2. Figure 1
Tug test (). The index finger is directed posteriorly in the subdeltoid space while the other index finger is placed medially into the subcoracoid space and over the axillary nerve. A gentle tug on the nerve with the subdeltoid index finger can be transmitted across the nerve and felt with the other index finger, confirming that the nerve has been correctly identified.
