2. Anatomy of the Pinky Finger and Nerve Supply
To fully understand why your pinky finger might go numb, it’s helpful to know a bit about its anatomy, especially its nerve supply. The pinky finger, also known as the fifth digit, consists of three bones called phalanges: the proximal, middle, and distal phalanges. These bones are connected by joints, allowing for flexibility and movement.
The primary nerve responsible for sensation in the pinky finger is the ulnar nerve. This nerve originates in the neck, travels down the arm, and passes through the elbow before reaching the hand. As it enters the hand, the ulnar nerve travels through a space called Guyon’s canal, located on the pinky side of the wrist. From there, it branches out to provide sensation to the pinky finger and the outer half of the ring finger.
The ulnar nerve is vulnerable to compression or injury at several points along its path, including the elbow (cubital tunnel syndrome) and the wrist (Guyon’s canal syndrome). Understanding the anatomy of the ulnar nerve and its pathway helps explain why compression or damage to this nerve can result in numbness in the pinky finger.
