Ganglion cysts are the most common benign lumps affecting the hand and wrist. Although harmless, they can cause pain, stiffness, weakness or concern due to their appearance, particularly when they interfere with hand function or daily activities.

At London Bridge Orthopaedics, we provide specialist assessment and treatment for ganglion cysts, offering both conservative and surgical options depending on symptoms, lifestyle and patient preference.

What is a ganglion cyst?

A ganglion cyst is a fluid-filled swelling that arises from a joint capsule or tendon sheath. The fluid inside the cyst is thick and gelatinous, similar to joint fluid, and the cyst is usually connected to the underlying joint by a narrow stalk.

Ganglion cysts most commonly occur:

• On the back or front of the wrist
• At the base of the fingers
• Near the finger joints, particularly the distal interphalangeal (DIP) joint

The size of a ganglion cyst may fluctuate over time and can sometimes increase with activity.

Who develops ganglion cysts?

Ganglion cysts can occur at any age but are most frequently seen in adults between 20 and 50 years. They are slightly more common in women than men. In many cases, there is no obvious cause.

Factors associated with ganglion cyst development include:

• Repetitive hand or wrist use
• Previous minor trauma or joint irritation
• Degenerative joint changes, particularly in finger joints
• Occupations or sports involving repeated gripping or loading

Importantly, ganglion cysts are not cancerous and do not spread.

Symptoms of a ganglion cyst

Symptoms vary depending on the size and location of the cyst. Some people experience little discomfort, while others find the symptoms significantly limiting.

Common symptoms include:

• A visible or palpable lump in the hand or finger
• Aching or sharp pain, particularly with movement or pressure
• Stiffness or reduced range of motion
• Weakness with gripping or lifting
• Tingling or numbness if nearby nerves are compressed

Pain is often activity-related and may worsen with repetitive hand use.

Aggravating factors

Symptoms may be aggravated by:

• Repetitive gripping or wrist movement
• Weight-bearing through the hands
• Prolonged use of keyboards, tools or sports equipment
• Direct pressure over the cyst

Understanding aggravating factors helps guide treatment and activity modification.

Assessment at London Bridge Orthopaedics

Assessment begins with a detailed consultation, focusing on symptom duration, functional impact, and any previous treatments. Clinical examination often provides a clear diagnosis.

Where further clarification is required, investigations may include:

• Ultrasound, to confirm the cyst and assess its origin
• MRI, in cases of diagnostic uncertainty or deep-seated cysts

Imaging also helps exclude other causes of hand lumps.

Differential diagnosis

Other conditions that may mimic a ganglion cyst include:

• Giant cell tumour of tendon sheath
• Mucous cysts
• Lipomas
• Bony swellings related to arthritis

Accurate diagnosis ensures appropriate management.

Treatment options

Conservative management

If the cyst is painless or minimally symptomatic, conservative management may be appropriate. This may include:

• Observation and reassurance
• Activity modification
• Temporary splinting in selected cases

Aspiration (drainage with a needle) may reduce the size of the cyst temporarily, but recurrence is common.

Published studies in the Journal of Bone and Joint Surgery report recurrence rates of up to 70% following aspiration alone.

Surgical treatment

Surgery is recommended when a ganglion cyst causes persistent pain, functional limitation, nerve symptoms, or recurs after aspiration.

Many patients also choose surgery for reassurance or cosmetic reasons.

The procedure involves surgical excision of the cyst, including its stalk and the portion of joint capsule or tendon sheath from which it arises.

This reduces the risk of recurrence. Surgery is usually performed as a day-case procedure, most often under local or regional anaesthetic.

Post-operatively, early movement is encouraged to prevent stiffness. Light activities can usually be resumed within one to two weeks, with full recovery over four to six weeks.

Large clinical series report recurrence rates of less than 10% following complete excision, with excellent long-term outcomes.

Recovery and long-term outlook

Most patients recover well and return to normal hand use. Complications are uncommon, particularly when surgery is performed by experienced hand surgeons.

Long-term prognosis is excellent, with durable symptom relief and restored hand function.

When to seek specialist advice

You should consider specialist assessment if:

• The lump is painful or growing
• Hand function is affected
• There is numbness or weakness
• The diagnosis is uncertain
• The cyst has returned after previous treatment

FAQs – Finger and Hand Ganglion Cysts

Do ganglion cysts need treatment?

Not always. Many can be safely observed if painless. Treatment is recommended when symptoms affect comfort or function.

Is surgery the only permanent solution?

Surgical excision offers the lowest risk of recurrence and is considered definitive treatment.

Will surgery leave a scar?

A small scar is expected, but it is usually discreet and fades over time.

How long before I can use my hand normally?

Most patients resume light use within one to two weeks, with full recovery in four to six weeks.

Can a ganglion cyst come back after surgery?

Recurrence is uncommon when the cyst and its stalk are fully removed.
