A C7 radiculopathy commonly presents with sensory changes in which digit?

Explanation:
Cervical radiculopathy presents with sensory changes that follow the dermatomal distribution of the affected nerve root. For the C7 root, the dermatomal area includes the middle finger, so numbness, tingling, or altered sensation is most commonly felt there. The little finger is more associated with the C8 dermatome, while the thumb and index finger align with the C6 dermatome. Therefore, middle finger sensory changes are the best clue that the radiculopathy involves the C7 root.
