The goal of this clinical trial with medical device is to learn if the Smart Needle Monitoring System works to maintain a safe low injection pressure during a type of regional anaesthetic (Peripheral Nerve Block (PNB)) in patients due to undergo surgery below the elbow . It will also learn about the safety of the device and patients' perception of the quality of anesthesia.
Participants will:
* be operated locally according to standard clinical practice * undergo post-anesthesia recovery and any neurologic symptoms or signs assessment on postoperative days 1 and 7
