Cubital Tunnel Syndrome is a condition that involves pressure or stretching of the ulnar nerve (also known as the “funny bone” nerve), which can cause numbness or tingling in the ring and small fingers, pain in the forearm, and/or weakness in the hand.
There are a few causes of this ulnar nerve problem. These include:
Cubital tunnel syndrome can cause pain, loss of sensation, tingling and/or weakness.
“Pins and needles” usually are felt in the ring and small fingers.
These symptoms are often felt when the elbow is bent for a long period of time, such as while holding a phone or while sleeping.
Some people feel weak or clumsy.
Your doctor can learn much by asking you about your symptoms and examining you.
S/he might test you for other medical problems like diabetes or thyroid disease.
Sometimes, nerve testing (EMG/NCS) may be needed to see how much the nerve and muscle are being affected.
This test also checks for other problems such as a pinched nerve in the neck, which can cause similar symptoms.
The first treatment is to avoid actions that cause symptoms.
Sometimes, surgery may be needed to relieve the pressure on the nerve.
This can involve releasing the nerve, moving the nerve to the front of the elbow, and/or removing a part of the bone. Your surgeon will talk to you about options.
Therapy is sometimes needed after surgery, and the time it takes to recover can vary.
Numbness and tingling may improve quickly or slowly. It may take many months for recovery after surgery.
Cubital tunnel symptoms may not totally go away after surgery, especially if symptoms are severe.
