Review Question - QID 220010

A 46-year-old avid cyclist presents to the orthopedic clinic with a chief complaint of numbness over the small and ringer finger. The patient reports that he initially felt numb in the small and ring fingers only while doing long bike rides on the weekends. However, his sensation has diminished over the past few months even while doing daily activities. On physical exam, he has 5/5 strength with index finger abduction. His 2-point discrimination measures 10mm over the volar small and ring finger with no change in sensation over the ulnar dorsal hand. What is the most likely combination of peripheral nerve and location of compression?
