Why this operation has been suggested
Dr Kieran Hirpara, an upper-limb surgeon at Mater Private Hospital Rockhampton, starts with the least invasive options that suit your condition. Patients are generally referred to our clinic by their GP; if a physiotherapist has suggested you see us, you will still need a referral from your GP in order to be eligible for the Medicare rebate. At your appointment we take a history, examine your hand, and arrange imaging or nerve tests if they are needed. Carpal tunnel syndrome happens when a nerve in your wrist is squeezed, causing tingling, numbness and pain in your hand. We usually begin with non-operative care such as splinting, hand therapy or injections. Surgery is considered when those treatments have not given enough improvement. The operation is called a carpal tunnel release. It eases pressure on the nerve by cutting a tight band across the wrist. Significant improvements in symptom severity and hand function may be expected after this operation regardless of age, other medical conditions, or workers' compensation status. We will discuss the options with you and decide together whether surgery is right for you.
Before the operation
Your surgeon will give you clear instructions, but here is what to expect. You will need to stop eating and drinking seven hours before surgery. We ask for seven hours rather than six so you can be brought forward if the theatre list runs early. Bring a list of your current medications, and tell your surgeon about any blood thinners, as some may need to be paused beforehand. Arrange for someone to drive you home afterwards. Wear loose, comfortable clothing with sleeves that are easy to remove. Some imaging, such as an X-ray, MRI or ultrasound, may be needed to plan the operation. If you have other medical conditions, you may need blood tests or a review with the anaesthetist, but most people do not.
On the day
On the day of surgery you come to the hospital's surgical admissions unit. Staff there check you in and prepare you for theatre. You then meet the anaesthetist, the doctor who gives the anaesthetic and looks after you during the operation. This operation can be done under local anaesthetic (an injection that numbs just the area of surgery, with you awake) or under general anaesthetic (fully asleep). Most people choose local: recovery is quicker and you can go home soon after. If you'd prefer to be asleep, that's also a reasonable choice; discuss it with your surgeon and anaesthetist. You are then taken into the operating theatre, where the operation is performed. Afterwards you wake up in the recovery area, where nurses watch over you while the anaesthetic wears off. Once you are stable you either go home or spend a short time on the ward, depending on the procedure and how you are recovering.
What the operation involves
The operation is called a carpal tunnel release. Your surgeon makes a single cut over the area being operated on, at the wrist and palm. Through this cut, your surgeon reaches the tight band of tissue that forms the roof of the carpal tunnel, a narrow channel in your wrist that the nerve passes through. Cutting that band opens the tunnel and takes pressure off the nerve. The band itself does not need repairing; it heals with more room inside for the nerve.
The cut is closed with stitches. A bulky padded bandage is then wrapped around your hand and wrist. You will keep this dressing on for about 10 days, as described in the next section.
The operation itself is short, and you go home the same day. Your surgeon will explain the steps again before you sign the consent form, and you can ask questions at any point.
After the operation
You will wake up in the recovery area, where nurses watch over you while the anaesthetic wears off. Your hand will be in a bulky padded bandage, and we will give you pain relief to keep you comfortable. This is a day case, so you will go home the same day. Please arrange for someone to stay with you for the first 24 hours. We leave the dressing on for about 10 days; please do not take it off before then unless we tell you to. We change or remove it when we see you. Keep your hand raised when resting, and use it gently for light tasks as soon as you feel able. Most people are back to driving within one to two weeks, once the wound is comfortable and they can grip and turn the wheel without protecting the operated hand. See Driving after upper-limb surgery.
Recovery
For the first few days your hand will be sore and swollen, and the padded bandage will feel bulky. Keep your hand raised when you are resting, as this eases swelling and discomfort. Simple pain relief is usually enough. Many people do not need strong pain medication at all after this operation.
You will use your hand gently for light tasks as soon as you feel able. The dressing stays on until we see you, and once it is off you can wash and shower normally. Your stitches come out at your follow-up visit. Hand therapy after surgery is with Ruby Doolan at Extend Rehabilitation. Ruby will guide your exercises and make a splint if you need one for comfort. Gentle movement helps the nerve settle, so you will be using your hand more as the weeks pass.
As the swelling settles, you will notice tingling and numbness easing and your grip returning. Once you can grip and turn without pain, everyday tasks feel normal again. Timely release of the pressure on the nerve allows sensation and function in the hand to return. If your symptoms were present in both hands, we can discuss operating on both at the same visit.
Recovery varies from person to person. Your timeline may differ, and your surgeon and therapist will guide you along the way.
What can go wrong
Most patients do well, but problems can occasionally happen. Your surgeon and the team monitor you closely to spot any issue early.
Infection. A wound infection can look like redness spreading out from the cut, warmth, or oozing fluid. You might feel a deep, throbbing pain that does not ease with simple painkillers, or you might develop a fever. If you notice any of these, call the clinic the same day. If you feel unwell or the redness is spreading quickly, go to the emergency department. Some things can raise the chance of infection, such as a steroid injection into the wrist shortly before surgery or certain health conditions. We will talk through anything relevant to you before the operation.
Wound problems. Sometimes the wound edges take longer to heal or open slightly, or blood collects under the skin and causes swelling. You might see the stitches pulling apart or notice a firm, tender lump near the cut. Mention this at your follow-up visit, or call the clinic sooner if it looks worse.
Nerve irritation. The nerve being released sits close to the operating area, so it can be bruised or irritated during surgery. This usually feels like new tingling, numbness or pins and needles in the hand, or a patch of skin that feels different to before. Most nerve irritation settles with time, but some changes can last. Tell your surgeon at the next review if you notice new numbness that is not improving.
Symptoms that come back or do not fully settle. Occasionally the pressure on the nerve is not fully relieved, or the tunnel tightens again over months or years. You might notice the original tingling, numbness or night pain returning. If this happens, bring it up at your review. Further surgery is sometimes needed, and your surgeon will arrange tests to find out why.
The complications table on this page lists typical rates if you want the specifics.
When to call us
Most people recover without problems, but some signs need urgent attention. Call us if you have a fever, increasing redness or discharge from the wound, or pain that keeps getting worse. Call us if you notice new numbness in your hand that is not improving, or you cannot move your fingers. Go to emergency if you have sudden severe pain, calf swelling or pain, or shortness of breath. When in doubt, call the clinic and we will guide you.

Overview
- Symptoms of pain, numbness, and tingling in the hands are common in the general population [1].
Anatomy & Pathophysiology
Epidemiology & Symptoms
- Carpal tunnel syndrome with compression of the median nerve at the wrist is the most commonly diagnosed site of nerve compression in the upper extremity [10].
- Symptoms include paresthesia or numbness (or both) in the median nerve distribution, specifically the thumb, index finger, middle finger, and radial side of the ring finger [10].
- Nocturnal paresthesias in the radial three digits of the hand is nearly pathognomonic for carpal tunnel syndrome [10].
- Paresthesias occur characteristically in "fixed wrist activities" such as reading a book or a newspaper, driving, or use of a computer keyboard or mouse [10].
- Patients rarely describe aching in the thenar eminence [10].
- With advanced nerve compression, weakness and atrophy of the abductor pollicis brevis and opponens pollicis muscles occur [10].
- Because of the slow onset of thenar weakness, patients typically adapt to this loss without functional impairments [10].

Anatomical Structures & Surgical Landmarks
- The palmar cutaneous sensory branch of the median nerve lies in the interval between the palmaris longus and the flexor carpi radialis tendons [4].
- The palmar cutaneous branch of the median nerve is located deep to the thenar crease and radial to the palmaris longus [11].
- The superficial palmar arterial arch is 5 to 8 mm distal to the distal margin of the transverse carpal ligament [4].
- The flexor retinaculum includes the distal deep fascia of the forearm proximally, the transverse carpal ligament, and the aponeurosis between the thenar and hypothenar muscles [4].
- Fibers of the transverse carpal ligament can extend distally farther than expected [4].
- The recurrent branch of the median nerve may perforate the transverse carpal ligament and leave the median nerve on the volar side [4].
- Potential anatomical anomalies include connections between the flexor pollicis longus and the index flexor digitorum profundus tendons [4].
- Potential anatomical anomalies include anomalous flexor digitorum superficialis [4].
- Potential anatomical anomalies include palmaris longus, hypothenar, and lumbrical muscle bellies [4].
- Potential anatomical anomalies include median and ulnar nerve branches and interconnections [4].
- The thenar crease takes a variable course [4].
- A crossing cutaneous branch from the ulnar nerve is identified in a distal portion of the incision about 15% of the time [11].
Diagnostic & Prognostic Factors
- Carpal tunnel syndrome is a clinical diagnosis based on a combination of symptoms and characteristic physical findings [10].
- Electrodiagnostic studies are useful to stage the degree of nerve compression and assist in anticipating the time needed for recovery of nerve function [10].
- Patients with long-standing symptoms, severe atrophy of the thenar musculature, and dense sensory loss should be cautioned that release may not lead to complete recovery of sensation or thenar strength [10].
- Ultrasound sensitivity for carpal tunnel syndrome has been reported to be over 97% when the median nerve diameter is greater than 10 mm² at the level of the pisiform [5].
- In patients with negative electrodiagnostic studies but a clinical diagnosis of carpal tunnel syndrome, high-resolution ultrasonography has a sensitivity of 73% if the cutoff of 9.4 mm² at the inlet of the carpal tunnel is used [5].
- The diagnosis of carpal tunnel syndrome should be based on clinical acumen and physical examination in the vast majority of patients [5].
- Ancillary tests should be reserved for patients without clear presentations [5].
- MRI is not routinely used for diagnosis of carpal tunnel syndrome [5].
- A major advantage of MRI is its high soft-tissue contrast, which gives detailed images of bones and soft tissues [5].
- Reported false-negative rates of electrodiagnostic testing are 10% [5].
- Postoperative electrodiagnostic testing may be helpful in assessing recurrent symptoms [5].
Clinical Presentation
Epidemiology and Risk Factors
- Carpal tunnel syndrome is the most common compression neuropathy of the upper extremity [9].
- The mean age at diagnosis for carpal tunnel syndrome is 50 years [9].
- Carpal tunnel syndrome is more common in women than men by nearly four times [9].
- By the age of 65 years, the prevalence of carpal tunnel syndrome is approximately 5.1% for women and 1.3% for men [9].
- Risk factors for carpal tunnel syndrome include obesity, pregnancy, hypothyroidism, diabetes mellitus, and menopause [9].
- The American Academy of Orthopaedic Surgeons guidelines list body mass index (BMI) and high hand repetition rate as factors with strong evidence of increased risk for development of carpal tunnel syndrome [9].
Clinical Symptoms and Signs
- Classically, carpal tunnel syndrome presents with nocturnal paresthesias in a median nerve distribution that gradually worsen as nerve injury progresses [9].
- Late in the disease course, carpal tunnel syndrome leads to sensory loss and thenar muscle atrophy [9].
- Many patients report pain in the hand and may report symptoms that are not directly referable to the median nerve [9].
- A positive Tinel sign at the wrist can aid in the diagnosis of carpal tunnel syndrome [9].
- Development of symptoms after a provocative Phalen maneuver can aid in the diagnosis of carpal tunnel syndrome [9].
- The reported specificity of the Tinel sign at the wrist varies from 55% to 100% [9].
- The reported specificity of the Phalen test varies from 54% to 98% [9].
- Tinel sign and Phalen maneuver are most reliable as adjuncts to other diagnostic tests [9].
Diagnostic Testing
- Nerve conduction studies are a useful diagnostic tool for carpal tunnel syndrome, assessing focal demyelination by delayed conduction velocities of the median nerve at the wrist [9].
- Needle electromyography is considered an optional adjunct to nerve conduction studies and is mostly used to differentiate carpal tunnel syndrome from other possible causes [9].
- Documenting muscle atrophy and fibrillations on needle EMG can assist with identifying severity of the disease and help with prognostication [9].
- Thenar atrophy and abductor pollicis brevis weakness can often be detected on physical examination [9].
- Ultrasonography allows rapid diagnosis of carpal tunnel syndrome by identification of enlarged, hypoechoic median nerve fascicles proximal to the carpal tunnel [9].
- Controversy remains as to whether ultrasonography evaluation could replace electrophysiology in the diagnosis of carpal tunnel syndrome [9].
- MRI and/or ultrasonography imaging should be considered in patients who have new, persistent, or recurrent symptoms after surgery to delineate the etiology of the symptoms [9].
- Ancillary tests for carpal tunnel syndrome should be reserved for patients without clear presentations [5].
- Reports of MRI in carpal tunnel syndrome are promising, especially with newer techniques such as diffusion tensor imaging [5].

Diagnostic Principles
- The diagnosis of carpal tunnel syndrome is made by clinical history, physical examination, and supportive diagnostic testing with exclusion of other possible disorders [9].
Treatment
Operative Technique
- Palmar incisions for carpal tunnel release should be placed well ulnar to the thenar crease to avoid injury to the median nerve palmar cutaneous branch [4].
- A curved incision ulnar and parallel to the thenar crease is not advisable because the palmar cutaneous branch of the median nerve may be at higher risk of injury proximally [4].
- The incision should be extended proximally to the wrist flexion crease and angled toward the ulnar side of the wrist to avoid crossing flexor creases at a right angle [4].
- The palmar cutaneous sensory branch lies in the interval between the palmaris longus and the flexor carpi radialis tendons [4].
- If the palmar sensory branch is severed, it frequently causes a painful neuroma that may later require excision from the scar [4].
- When the palmar sensory branch is severed, repair is not attempted; instead, the nerve is sectioned more proximally to be covered by the middle finger sublimis muscle [4].
- The transverse carpal ligament (TCL) must be carefully divided while avoiding damage to the median nerve and its recurrent branch, which may perforate the ligament and leave the median nerve on the volar side [4].
- Fibers of the TCL can extend distally farther than expected [4].
- The flexor retinaculum includes the distal deep fascia of the forearm proximally, the TCL, and the aponeurosis between the thenar and hypothenar muscles [4].
- A successful carpal tunnel release usually requires division of all components of the flexor retinaculum [4].
- Potential anatomical anomalies to be aware of include connections between the flexor pollicis longus and index flexor digitorum profundus tendons, anomalous flexor digitorum superficialis, palmaris longus/hypothenar/lumbrical muscle bellies, and median/ulnar nerve branches and interconnections [4].
- The superficial palmar arterial arch is located 5 to 8 mm distal to the distal margin of the TCL and must be avoided [4].
- Tenosynovectomy is occasionally indicated, especially in patients with rheumatoid arthritis [4].
- Closure involves only the skin, with wound drainage as needed [4].
Postoperative Care
- A light compression dressing and a volar splint may be applied postoperatively [4].
- The hand is actively used as soon as possible after surgery, but the dependent position is avoided [4].
- The dressing can usually be removed by the patient at home 2 or 3 days after surgery [4].
- Gentle washing and showering of the hand are permitted after dressing removal [4].
- Gradual resumption of normal hand use is encouraged [4].
- Sutures are removed after 10 to 14 days [4].
- A splint may be continued for comfort as needed for 14 to 21 days [4].
Complications
- Transection of the motor branch of the ulnar nerve is a complication of two-portal endoscopic carpal tunnel release [2].
- Scar discomfort can occur after carpal tunnel surgery [2].
- Recurrent carpal tunnel syndrome is a recognized clinical entity following carpal tunnel release [2].
- Poor outcome is associated with neural surgery (epineurotomy or neurolysis) for carpal tunnel syndrome compared with carpal tunnel release alone [2].
- Symptoms may return after carpal tunnel surgery [2].
- Complications related to carpal tunnel release are a documented clinical concern [2].
- Carpal tunnel release in patients with diabetes results in poor outcomes in long-term study [3].
