Compression of the ulnar nerve at the elbow (cubital tunnel) causes cubital tunnel syndrome. The sensory pattern follows the ulnar distribution of the hand, so numbness or tingling appears in the little finger and the ulnar half of the ring finger, typically on both the palmar and dorsal aspects. This contrasts with other nerves: the median nerve at the elbow would affect the index and thumb areas, the radial nerve would cause dorsal-hand numbness, and a median nerve issue at the wrist would involve the thumb. The described sensory loss—little finger and ulnar half of the ring finger—fits the ulnar nerve at the elbow, making that option the best choice.
