Carpal tunnel syndrome key points
These are the problems that you report to the doctor
- Pins and needles in the thumb, index and middle fingers
- Especially worse at night
- Wake from sleep and shake hand to gain relief
These are the physical abnormailites your doctor may see
- Wasting on the heal of the hand on the thumb side (thenar eminence)
- Tinel's Sign : tapping the nerve on the front of the wrist causes pins and needles into the thumb, index and middle fingers
- Modified Phalen's Sign : bending the wrist forwards towards the palm especially if the doctor presses on the nerve at the front of the wrist reproduces your symptoms
- Nerve conduction studies : small electrical pads are placed on the fingers and the speed of nerve impulse is recorded across the carpal tunnel. If it is slowed then it is likely the patient has carpal tunnel syndrome.
- None : Sometimes the symptoms and examination are classical of carpal tunnel syndrome and nerve conduction studies are not arranaged.
- Activity avoidence
- Steroid injection : usually only temporary
- Capral tunnel release : Simple procedure under local anaesthetic, operative time 10 minutes
