Q

Sensory loss to the 4th and 5th finger would cause concern for which structure?

Would you expect the damage to be before the plexus? At the elbow? Or in the hand?

And why?

A

Ulnar Nerve

In the Hand

Damage in any of the other places would present with sensory loss elsewhere, not just the 4th and 5th fingers.
