Ulnar (cubital) nerve compression at the elbow or wrist

ULNAR (CUBITAL) NERVE COMPRESSION at the elbow or wrist

Aside from carpal tunnel syndrome (a compression of a nerve in the wrist which represents THE SINGLE MOST COMMON HAND PROBLEM (click here), there is a 2nd nerve which may cause problems and pain if it becomes compressed. This is the ulnar nerve (see diagram).
This ulnar nerve goes through 2 very tight anatomic spaces: one at the elbow, and one at the side of the wrist.

cubital

Compression of this nerve in either location causes pain and numbness of the little and ring fingers, and over time can even lead to weakness of hand function.
This condition is diagnosed by the physical examination of your arm by a certified hand surgeon and is confirmed with a lab test called an electromyogram (EMG).
