Carpal tunnel syndrome is a condition where pressure on the median nerve passes through the wrist into the hand, causing pain, pins and needles, weakness and numbness in the hand.
The operation
Carpal tunnel decompression is usually carried out under local anaesthetic. A cut is made on the palm of the hand, usually 2 inches long. The surgeon will release the ligament, which forms the roof of the tunnel. This relieves the pressure on the median nerve.
Pain
You may feel some pain and discomfort when the local anaesthetic wears off. Simple pain killers such as paracetamol and/or ibuprofen should be bought to use at home.
Stitches and Wound Care
You will be advised of the type of stitch and when to have them removed, usually at your G.P surgery. A cotton wool and crepe bandage will be in place over the dressing to prevent bleeding and swelling. Please keep the dressing and bandage clean and dry. If necessary, you may go home wearing a sling. You will be advised when to remove this. Following the operation, you will have a scar in the palm of your hand, which will be somewhat firm to touch and tender for 6-8 weeks. Massaging the area firmly with moisturising cream can help this.
Possible Complications
As with any operation there is a risk of infection. Should this occur, a course of antibiotics may be required; signs of infection are pain, inflammation and heat, please consult your GP.
Occasionally the hand may become swollen, painful and stiff following the operation. It is advisable to exercise.
The following exercises will help restore wrist strength, reduce swelling and increase movement, and help restore wrist strength. It is advisable to start on the first day after the operation and to repeat 3 times a day. (These exercises will not damage your stitches)
-
Try to fully bend all your fingers, including thumb, i.e. make a fist.
-
Try to fully straighten all your fingers and thumb.
-
Take your thumb across the palm to touch all the fingertips in turn as well as the base of the little finger.
-
Spread the fingers as wide as possible.
-
Bend and straighten your wrist.
Returning to work
Generally, if your hand is comfortable and mobile, you may return after seven days if you have a sedentary job. Manual workers may be unable to return to work for a period of 6-8 weeks.
Driving
You can drive after one week if you are comfortable and have regained all finger movements.
Follow up
You will be told before you leave the unit if a follow up is required. The appointment will then be sent through the post
