Carpal tunnel surgery Perth
Carpal tunnel
and nerve
decompression
Ever noticed your hand going numb for no reason? Or maybe you wake up at night with tingling in your fingers that you can’t shake off. These are common signs of nerve compression in the wrist (specifically, the carpal canal) and they can make everyday tasks surprisingly difficult.
At The Wrist + Hand Institute Perth, our wrist and hand surgeons treat these problems with minimally invasive nerve decompression surgery, often using advanced endoscopic techniques to help you recover faster and get back to what you enjoy.
Common concerns
Many people worry that surgery will mean a large scar, a long recovery or time off work they can’t afford. The reality is that modern endoscopic techniques often involve smaller incisions, less tissue disruption and quicker return to function. We’ll always discuss your options in detail, including non-surgical approaches where appropriate, so you feel confident in your decision.
What is carpal tunnel syndrome?
Carpal tunnel syndrome is caused by compression of the median nerve at the wrist in the carpal canal. It often leads to tingling, numbness or weakness in the thumb, index, middle and part of the ring finger.
What is cubital tunnel syndrome?
Other causes of numbness or weakness in the hand
Who this surgery is for
Nerve decompression surgery is generally recommended when:
- You have ongoing numbness, tingling or weakness
- Nerve tests (or ultrasound) show ongoing compression.
- Your symptoms are affecting your work, sleep or day-to-day life.
The most common procedures we perform for nerve compression are:
- Endoscopic carpal tunnel release: for compression of the median nerve at the wrist.
- Cubital tunnel release: for compression of the ulnar nerve at the elbow.
- Release of the ulnar nerve in Guyon’s canal (at the level of the wrist).
Types and options
Supra-retinacular endoscopic carpal tunnel release
This technique was pioneered by our surgeons, and has been published and presented internationally. It is safe as it allows visualisation of the anatomical structures in the carpal canal (like small nerves). A small camera and instruments are inserted through a 2–3 cm incision in the wrist flexion crease. It allows your surgeon to see and release the tight ligament pressing on the nerve without performing a long cut in your palm. This can reduce scarring and speed up your return to daily activities. The incision is covered by small water-proof adhesive dressings. In most cases, both the right and left side can be performed at the same time, minimising time off work and disruption to your life.
Cubital tunnel release
For ulnar nerve compression at the elbow, surgery can be performed using endoscopic (‘keyhole’) or open techniques. In both surgeries the tissue compressing the nerve is released. In some cases, the nerve is transposed to a position where it is better protected. Your surgeon will discuss which technique is right for you based on a number of factors including your symptoms and anatomy.
Release of the ulnar nerve from Guyon’s canal
Release of the ulnar nerve from Guyon’s canal is done via an open procedure with a 5-6 cm incision.
What happens in surgery?
The anaesthetic and hospital stay will depend on your procedure.
An endoscopic carpal tunnel release can be performed using local anaesthetic and you may choose to stay ‘awake’ for the surgery. This is usually done as a day procedure.
Cubital tunnel release is usually performed under a general anaesthetic and will require a one-night stay in hospital.
Ulnar nerve release from Guyon’s canal can be performed under a ‘block’ or general anaesthesia. You may choose to go home the same day (day procedure) or stay one night in hospital.
Your surgeon will discuss your diagnosis and treatment options with you in detail.
Recovery and results
Most people notice an improvement in night-time symptoms within days, although recovery times vary.
Endoscopic carpal tunnel release
Light activities can often be resumed within a few days; most return to normal function within weeks.
Cubital tunnel release
Recovery may take up to 6 weeks.
Release of the ulnar nerve from Guyon’s cana
Most return to normal function within 4-6 weeks.
You may have some tenderness, swelling or stiffness for a few weeks. Our close collaboration with Hand and Upper Limb Centre therapists means your rehab is adapted to your needs from day one.
Surgery risks
All surgery carries some risks. For carpal tunnel and nerve decompression, these may include infection, bleeding, scarring, stiffness, pain, or temporary changes in sensation. In rare cases, symptoms may persist or return over time. There are also small risks linked to anaesthesia, which your anaesthetist will discuss with you before surgery.

Frequently Asked Questions
What are carpal tunnel and cubital tunnel syndromes?
Carpal tunnel syndrome is caused by compression of the median nerve at the wrist, leading to tingling, numbness or weakness in the hand. Cubital tunnel syndrome happens when the ulnar nerve at the elbow is compressed, often causing tingling in the ring and little fingers, grip weakness, or hand clumsiness.
Do I always need surgery, and what types are available?
What are the benefits and risks of surgery?
How long does recovery take?
Recovery varies:
Endoscopic carpal tunnel release: light use often within days; many return to daily activities within weeks.
Cubital tunnel release: recovery may take longer and often involves hand therapy.
Some symptoms may improve quickly, others more gradually, and full resolution is not guaranteed depending on the degree of compression prior to surgery. Your surgeon will discuss this with you.
