (plexus brachialis block) 2. A haematoma block, which is the current standard anaesthesia in the emergency departments.
