Carpal Tunnel Release Surgery in Melbourne
Carpal tunnel release surgery relieves pressure on the median nerve in the wrist by dividing the transverse carpal ligament, the tight band of tissue that forms the roof of the carpal tunnel.
It is the most commonly performed hand surgery in Australia and is used to treat carpal tunnel syndrome, a condition that causes numbness, tingling, weakness, and pain in the thumb, index, middle, and ring fingers.
At Specialist Surgical Group, our Melbourne-based hand surgeons perform carpal tunnel release as a day procedure under local anaesthetic, typically taking 20-30 minutes. Surgery may be performed using an open or endoscopic technique, and the most appropriate approach is determined at your consultation.
Left untreated, persistent median nerve compression can cause permanent weakness and sensory loss, making timely assessment important.
We consult from our Essendon and Bundoora clinics, with procedures performed at accredited hospitals in Melbourne.

What is carpal tunnel syndrome?
Carpal tunnel syndrome is a common condition caused by compression of the median nerve as it passes through the carpal tunnel, a narrow passageway of bones and ligaments at the base of the wrist. The median nerve controls sensation in the thumb, index finger, middle finger, and part of the ring finger, as well as movement in the small muscles at the base of the thumb.
When the tissues surrounding the flexor tendons in the wrist swell, they reduce the space available for the median nerve, placing it under pressure. This typically produces tingling, numbness, and pain in the affected fingers, symptoms that are often worse at night or after repetitive hand movements. In more advanced cases, patients may notice weakness when gripping objects or a gradual wasting of the thenar muscle at the base of the thumb.
Carpal tunnel syndrome is the most frequently diagnosed nerve compression disorder of the upper limb in Australia, affecting people across a wide range of occupations and activity levels. While mild cases may respond to conservative management, such as wrist splinting or corticosteroid injections, surgical release is recommended when symptoms persist or progress, or when nerve conduction studies confirm significant median nerve impairment.
Do you need surgery?
Carpal tunnel release surgery may be appropriate for you if:
- You have confirmed carpal tunnel syndrome on nerve conduction studies, showing median nerve compression
- You experience persistent or worsening numbness, tingling, or pain in your thumb, index, middle, or ring fingers
- Nocturnal symptoms are disrupting your sleep despite the use of a wrist splint
- Steroid injections have provided only temporary or insufficient relief
- You have developed weakness or wasting of the thenar muscles (the fleshy pad at the base of your thumb)
- Your symptoms are significantly affecting your ability to work, perform daily tasks, or maintain grip strength
- Conservative treatment, including splinting, activity modification, and physiotherapy, has not produced adequate improvement
During your initial consultation, your surgeon will review your symptoms, nerve conduction study results, and medical history to confirm the diagnosis and determine whether surgical release is the most appropriate next step.
Potential benefits
- Reliable symptom relief. Carpal tunnel release is one of the most effective surgical interventions in hand surgery. Studies consistently report that more than 90% of patients experience significant improvement in numbness, tingling, and pain following surgical release [1].
- Resolution of nocturnal symptoms. Night-time tingling and pain, which often disrupt sleep, typically resolve promptly after surgery, with most patients reporting improved sleep quality within the first few weeks [2].
- Prevention of permanent nerve damage. Timely surgery halts ongoing compression before irreversible changes occur in the median nerve. Patients treated before significant thenar wasting develops generally achieve better functional outcomes than those who delay [3].
- Restoration of grip and pinch strength. Most patients experience meaningful recovery of hand strength and fine motor control within 3 months of surgery, enabling a return to work and activities that require gripping or pinching [1].
- Superior long-term outcomes compared to non-surgical treatment. A Cochrane systematic review found that surgical treatment produces significantly better outcomes than splinting at 12 months, with lower rates of symptom recurrence and less need for further intervention [4].
- Durable results. The recurrence rate following carpal tunnel release is low, estimated at less than 5% over 5 years, making it a long-term solution for the majority of patients [5].
Potential risks
- Pillar pain. A deep aching discomfort in the palm on either side of the surgical scar, known as pillar pain, affects a proportion of patients in the weeks following open carpal tunnel release. It typically resolves within 2-4 months, but can temporarily limit grip strength and return to manual work [6].
- Incomplete symptom resolution. Patients with longstanding or severe nerve compression, significant thenar wasting, or advanced changes on nerve conduction studies may not achieve full resolution of symptoms, particularly permanent numbness or weakness that was present before surgery [3].
- Scar tenderness. The surgical incision in the palm can remain sensitive to pressure for several months. Desensitisation exercises and scar massage are typically recommended to manage this during recovery [6].
- Infection. Wound infection occurs in approximately 1-2% of carpal tunnel release procedures. The risk is minimised by sterile technique and, where indicated, prophylactic antibiotics [7].
- Nerve or vessel injury. Injury to the median nerve, its palmar cutaneous branch, or the superficial palmar arch is rare but recognised. The risk is higher in revision procedures or cases with atypical anatomy, which your surgeon will assess before recommending a surgical approach [8].
- Symptom recurrence. While uncommon, carpal tunnel syndrome can recur following surgical release due to scar tissue formation around the nerve or incomplete division of the ligament. Recurrence rates are estimated at less than 5% at 5 years [5].

Carpal tunnel release surgery journey
The following steps provide a brief overview of your carpal tunnel release surgery journey. Individual experiences will vary based on your specific health circumstances.
1. Initial consultation
We will review your symptoms, the results of your nerve conduction studies, and your medical history.
A clinical examination of your wrist and hand will assess sensation, thenar muscle bulk, grip strength, and provocative signs such as Tinel’s sign and Phalen’s test.
We will discuss surgical options, including open and endoscopic techniques, and receive clear information about what to expect before, during, and after the procedure.
2. Pre-operative preparation
You will receive specific instructions regarding fasting before surgery, medications to pause or continue, and what to arrange for your recovery at home.
If you take blood thinners or anti-inflammatory medications, we will advise you when to stop them.
Because the procedure is performed under local anaesthetic or local anaesthetic with light sedation in most cases, you may not require an overnight stay.
3. The carpal tunnel release procedure
Carpal tunnel release is performed under local anaesthetic at an accredited Melbourne hospital or day procedure centre, and typically takes 20-30 minutes.
For an open release, a small incision of approximately 3-4 cm is made in the palm of the hand. We identify and carefully divide the transverse carpal ligament under direct vision, creating more space for the median nerve. The wound is then closed with sutures, and a bulky dressing is applied to protect the palm.
For an endoscopic release, a smaller wrist incision is used, and the ligament is divided with a small camera, which may allow a slightly faster return to hand use for some patients.
We will discuss which approach is most appropriate for your anatomy and circumstances.
4. Recovery room and discharge
Most patients can move their fingers immediately after surgery and notice early improvement in tingling.
You will be monitored briefly in recovery before being discharged home the same day, typically within 1-2 hours of the procedure.
You will need a responsible adult to drive you home. Pain is usually mild and well-controlled with simple over-the-counter analgesics.
5. Wound care
Keep the hand elevated when resting to minimise swelling. The dressing will be reviewed at your first follow-up appointment, and the sutures will be removed approximately 10-14 days later.
During this period, avoid firm gripping, lifting, and immersing the hand in water. Gentle finger and wrist exercises will be provided to prevent stiffness.
6. Return to activity and follow-up
Once the wound has healed, activity can be progressively resumed. Most patients return to desk-based work within 2 weeks.
Those with physically demanding or manual jobs typically require 4-6 weeks before resuming full duties. Grip strength and sensation generally continue to improve for 3-6 months, with some patients noticing ongoing gains for up to 12 months if nerve compression was significant prior to surgery.
A follow-up appointment is scheduled at 6-8 weeks to assess recovery, with further review arranged as needed.

The procedure itself typically takes 20-30 minutes, including preparation and time in the recovery room. Most patients spend approximately 2-3 hours at the clinic or hospital. Carpal tunnel release is performed as a day procedure, so no overnight hospital stay is required in the vast majority of cases.
Both approaches divide the transverse carpal ligament and achieve equivalent clinical outcomes in terms of symptom relief. Open release provides direct visualisation of the structures being divided and is the more commonly performed technique.
Endoscopic release uses a smaller incision and a camera, which may reduce early post-operative scar discomfort and allow a slightly faster return to some activities. However, endoscopic release carries a marginally higher risk of incomplete ligament division or nerve injury in technically challenging cases [8].
We will recommend the most appropriate approach based on your specific anatomy and history.
Most patients can use their hand for light activities such as typing and writing within a few days, and return to desk work within 1-2 weeks. Manual labourers and those with physically demanding jobs generally require 4-6 weeks before returning to full duties. Grip strength and sensation typically continue to recover for 3-6 months, and in some cases up to 12 months.
Carpal tunnel release is a Medicare-listed procedure when performed for confirmed carpal tunnel syndrome. Patients with private hospital-level health insurance will generally have the main hospital and theatre costs covered, subject to their policy’s excess and any applicable waiting periods. Out-of-pocket costs vary depending on your insurer, anaesthetist, and facility, but typically range from $500 to $2,500 for patients with appropriate private health cover. We will provide a detailed fee estimate at your consultation, and we recommend contacting your insurer before booking to confirm your cover. Uninsured patients can discuss self-funded options with our team.
For mild to moderate carpal tunnel syndrome, non-surgical treatments such as wrist splinting and steroid injections can provide meaningful relief, though symptoms often return over time. For patients with moderate to severe compression on nerve conduction studies, or with thenar weakness and muscle wasting, delaying surgery increases the risk of permanent nerve damage that may not fully recover even after a technically successful operation. Your surgeon will advise you on the urgency of treatment based on your specific findings.
The recurrence rate following carpal tunnel release is low, generally less than 5% at 5 years. In the small number of cases where symptoms do recur, they are usually milder than the original presentation and may be managed non-surgically. Recurrence is more likely in patients with underlying conditions such as diabetes, hypothyroidism, or rheumatoid arthritis, where treating the underlying condition is also important.
We typically recommend treating one hand at a time to ensure proper healing and maintain functional independence during recovery. The second hand can usually be treated 6-8 weeks after the first procedure.
Most patients do not require formal hand therapy following an uncomplicated carpal tunnel release. Your surgeon will provide a home exercise programme to prevent stiffness and assist recovery. In cases where grip strength is significantly reduced, where there was thenar wasting before surgery, or where recovery is slower than expected, a referral to a hand therapist will be arranged.
Steroid injections into the carpal tunnel can provide effective short-term relief, often lasting several months. However, their benefit tends to diminish with repeated use, and they do not address the underlying structural compression. For patients with moderate to severe CTS, or those who have had temporary relief from injections but experienced recurrence, surgical release consistently produces better long-term outcomes [4]. Injections remain a reasonable first-line option for mild cases, during pregnancy, or when surgery needs to be delayed.
