What Is Ulnar Neuropathy?
Ulnar neuropathy, also known as cubital tunnel syndrome, puts pressure on the ulnar nerve each time the elbow is bent, reducing the supply of blood to the nerve. This causes damage to the nerve over time. Hitting the “funny bone” pulls the ulnar nerve into the bony groove of the cubital tunnel, causing the characteristic tingling sensation in the small and ring fingers.
A general weakening of the motor function of the hand may make it easy to drop things or make it difficult to open jars. It may be difficult to coordinate the fingers while typing or playing the guitar, piano, or violin. The problem usually worsens with activities or occupations that are practiced over an extended period of time.
A timely diagnosis is imperative to minimize functional impairment, limb weakness, loss of dexterity and pain.
