No peer-reviewed publication reporting this trial's results has been linked yet. This can indicate results are unpublished — a known publication-bias signal. We re-check periodically.
Summary
The aim of this clinical trial is to determinate if distal ultrasound guided peripheral nerve blocks on target nerves (radial and median nerve blocks at the elbow), using low volume and low concentration of long acting local anesthetic provide better postoperative pain control compare with systemic analgesia alone after thumb resection arthroplasty (TRA) due to a prolonged selective sensitive block on the tissue trauma.
