Ultrasound-guided Infraclavicular Block With Lidocaine or Ropivacaine for Closed Reduction of Distal Radius Fractures

To investigate the feasibility of the lateral infraclavicular plexus brachialis (LIC) block for acute closed reduction of distal radius fractures, the investigators will compare the pain-relieving and muscle-relaxing properties of the LIC block with short- and long-acting local anesthetics in different concentrations but at the same volume. In addition to motor and sensory blockade during repositioning, feasibility will also be assessed by other patient-related and block-related factors, as well as by factors related to the repositioning and plastering procedure.
