Cubital Tunnel Syndrome (Ulnar Nerve at the Elbow)
The ulnar nerve passes behind the elbow — the “funny bone” — and can be compressed there, causing numbness in the ring and little fingers and weakness of the hand. Avoiding prolonged elbow bending and padding the elbow help early cases; persistent symptoms or weakness are treated with decompression.
Symptoms
- Numbness of the ring and little fingers
- Symptoms with elbow bending, phone use, sleeping
- Weak grip, clumsy hand
- Wasting between the thumb and index finger (advanced)
How it is diagnosed
Examination and EMG/NCS.
Treatment options
Without surgery
Elbow padding, night splinting, ergonomic changes.

Common questions
Why does it get worse at night?
Most people sleep with the elbow bent, which stretches and compresses the ulnar nerve for hours. A simple night splint or a towel wrapped around the elbow to keep it straighter often helps within weeks.
Release or transposition?
A simple release (in-situ decompression) frees the nerve where it is pinched and is enough for most patients. Moving the nerve to the front of the elbow (transposition) is reserved for cases where the nerve slips out of its groove or the elbow is deformed.
How long until the numbness goes?
Symptoms present for months usually improve over weeks; long-standing numbness with muscle wasting recovers partially, which is why earlier treatment gives better results.
Not sure this is you?
Bring your imaging and your story. A single visit usually clarifies what is going on and which options are realistic. Request an appointment or call (301) 718-9611.
