Your has recommended that you undergohand surgery to treat carpal tunnel syndrome. But what exactly is carpal tunnel syndrome? The median nerve, which carries sensationto the thumb and first three fingers, passes through a natural passageway in the wrist.This opening called the carpal tunnel is formed by archshaped wrist bones and a connectingligament. Various conditions, such as pregnancy, injury,arthritis and changes in the tendons caused by repetitive motion can crowd the alreadynarrow tunnel, putting pressure on the nerve. This added pressure can cause a tingling sensationin the fingers and the thumb and may even
lead to numbness, pain and restricted movement.This combination of symptoms is called the carpal tunnel syndrome. Your Procedure: On the day of your operation, you will beasked to put on a surgical gown. You may receive a sedative by mouth and an intravenous line may be put in. You will then be transferred to the operatingtable. Your will scrub thoroughly and willapply an antiseptic solution to the skin around
the area where the incision will be made. Next, the surgeon will numb the involved areaof the hand and wrist with an anesthetic, either with a local injection or by completelyblocking a nerve higher up on the arm. When the operative field is completely numbthe surgeon will make an incision. Skin and other tissue will be carefully drawnaside to expose the carpal ligament. Then the surgeon will cut the ligament, relieving pressure on the nerve that runsbeneath it. Finally the will close the incisionwith fine sutures.
A sterile bandage will be applied and a splintwill be put in place to prevent the wrist from moving while healing takes place.
Carpal tunnel syndrome animation
Carpal tunnel syndromeis a common condition that causes pain and numbnessin your hand and fingers. It affects one of the main nervesin your hand. It travels from the armpit, down the arm and through the carpal tunnelat the wrist into the hand. The carpal tunnelis a narrow passage in your wrist made up of small bones. And a tough band of tissue.
The carpal tunnel protects the mediannerve and tendons that pass through it. These tendonsmove your fingers and wrist and the median nervecontrols your thumb muscles and gives you feeling in your hand. If the narrow spaceinside the carpal tunnel is reduced, it can put pressure on the median nerve.This is known as: It can be caused by:. .or a conditionsuch as rheumatoid arthritis
which causes swelling around the wrist. When the median nerve is compressed,it may cause pain, numbness, and a burning or tingling sensationin your hand and fingers. The muscles in your thumbmay also become weak, making it difficult to grip objects. Carpal tunnel syndromeoften goes away without treatment, which is common in pregnant womenand those under the age of 30. If your symptoms are mild to moderate,
carpal tunnel syndromecan be treated with a wrist splint or antiinflammatory medicinesto reduce the swelling. However, if your symptoms are severe,and no other treatment has worked, your may recommendyou have surgery known as: You will be given an injection,local anaesthetic, to numb your hand and arm. Your surgeon will useeither open surgery or keyhole, laparoscopic, surgery.
In open surgery, a single incisionis made along the base of your palm and a cut is madein the carpal ligament to release the pressureon the median nerve. In keyhole surgery, a smaller incisionis made above the wrist and a tube with a small camera,endoscope and special instruments are used to cut the carpal ligament. There is a slightly shorter recoverytime when keyhole surgery is performed, although there is no real differencein the success of the two operations.
