Ganglion Cysts: Causes, Risk Factors, and Prevention

A ganglion cyst is a fluid-filled sac that develops on the back of the wrist or hand. It arises from a weakness in the joint capsule or tendon sheath, allowing synovial fluid to leak out and form a cyst.

Risk Factors

• Repetitive motion: Activities involving repetitive wrist/hand movements (typing, writing, playing instruments) increase risk.
• Wrist injury: Previous sprain or fracture can lead to cyst formation.
• Certain medical conditions: Osteoarthritis and rheumatoid arthritis elevate risk.

Symptoms & Treatment

Ganglion cysts are often painless but can cause discomfort or limit movement. Treatment options for symptomatic cysts include aspiration, surgery, or corticosteroid injections.
