Other symptoms include:.

Doctors can diagnose carpal tunnel syndrome using a combination of your history, a physical examination , and tests called nerve conduction studies. A physical examination includes a detailed evaluation of your hand, wrist, shoulder, and neck to check for any other causes of nerve pressure.

Your doctor will look at your wrists for signs of tenderness, swelling, and any deformities. They will check sensation to the fingers and strength of the muscles in your hand. Nerve conduction studies are diagnostic tests that can measure the conduction speed of your nerve impulses. If the nerve impulse is slower than normal as the nerve passes into the hand, you may have carpal tunnel syndrome.

Treatment of carpal tunnel syndrome depends on how severe your pain and symptoms are and if there is weakness. In , the Academy of Orthopaedic Surgeons released guidelines for the effective treatment of carpal tunnel. The recommendation was to try to manage carpal tunnel pain without surgery, if possible. Surgery for carpal tunnel syndrome involves cutting the band of tissue in the wrist that crosses the median nerve so as to lessen the pressure on your nerve.

Factors that determine success or failure are age of the patient, duration of symptoms, diabetes mellitus, and if there is weakness which usually is a late sign.

The outcome is usually good. You can prevent carpal tunnel syndrome by making lifestyle changes that reduce your risk factors for developing it. Treating conditions such as diabetes, high blood pressure, and arthritis reduces your risk for developing carpal tunnel syndrome.

Try these 10 exercises to help prevent…. Common surgical treatment for CTS usually involves the severing of the ligament around the wrist to alleviate pressure on the median nerve.

Physicians usually use open release surgery or endoscopic surgery to achieve this goal. Open release surgery is typically done under local anesthesia, and it involves making an incision of approximately two inches in the wrist to severe the carpal ligament and enlarge the carpal tunnel.

Endoscopic surgery, on the other hand, has faster recovery time and minimal post-op discomfort than the open release surgery. However, it comes with a higher risk of complications. The tube also has a knife that the physician uses to nick the carpal ligament. The surgical severing of the carpal ligament relieves the pressure on the median nerve, and during recovery, the ligament can regrow.

Post-operative recovery for CTS treatment usually takes several months to one to two years. Grip and pinch strength may not improve to functional conditions for three to six months. Timeline for recovery usually depends on several factors including the continuation of post-surgical therapy, the absence of nerve damage, and infection at surgical sites. Carpal Tunnel or Carpal Tunnel Syndrome CTS can be prevented by adopting safe ergonomic measures such as proper posture, stretching, and reducing or avoiding prolonged repetitive activities.

Workers should take breaks following overuse of hand. Employers should incorporate workstations that enable workers to work in safe, natural positions. Citations 1. Carpal Tunnel Syndrome Fact Sheet.
