Interesting sensory exam in ulnar neuropathy

Benjamin Gilliotte3/10/26 4:39 PM (CDT)

Hello everyone.  Over the years I have  examined a number of patients who present with signs and symptoms of ulnar neuropathy, but when doing their sensory examination they report abnormal sensation on the lateral half of the ring finger instead of the medial half.  Many report that the medial half feels normal but the pinky finger and the lateral side of the ring finger have reduced or altered sensation.  I am wondering if anyone else has observed this and if there is a good explanation for it? (some may have had coexisting CTS of course but not all of them did). Thanks!

I enjoy participating in the AANEM Connect Forum for a number of reasons. There are very fundamental questions posed on a frequent basis that cause me to pause and ask myself, ‘Why didn’t I think of that?’ Also, I continue to learn new things when others contribute their thoughts and experiences. Connect is an excellent opportunity for members to interact and to address any topic, including those that may not be discussed at an annual meeting or journal article.
