- Brief 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.

Group Intervention Description Blind hematoma block Blind hematoma block Patients in this group will receive standard treatment; hematoma block with palpation of the fracture site (blind hematoma block) Ultrasound guided hematoma block Ultrasound guided hematoma block. Patients in this group will receive ultrasound guided hematoma block before reduction of their dislocated distal radius fracture.
- Primary Outcome Measures
Name Time Method Effectiveness of analgesia during closed reduction of a distal radius fracture NRS before, during and after (10-15 min) injection of hematoma block, NRS-score during closed reduction and after closed reduction (5 min) Pain reduction will be measured on a Numeric Rating Scale( NRS-scale; 0-10) at different moments
- Secondary Outcome Measures
Name Time Method Number of participants in which hematoma was aspirated during hematoma block During hematoma block Measure of correct position of hematoma block if there is aspiration of blood (yes/no)
Procedural time of the reduction From moment physician is ready to start the reduction until cast is applied (up to maximum of 30 min.) Time needed to perform reduction of the fracture
Procedural time of the Hematoma block Time from insertion of the needle until needle is withdrawn out of the patient (up to maximum of 30 min.) Time needed to perform HB (blind or ultrasound-guided; from moment of localization of the fracture until the moment the needle is out of the patient)
Satisfaction of reduction provided by physician performing reduction measured 10-15 minutes after closed reduction measured on a 5-points Likert-scale (Very satisfied, Somewhat satisfied, Neither satisfied nor dissatisfied, Somewhat dissatisfied or Very dissatisfied)
Satisfaction of the nurse for procedure and reduction 10-15 minutes after closed reduction measured on a 5-points Likert-scale (Very satisfied, Somewhat satisfied, Neither satisfied nor dissatisfied, Somewhat dissatisfied or Very dissatisfied)
Years of experience of treating physician with use of ultrasound. (up to) 10-15 minutes after last closed reduction attempt Years of experience of treating physician with use of ultrasound.
Satisfaction of the patient for procedure and reduction 10-15 minutes after closed reduction measured on a 5-points Likert-scale (Very satisfied, Somewhat satisfied, Neither satisfied nor dissatisfied, Somewhat dissatisfied or Very dissatisfied)
Number of reductions (up to) 10-15 minutes after last closed reduction attempt Defined as attempt(s) to align fracture and application of cast
Satisfaction of the HB provided by physician performing the HB procedure 10-15 minutes after hematoma block measured on a 5-points Likert-scale (Very satisfied, Somewhat satisfied, Neither satisfied nor dissatisfied, Somewhat dissatisfied or Very dissatisfied)
Number of patients in which palpation of an evident step-off near fracture site was felt During performing hematoma block Before performing hematoma block performing physician will palpate if there is a clear step-off near the fracture site (important especially in blind hematoma group)
Years of experience of treating physician in performing HB. (up to) 10-15 minutes after last closed reduction attempt Years of experience of treating physician in performing HB.
