Do you have any questions? Introduction Please use the space below to remind you of what you want to ask. ----------------------------------------------------------------------------------------- Nerves are more sensitive to pressure changes than most body parts. Continuous or periodic compression on a nerve can cause damage over time. Certain nerves are located in regions of the body that are especially vulnerable to compression injuries. The most common is the Carpal Tunnel. Illustrations used by kind permission of the Arthritis Research Campaign (www.arc.org.uk). Carpal tunnel syndrome The Carpal Tunnel is a narrow, channel formed by the carpal bones of the wrist. The median nerve enters the hand through the carpal tunnel. Inflammation of the muscles, tendons or a fracture of the wrist can reduce space in the carpal tunnel and so cause pressure on the nerves. ----------------------------------------------------------------------------------------10 Oedema - increased fluid in the carpal tunnel due to tissue injury, congestive cardiac failure or pregnancy Fractures - Fractures and dislocations of the wrist, displaced bones or spurs disrupt the carpal tunnel 3
Carpal tunnel size - inherited small bone structure may lead to increased evidence of carpal tunnel syndrome Hypothyroidism Symptoms of carpal tunnel syndrome are:a dull ache in the wrist and forearm with pain radiating in to the fingers A burning pain in the wrist with numbness or loss of feeling in the thumb, index finger and middle finger which the median nerve supplies Pain which is worse at night Conservative treatment Resting the hand Wearing a wrist splint at night Modify hand activity and work environment Steroid injections or thyriod replacement Surgery In moderate and severe cases, surgery may be necessary. The aim of surgery is to prevent further damage to the nerve. The nurse discharging you will provide you with a discharge sheet for your own reference, a letter for your G.P, a sick note, should you require one, and any medications required Arrangements will be made to have your sutures removed, usually after 10-14 days Your follow up appointment will be made for 6 weeks following surgery When may I return to work? It is advisable to wait until after your sutures are removed before returning to work or driving a car. Manual worker may require a little more time to recover and return to work.
