Cubital tunnel syndrome is a condition brought on by increased pressure on the ulnar nerve at the elbow. There is a bump of bone on the inner portion of the elbow (medial epicondyle) under which the ulnar nerve passes, which is commonly referred to as the “funny bone.” At this site, the ulnar nerve lies directly next to the bone and is susceptible to pressure. When the pressure on the nerve becomes great enough to disturb the nerve’s function, numbness, tingling and pain will develop in the elbow, forearm, hand and/or fingers. Numbness of the small finger and ring finger are typical symptoms of Cubital Tunnel Syndrome.
An Ulnar Nerve Entrapment may require Cubital Tunnel Release
surgery to alleviate the pressure on the ulnar nerve.
What Causes Cubital Tunnel Syndrome?
Pressure on the ulnar nerve at the elbow can develop in several ways: the nerve is positioned right next to the bone and has very little padding over it, so extra pressure can directly irritate the nerve. For example, if you lean your arm against a table on the inner part of the elbow, your arm may fall asleep and experience pain from sustained pressure on the ulnar nerve. If this occurs repetitively, the numbness and pain may be more persistent and the nerve can be permanently damaged.
Additionally, pressure on the ulnar nerve can occur from holding the elbow in a bent position for a long time, which stretches the nerve across the medial epicondyle. Such sustained bending of the elbow may tend to occur during sleep. Sometimes the connective tissue or surrounding muscle structure can cause pressure on the nerve. If the pressure on the nerve is significant enough, and sustained enough, it can irritate the ulnar nerve. If left untreated, cubital tunnel syndrome can lead to permanent numbness and tingling, a weak grip or irreversible “claw hand”.
No More Restless Nights
The compression of the median nerve causes shooting pain in the arm, shoulder, and the neck. This pain is most evident when sleeping. One of the first symptoms people with Cubital tunnel syndrome, or any other nerve-related condition, notice is restless nights caused by sharp, shooting pain.
With the AccuCision procedure, patients will regain their sleep, uninhibited by nerve pain, the same night.
