Ulnar Tunnel Syndrome of the Wrist
What Is Ulnar Tunnel Syndrome of the Wrist?
Ulnar tunnel syndrome occurs when the ulnar nerve is compressed at the wrist. The ulnar nerve is one of the three main nerves that provide feeling and function to the hand. It travels from your neck down into your hand, and can be constricted in several places along the way.
When pressure on the nerve occurs at the wrist, it causes numbness and tingling in the little finger and along the outside of the ring finger. In addition, ulnar tunnel syndrome can sometimes cause weakness of hand pinch and grip.
What Causes Ulnar Tunnel Syndrome of the Wrist?
The most common cause of ulnar tunnel syndrome is a soft tissue tumor, usually a benign (noncancerous) cyst called a ganglion which originates from the wrist joint.
Other frequent causes are repetitive trauma or chronic pressure applied to the area of the hand.
Repetitive trauma can result from the use of a jackhammer. Chronic pressure can occur in the hand of a bicyclist against the handlebars
What Are The Symptoms of Ulnar Tunnel Syndrome of the Wrist?
Symptoms develop gradually. Weakness and increasing numbness, particularly on the little finger side of the hand are usual signs of ulnar tunnel syndrome. The degree of weakness and numbness depends on the location of the pressure point. Pain may or may not be present.
As the syndrome progresses, it may become more difficult to open jars, hold objects, or coordinate the fingers during such tasks as typing or playing a musical instrument.
What Are The Treatment Options For Ulnar Tunnel Syndrome of the Wrist?
Treatment depends on what is causing pressure on the nerve. For example, if the pressure is caused by the way the wrist is positioned when typing, a change in wrist position or the addition of some padding may be recommended.
In the case of a jackhammer operator, the person must eliminate the repetitive trauma by altering their technique, using protective padding or changing jobs.
A cyclist may relieve chronic pressure by frequently changing hand position on the handlebars and/or by adding protective padding.
In many cases of ulnar tunnel syndrome, anti-inflammatory medications, such as aspirin or ibuprofen, may alleviate symptoms. Short-term use of a wrist splint may be helpful.
Most cases of ulnar tunnel syndrome are caused by a growth at the wrist. The growth must be removed surgically. An experienced hand surgeon can remove cysts, scar tissue, or other causes of compression on an outpatient basis.
Once the pressure point is removed, the feeling will return and the numbness and tingling will decrease. It will take several months for the nerve to re-grow and heal completely. Postoperative rehabilitation and exercises will be prescribed by the surgeon.
