Continuous regional anesthesia through a catheter placed in the axillary sheath has been an effective method of brachial plexus neural blockade. This article confirms this observation and demonstrates that continuous axillary block is useful in replantation surgery to provide anesthesia and analgesia in addition to sympathetic blockade for up to 7 days after operation. This anesthetic technique may allow extensive revascularization or replantation procedures to be performed for patients who could not safely tolerate prolonged application of general anesthesia.

Pigmented villonodular synovitis of the wrist joint invading adjacent bones rarely occurs. A case in which synovitis invaded the carpal and metacarpal bones at the ulnar aspect of the wrist is described. The invasion of multiple bones by the tumor and its histologic hypercellularity in this case caused concern because of its aggressive behavior. However, review of the literature on pigmented villonodular synovitis arising at the wrist and invading adjacent bones and follow-up of our patient confirmed its benign character.
