The carpal tunnel is a passageway in the wrist formed by the carpal bones, which make up the floor and sides of the tunnel, and the transverse carpal ligament which forms the roof of the tunnel.
\n\n
\n\nInside the carpal tunnel are flexor tendons that bend your fingers and thumb. Also running through the tunnel is the median nerve, a cord about the size of a pencil containing thousands of nerve fibres supplying sensation to the thumb, middle and index fingers, and half the ring finger.
\n\n
\n\nCarpal tunnel syndrome is caused by increased pressure in the tunnel resulting in compression of the median nerve against the ligament. Blood flow to the nerve is restricted causing a sensation described as “pins and needles” to the fingers. Numbness and pain may also occur.
\n\n
\n\nThe procedure is performed as day surgery.
\n\n
\n\nThe operation lasts approximately 20-30 minutes.
\n\n
\n\nLocal anaesthetic and intravenous sedation are used.
\n\n
\n\nA small incision is made in the palm over the wrist area.
\n\n
\n\nThe surgeon will cut the ligament forming the roof of the tunnel which will relieve pressure
\n\non the median nerve.
\n\n
\n\nYour hand will remain numb for several hours due to the local anaesthetic.
\n\n\n\n
Symptoms may take some weeks to resolve.
\n\n
\n\n
\n\n
\n\nDo not drive for 24 hours after surgery.
\n\n
\n\nThe bandage may be removed when you wish.
\n\n
\n\nThe suture line must be kept dry and clean until suture removal 12-14 days after surgery.
\n\n
\n\nCover the affected hand with a plastic bag when showering.
\n\n
\n\nYou may move your hand as comfort permits, it is important to keep using it gently.
\n\n
\n\nUse analgesic medication as required.
\n\n
\n\nOnce the sutures are removed you may massage the incision line with cream (e.g. vitamin E cream).
