Abstract
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.
