What It Is

Cubital tunnel syndrome happens when the ulnar nerve in the arm becomes irritated or compressed (squeezed) at the elbow (AAOS, n.d.). The ulnar nerve is one of the three main nerves in your arm. It travels from your neck down into your hand, and it can be squeezed in several places along the way, such as beneath the collarbone or at the wrist (AAOS, n.d.). Most of the symptoms are felt in the hand: typically numbness and tingling in your little finger and ring finger, which often come and go. There can also be an aching pain on the inside of the elbow. Later-stage or more severe compression can cause a weak grip and difficulty with finger coordination (AAOS, n.d.).

The most common place for the ulnar nerve to be squeezed is behind the inside of the elbow, next to where your "funny bone" is – this is cubital tunnel syndrome (AAOS, n.d.). A pinched nerve in the neck can cause similar symptoms (AAOS, n.d.), so if you also suffer with neck pain, simply let me know so I can check your neck.

Cubital Tunnel Syndrome Anatomy

Around the elbow, the ulnar nerve travels through a tunnel of tissue (the cubital tunnel) that runs underneath a bony bump on the inside of the elbow. The bony bump is called the medial epicondyle. The spot where the nerve runs under the medial epicondyle is commonly called the funny bone. At the funny bone, the nerve lies close to the surface of the skin, and if it is bumped it causes a feeling like a small electric shock (AAOS, n.d.).

In many cases, there is no obvious cause (AAOS, n.d.; BSSH, n.d.). Things that can put pressure on the nerve include leaning on your elbow for long periods, keeping your elbow bent for long periods or bending it repeatedly (such as holding a phone), sleeping with your elbow bent, arthritis or bone spurs at the elbow, swelling or cysts near the elbow joint, and the large stress that throwing a baseball puts on the inside of the elbow (AAOS, n.d.; BSSH, n.d.).
