Ganglion Cysts: Pathophysiology, Clinical Presentation, and Contemporary Management in Orthopedic Practice

Ganglion cysts represent the most common soft tissue tumors of the hand and wrist, accounting for approximately 50–70% of all such lesions in this region. Despite their benign nature, ganglions may cause significant patient concern due to pain, compression of nearby structures, and functional limitation. These mucin-filled lesions are typically connected to the underlying joint capsule or tendon sheath via a stalk, which serves as a one-way valve, allowing fluid accumulation but not drainage.

In clinical orthopedics, ganglion cysts are a frequent presentation, particularly in young adults and middle-aged women. Accurate diagnosis and patient-specific treatment planning are key to optimizing outcomes, particularly in high-functioning individuals, manual laborers, or those with cosmetic concerns.

Pathogenesis and Risk Factors

The exact etiology of ganglion cysts remains unclear, though several theories propose a degenerative or traumatic origin.

Proposed Mechanisms:

• Myxoid degeneration of connective tissue

• Synovial herniation from increased intra-articular pressure

• Mucin overproduction by mesenchymal cells lining the joint capsule

Risk factors include:

• Repetitive microtrauma or wrist overuse

• Occupations involving frequent wrist extension (e.g., typing, gymnastics, mechanics)

• History of joint instability or prior tendon injury

Common anatomical locations include:

• Dorsal wrist (scapholunate joint) – most prevalent

• Volar wrist (radiocarpal joint)

• Finger flexor tendon sheaths (mucous cysts)

• Foot dorsum or ankle (less common)

Clinical Features and Symptoms

Ganglion cysts often present as soft, fluctuant, non-tender masses near a joint or tendon. Their size may fluctuate and can become painful due to compression of adjacent structures, such as nerves or tendons.

Common symptoms include:

• Visible swelling, often round or oval in shape

• Localized aching or pain exacerbated by movement

• Reduced joint mobility (in large or deep ganglia)

• Numbness or tingling if compressing adjacent nerves (e.g., radial or ulnar nerve branches)

While some ganglia are asymptomatic and discovered incidentally, others significantly impact functional performance—especially in athletes, musicians, or manual workers.

Diagnostic Evaluation

Diagnosis is primarily clinical, supported by imaging in ambiguous or deep-seated cases.

• Transillumination Test: Simple, in-office confirmation of cystic nature

• Ultrasound: Useful for determining cyst size, location, and internal characteristics

• MRI: Gold standard for evaluating deep or occult ganglions, especially intraosseous or intratendinous variants

• Radiographs: Rule out bony pathology or degenerative changes

Differential diagnosis includes lipoma, synovial sarcoma, epidermoid cyst, and tenosynovitis, particularly in atypical presentations.

Treatment Modalities

Management of ganglion cysts can be conservative or surgical, depending on symptom severity, functional impairment, and recurrence risk.

Non-Surgical Treatment

1. Observation: Asymptomatic ganglions often resolve spontaneously.

2. Immobilization: Wrist splints may reduce cyst size and pain during activities.

3. Aspiration: In-office procedure using a needle and syringe. Often paired with corticosteroid injection, though recurrence rates approach 50–70%.

Surgical Management

Indicated for:

• Recurrence after aspiration

• Persistent pain or neurologic symptoms

• Cosmetic concerns in high-demand patients

Excision Techniques:

Proper identification and removal of the stalk is essential to minimize recurrence.

• Arthroscopic ganglionectomy: Minimally invasive, less postoperative pain, lower recurrence rates.

• Open excision: Complete cyst and stalk removal; recurrence ~5–15%.

Postoperative Care and Prognosis

• Recovery time: 2–6 weeks depending on procedure and occupation.

• Physical therapy may be recommended to restore motion and strength.

• Recurrence is possible even after surgical excision, but significantly lower than with aspiration alone.

• Complications (rare): Scar tenderness, neurovascular injury, infection.
