CTS involves paresthesias in which digits?

Explanation:
Carpal tunnel syndrome disturbs sensation in the median nerve distribution of the hand. That means paresthesias appear on the palmar surface of the thumb, index finger, middle finger, and the radial (lateral) half of the ring finger. The little finger and the ulnar half of the ring finger are supplied by the ulnar nerve, so they are not typically affected by CTS. Sensation on the dorsal hand can be less involved, as the median nerve mainly carries palmar finger sensation, especially in CTS.
