Summary

This study will investigate the effectiveness of analgesia of ultrasound hematoma block compared to 'blind' hematoma block in patients with dislocated distal radius fracture.

Detailed description

Distal radius fractures represent one of the most common injuries in the Emergency Department (ED). Proper treatment especially for dislocated fractures can minimize the chance of residual injury. For closed reduction anesthesia is essential for safety, satisfaction and result. Different methods of regional anesthesia can be used but hematoma block (HB) is the technique most often used in EDs in the Netherlands and recommended by Dutch guidelines. In practice however a HB, does not always lead to adequate anesthesia, this might be because of poor infiltration into the fracture site. Ultrasound could additionally provide real-time guidance of injection into the fracture site, maximizing the analgesic effect of HB. In this study the effectiveness of analgesia of ultrasound HB will be compared to 'blind' HB in patients with a dislocated distal radius fracture. Patients with a confirmed dislocated fracture of the distal radius requiring closed reduction will be randomized to either ultrasound guided hematoma block or normal 'blind' hematoma block. NRS-scores will be given before, during and after hematoma block and during and after reduction of the fracture. These scores will be the primary endpoint of this study.

Conditions

• Distal Radius Fractures
• Fracture Dislocation
• Dislocated Wrist
• Dislocated Radius

Interventions

Type	Name	Description
DEVICE	Ultrasound guided hematoma block.	Patients with a dislocated fracture of the distal radius will receive ultrasound guided hematoma block with 10mL lidocaine 2% to get real-time guidance of the given anesthesia into the fracture site before closed reduction of a distal radius fracture.
PROCEDURE	Blind hematoma block	Patients with a distal radius fracture will receive standard treatment; hematoma block with 10mL 2% lidocaine performed with palpation of the fracture site (blind hematoma block) before closed reduction of dislocated distal radius fractures.
