Prevention

If you type or use a computer keyboard, you can decrease your risk of carpal tunnel syndrome by making sure that you work in a "wrist neutral" position, with the wrist joint straight, not bent up or down. To help you do this, several types of office aids are available, including a cushioned wrist rest and a keyboard tray that adjusts to a position below the work surface. Newer types of keyboards are being developed, including ones that split the keys into left-hand and right-hand groups, and others that bend the keyboard into a tent shape. You also may need to check the position of your hand when you use a computer mouse or trackball because some experts suspect that people who use these computer accessories consistently are more likely to develop carpal tunnel syndrome. If you continue to have symptoms, you may want to have a professional check your workstation.

To prevent sports-related carpal tunnel syndrome, ask your trainer or a sports medicine physician about effective ways to support your wrist during high-risk activities.

Treatment

In most cases of carpal tunnel syndrome, treatment begins with a wrist splint to be worn mainly at night. You may also receive anti-inflammatory medication to decrease pain and numbness. Injections of cortisone may help reduce swelling, but they tend to provide only temporary relief. For people who do not improve with nonsurgical treatments, surgery can be done to relieve pressure on the median nerve by cutting a ligament at the bottom of the wrist, which creates more room for the nerve in the carpal tunnel.
