Role of sensory innervation variations for wrist block anesthesia.
BACKGROUND
A variety of anesthesia techniques for hand surgery have been suggested.


METHODS
Cases of single peripheral nerve block and incomplete wrist block failures are analyzed and compared with a group of patients with complete wrist block.


RESULTS
According 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.


CONCLUSIONS
This clinical observation is in agreement with many published studies on neural anatomy and supports the use of complete wrist block for hand surgery.
