Prior to a needle fasciotomy or needle aponeurotomy you will be prepared as if you are having an open operation, but the skin will not be cut. Your hand will be cleaned with disinfectant, and local anaesthetic is put in to numb the skin. The lump of scar tissue which is causing the contracture (known as the cord) is then divided using the tip of a needle with a windscreen wiper motion. The finger is then gently pulled to crack any remaining bits of the cord, and the procedure is complete. A small dressing is applied to the hand, and you are free to go home straight away.
After the procedure there is usually a lot of bruising in the hand. There may be numbness from the local anaesthetic lasting for a few hours. In the overwhelming majority of cases there is not wound in the skin, and you can go back to normal use of your hand the next day. In rare cases the skin may tear a little when bringing the finger straight, and a dressing might be required for a week or so.
