Cubital Tunnel Syndrome

Cubital tunnel syndrome is also known as ulnar neuropathy. Cubital tunnel syndrome is caused by increased pressure on the ulnar nerve, which passes close to the skin’s surface in the area of the elbow. You’re more likely to develop cubital tunnel syndrome if you:

    • Repeatedly lean on your elbow, especially on a hard surface
    • Bend your elbow for sustained periods, such as while talking on a cell phone or sleeping with your hand crooked under your pillow.

Early symptoms of cubital tunnel syndrome include:

    • Pain and numbness in the elbow
    • Tingling, especially in the ring and little fingers

More severe symptoms of cubital tunnel syndrome include:

    • Weakness affecting the ring and little fingers
    • Decreased ability to pinch the thumb and little finger
    • Decreased overall hand grip
    • Muscle wasting in the hand
    • Claw-like deformity of the hand
