Hand Surgery (Carpal Tunnel Release, Dorsum Ganglion Surgery)

Carpal Tunnel Release & Dorsal Wrist Ganglion Surgery (First Presentation)

This page explains two common hand/wrist conditions that may need surgical treatment in first presentations (not recurrent cases):

1. Carpal Tunnel Syndrome (CTS)  sometimes treated with Carpal Tunnel Release
2. Dorsal Wrist Ganglion  sometimes treated with Dorsal Ganglion Excision

The goals are to confirm the diagnosis, rule out other causes, start appropriate non-surgical management, and proceed to surgery only when it is clearly beneficial.

1) Carpal Tunnel Syndrome (CTS)

What is it?

Carpal tunnel syndrome happens when the median nerve is compressed at the wrist inside a narrow tunnel (the “carpal tunnel”). This can cause numbness, tingling, pain, and weakness, especially in the thumb, index, middle, and half of the ring finger.

Typical first presentation

Most patients describe:

• Numbness/tingling in the thumb–index–middle fingers
• Symptoms worse at night or with driving/phone use
• Hand clumsiness (dropping objects)
• Sometimes weakness or wasting of the thumb muscles in advanced cases

Common risk factors

• Repetitive wrist use (work, hobbies)
• Pregnancy
• Diabetes
• Thyroid disease
• Inflammatory arthritis
• Previous wrist injury

Assessment in the clinic

Your appointment typically focuses on:

• A detailed symptom history (pattern, duration, triggers)
• Examination of sensation, strength, and thumb function
• Specific bedside tests (provocation tests) to support the diagnosis
• Checking for other diagnoses that can mimic CTS (neck nerve irritation, ulnar nerve problems, tendon issues)

Investigations

Nerve Conduction Studies (NCS) – strongly recommended

For many patients, NCS (often with EMG) helps:

• Confirm CTS and grade severity
• Identify other nerve problems (e.g., cervical radiculopathy, ulnar neuropathy)
• Support decision-making when surgery is being considered

Referral tip: Ideally, your referral should include NCS results (or a request for NCS) if carpal tunnel syndrome is suspected, especially if symptoms are moderate/severe, long-standing, or there are any weakness signs.

Additional tests that may be required

Depending on symptoms and examination, other tests can be helpful:

• Blood tests (e.g., diabetes, thyroid function) if clinically relevant
• X-ray (if there’s trauma history, arthritis symptoms, or atypical pain)
• Ultrasound (sometimes useful to assess median nerve swelling or space-occupying lesions, or to role out other pathology)

Treatment options (first presentation)

Non-surgical treatment (often first line)

Appropriate when symptoms are mild to moderate and there’s no significant weakness:

• Night splinting in neutral wrist position
• Activity modification and ergonomic changes
• Anti-inflammatory measures if appropriate
• Steroid injection (in selected patients) to reduce inflammation and confirm diagnosis
• Managing contributing conditions (e.g., diabetes, thyroid disease)

When is surgery considered?

Carpal tunnel release may be recommended when:

• Symptoms persist despite a reasonable trial of non-surgical therapy
• NCS shows moderate to severe compression
• There is weakness, reduced thumb function, or muscle wasting
• Symptoms significantly affect sleep, work, or daily function
• There are frequent or progressive symptoms suggesting nerve compromise

Carpal Tunnel Release Surgery

What does the surgery do?

Carpal tunnel release involves cutting the tight band (transverse carpal ligament) that is compressing the median nerve. This creates more space for the nerve and tendons.

How it’s typically performed

• Usually a day procedure
• In our practice is done under general anaesthetic
• An incision in the palm/wrist area
• The ligament is released, wound closed, and a dressing applied

Expected recovery

• Numbness/tingling often improves early, but may take weeks to months depending on severity and duration
• Grip strength can take time to return
• Soreness around the scar/pillar pain can occur temporarily
• Return to light activity is usually earlier; heavy lifting/manual work can take longer

2) Dorsal Wrist Ganglion

What is it?

A dorsal wrist ganglion is a benign fluid-filled cyst that typically arises from the wrist joint capsule or tendon sheath. It often appears as a lump on the back (dorsum) of the wrist/hand.

This page focuses only on:

• Dorsal wrist ganglion
• First presentation (not recurrence)

Typical first presentation

Patients may notice:

• A visible lump that changes in size
• Aching discomfort (especially with wrist extension, push-ups, lifting)
• Occasionally reduced wrist range of motion
• Sometimes no pain, but concern about appearance

Investigations

Often, the diagnosis is clinical. Your surgeon may request:

• X-ray to look for underlying arthritis or bony issues (especially if pain is prominent)
• Ultrasound to confirm a ganglion and distinguish it from other lumps
• MRI in selected cases when the diagnosis is uncertain or symptoms are atypical

Treatment options (first presentation)

Non-surgical management

Appropriate when symptoms are mild:

• Observation (many ganglions fluctuate and can settle)
• Activity modification
• Splinting in selected cases
• Aspiration (drainage) may be considered in some patients, but recurrence can occur. In our practice we do not offer aspiration (can be done by the referring doctor or another clinician) and if the above management fails then we offer surgery.

When is surgery considered?

Dorsal ganglion surgery may be recommended when:

• Ongoing pain affecting function or work
• Persistent lump with significant symptoms
• Diagnostic uncertainty or concern about alternative pathology (after assessment/imaging)
• Patient preference after discussing risks, benefits, and recurrence rates

Dorsal Ganglion Excision Surgery

What the surgery involves

• Removal of the ganglion cyst and its stalk/connection to the joint capsule
• Usually a day procedure
• Performed with regional/local anaesthetic ± sedation or general anaesthetic depending on patient and setting
• Dressing/splint may be used for a short period post-operatively

Recovery expectations

• Temporary stiffness is common early
• Gradual return to wrist loading and sports as comfort and strength improve
• Some tenderness around the scar can occur
• Recurrence is possible even after surgery, but the aim is to reduce symptoms and recurrence risk

Risks and complications (important for both procedures)

All surgery carries some risk. Your surgeon will discuss what is most relevant to your condition and health factors.

General risks

• Anaesthetics risks
• Bleeding or haematoma
• Infection
• Pain and swelling
• Scarring or scar sensitivity
• Stiffness and reduced range of motion (more relevant for ganglion surgery)
• Need for further treatment or therapy

Nerve injury (key risk)

Because hand and wrist surgery occurs near important nerves, there is a specific risk of nerve injury, including:

Sensory nerve injury

• Numbness or altered sensation in parts of the hand/fingers
• Painful neuroma (sensitive nerve scar) in rare cases

Motor nerve injury

• Weakness in thumb function (for CTS, median nerve motor branch risk)
• Reduced grip or pinch strength beyond expected recovery (rare)
• Material risk ( can compromise your hand function, work, daily activities etc)

Procedure-specific considerations

Carpal Tunnel Release

• Incomplete symptom relief if nerve compression is long-standing or severe
• Persistent or temporary “pillar pain” around the heel of the palm
• Temporary flare of symptoms during nerve recovery
• Very rarely, significant median nerve injury

Dorsal Ganglion Excision

• Recurrence of the ganglion
• Wrist stiffness or prolonged discomfort during loading
• Irritation of nearby sensory branches causing numbness/tingling

What to include in your referral (helps speed up care)

For suspected Carpal Tunnel Syndrome, your referral ideally includes:

• Symptom duration, severity, and functional impact
• Examination findings (sensory changes, weakness, thenar wasting if present)
• Any relevant medical history (diabetes, thyroid disease, pregnancy, inflammatory arthritis, trauma)
• NCS/EMG results if already done (or request to obtain them)
• Previous treatments tried (splint, injection, therapy)

For Dorsal Wrist Ganglion, your referral ideally includes:

• Location confirmed as dorsal (back of wrist/hand)
• Duration, pain level, functional impact, size changes
• Any prior imaging (x-ray/ultrasound) if performed
• Confirmation this is first presentation (not recurrence)

Summary

Carpal Tunnel Syndrome is a common nerve compression condition often confirmed with Nerve Conduction Studies (NCS), which helps guide treatment and surgical decision-making. Carpal Tunnel Release is considered when symptoms persist, are severe, or there is objective nerve compromise.

Dorsal Wrist Ganglion is usually a benign cyst on the back of the wrist. Many can be observed, but surgery may be appropriate when pain or functional limitation persists, or when imaging/assessment supports excision for first presentations.

Both operations are typically day procedures, aiming for symptom relief and return of function, but they carry risks, particularly sensory and motor nerve injury, along with infection, bleeding, stiffness, scarring, and the possibility of incomplete relief or recurrence depending on the condition.
