Nerve constriction syndromes - Carpaltunnelsyndrome

In a nerve constriction syndrome, the effect of pressure leads to numbness, discomfort and pain, preferably at night in the body region supplied by this nerve. The longer the constriction persists, the more severe and lasting the damage. An operation can give the nerve more space and is superior to other treatments, especially in advanced stages.

The operation is performed in a bloodless state and with the help of magnifying glasses in order to better differentiate the fine tissue structures.

What's carpal tunnel syndrome?

If the bottleneck lies on the flexural side of the wrist in the carpal tunnel, the thumb, index finger, middle finger and partly the ring finger fall asleep. The carpal tunnel contains flexor tendons and the median nerve, which are spanned by a ligament. Access is between the ball of the thumb and the ball of the little finger. The nerve is released from adhesions using microsurgical techniques and the spanning ligament is extended. With appropriate aftercare, a small, fine, inconspicuous scar remains.

How can you prepare for the procedure?

  • All your questions about possible complications and alternative treatments should be answered in advance.
  • Keep nicotine and alcohol consumption to a minimum! Surgeries will limit your ability to travel by air.
  • Therefore, do not plan any professional or private air travel in the 4 weeks after the operation!
  • Lay down at home ice cubes or cooling pads ready to cool the skin after surgery!

How is the procedure performed?

  • The outpatient procedure is performed under local anesthesia and lasts approx. 30 minutes.

What do you need to keep in mind after the procedure?

  • The raising and cooling of the hand in the first 72 hours is very important.
  • Complete fist closure and finger stretching exercises should be performed several times per hour.
  • The skin threads are removed after 10 to 14 days.
  • Postoperative clinical controls are recommended on the 3rd postoperative day and after 1 and 2 weeks.
  • Independent scar massage from the 3rd postoperative week with moisturizing ointment (e.g. Bepanthen® wound and healing ointment, Linola® fat cream) helps to create inconspicuous soft scars.
  • Different slight touch stimuli of the fingertips, such as learning Braille, promote the recovery of the nerve.
