Peripheral Nerve Surgery

What is carpal tunnel decompression?

A carpal tunnel decompression, otherwise known as a carpal tunnel release, takes place if your neurosurgeon has diagnosed you with carpal tunnel syndrome.

This neurosurgery takes place when you are either under a local or a general anaesthetic. It requires you to fast from midnight before the operation.

Risks associated with a carpal tunnel decompression include

  • bleeding or blood clots after surgery
  • nerve damage
  • injury to surrounding blood vessels
  • infection
  • wrist pain
  • no improvement of your condition.

In a traditional carpal tunnel decompression, a neurosurgeon will begin by confirming the affected hand. They will make an incision at a patient’s wrist and cut through the flexor retinaculum, which protects the carpal bones and median nerve located at the wrist.

A neurosurgeon will divide the transverse carpal ligament to create space for the compressed median nerve, which passes through what’s known as the ‘carpal tunnel’ under the ligament.

The surgeon will finish by stitching the skin together. Then, a medical team will move a patient to recovery before transferring them to their ward.
