Role of Sensory Innervation Variations for Wrist Block Anesthesia

Background ety of anesthesia techniques for hand surgery have been suggested. s of single peripheral nerve block and incomplete wrist block failures are analyzed and compared with a group of patients with complete wrist block. s ing to the results of our study, in 825 cases there was a 15% rate of documented failures of incomplete wrist block, most probably due to anomalous sensory innervation. sions linical observation is in agreement with many published studies on neural anatomy and supports the use of complete wrist block for hand surgery.
