Cubital tunnel syndrome can cause hand and elbow pain, numbness and tingling

Cubital tunnel syndrome is an aggravating condition that also is referred to as ulnar nerve entrapment. The ulnar nerve, commonly called the funny bone, extends from the elbow to the hand and helps move the forearm, hand, ring finger and pinky.

The ulnar nerve travels through tissues called the cubital tunnel. When this nerve becomes irritated or compressed, it can cause pain, numbness and tingling. If left untreated, it can lead to muscle weakness and atrophy.

Cubital tunnel syndrome can occur over time from thickening of soft tissues over the nerve or keeping the arm in one position too long, such as repeatedly leaning on an armrest, which can cause the sensation of feeling like your arm, hand, ring finger and/or pinky is asleep.

The nerve also can snap instead of staying in place, making it seem as if your arm is stuck. Sleeping with the arm bent also can overstretch the nerve and lead to noticeable symptoms.

Symptoms:

• Numb or tingling fingers that feel asleep.
• Hand and finger numbness or tingling that comes and goes.
• Pain on the inside of the elbow.

Cubital tunnel syndrome can be diagnosed with blood tests, an electromyogram (EMG) or X-rays. If you have elbow issues, such as arthritism, bone spurs, cysts or past elbow dislocation or fracture, you may be at greater risk for ulnar nerve entrapment.

Non-surgical treatments include using a splint or brace, hand therapy, exercises and non-steroidal medication. Surgery can include release of the cubital tunnel or procedures to shift the ulnar nerve.
