Blocco nervoso del plesso brachiale rispetto alla terapia standard per la riduzione chiusa della frattura del radio distale negli adulti: lo studio BLOCK. uno studio nazionale multicentrico randomizzato e controllato
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:
- A nerve block of the arm (plexus brachialis block)
- A haematoma block, which is the current standard anaesthesia in the emergency departments.

Armi e interventi
Gruppo di partecipanti / Arm |
Intervento / Trattamento |
|---|---|
|
Sperimentale: Intervention group
Ultrasound-guided brachial plexus nerve block. A total of 30 ml of lidocaine (10 mg/ml) with adrenaline (5 ug/ml) will be administered in multiple injections. |
The block will be performed as either a lateral infraclavicular brachial plexus block or an axillary brachial plexus block |
|
Comparatore attivo: Control group
Haematoma block with local anaesthetics i.e. lidocaine with adrenaline |
Participants will receive no peripheral nerve block and receive a haematoma block, with or without supplemental sedation and/or systemic analgesia for the closed reduction according to local guidelines and clinical practices |

Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Composite outcome of treatment related complications
Lasso di tempo: 90 days after closed reduction
|
loco-regional neurological complications from affected arm, local anaesthetic systemic toxicity, soft tissue injuries (including skin injuries) related to the closed reduction procedure, infection at the site of needle puncture, vessel puncture requiring subsequent treatment (including compression), pneumothorax, allergic reaction, new bone or joint injury (e.g. dislocation or fracture) after the closed reduction and/or pulmonary embolism |
90 days after closed reduction
|
|
Patient Rated Wrist Evaluation (PRWE)
Lasso di tempo: 90 days after closed reduction
|
The PRWE is a patient-reported outcome and the PRWE-score is calculated from the Danish-validated translation of the PRWE questionnaire |
90 days after closed reduction
|
|
Maximum pain score in the affected wrist during closed reduction(s)
Lasso di tempo: 0-12 hours after the closed reduction
|
The pain outcomes are patient-reported as a Numerical Rating Scale (NRS) score on a scale from 0=no pain to 10=worst pain imaginable. If the patient has the closed reduction performed more than one time, the patient will be asked to report the worst pain experienced during all the attempts of a closed reduction. |
0-12 hours after the closed reduction
|
|
Proportion of patients with unacceptable radiographic fracture position immediately after closed reduction
Lasso di tempo: 0 -24 hours after closed reduction
|
The radiographic fracture position is evaluated according to the American Academy of Orthopaedic Surgerons (AAOS) guidelines. The fracture position is unacceptable if the fracture has a radial shortening > 3 mm, > 10 degrees dorsal tilt of the articular surface of radius from a perpendicular line on the longitudianal axis of radius or intra-articular displacement or step-off > 2 mm. |
0 -24 hours after closed reduction
