Cubital tunnel syndrome

Do you have numbness or tingling in one or more of your ring fingers or little fingers? Perhaps you’re experiencing a loss of finger or hand strength. Orthopaedic surgeon Lorcan McGonagle of LMcG Orthopaedics in Geraldton outlines the signs, symptoms and treatment options.

What is the cubital tunnel?

The cubital tunnel is a narrow groove in a bone near your elbow. This groove provides a passage for the ulnar nerve, one of the main nerves in your arm. The ulnar nerve can cause “funny bone” pain if you bump your elbow. Your cubital tunnel helps protect this nerve where it goes through your elbow and down to your fingers.

What are the signs and symptoms of cubital tunnel syndrome?

Numbness or tingling in the ring fingers and little fingers
Loss of finger or hand strength
Inability to straighten fingers
Sharp, sudden pain when the elbow is touched
Shrinking of hand muscles

What are the risk factors for developing cubital tunnel syndrome?

Common risk factors include:

Keeping arms bent regularly
Leaning on the elbows for extended periods
Intense physical activity
Arthritis
Bone spurs
Previous elbow fractures or dislocations
Pulling, lifting or reaching for items on a continuous basis
Using vibrating tools regularly
Lifting weights that are too heavy

Will cubital tunnel syndrome go away on its own?

Cubital tunnel syndrome may go away on its own. In other cases, you may need Nonsteroidal anti-inflammatory drugs (NSAIDs) to decrease your symptoms. These medicines decrease swelling and pain. Your doctor will explain which medicine is right for you and how much to take.

Is surgery recommended for cubital tunnel syndrome?

If your symptoms do not respond to conservative treatment or if the pain is severe, surgery may be necessary. Your doctor may recommend surgery if you are experiencing muscle loss or weakness in your hands because of cubital tunnel syndrome. During the procedure, your orthopaedic surgeon will expose the irritated, compressed or stretched ulnar nerve and either release it, move it or remove part of it.

What are the risks and complications of cubital tunnel syndrome surgery?

Most patients suffer no complications following cubital tunnel surgery. In general, elbow surgery complications can include infection, nerve damage, elbow instability and elbow flexion contracture.
