The second group - retroclavicular group - will receive an ultrasound-guided brachial plexus block via the retroclavicular approach, by injection of 30 ml of a mixture of ropivacaine 0.5 % + mepivacaine 1 %. Primary outcome is success rate at 30 minutes after the injection defined as loss of sensation to pinprick in the forearm and hand.
