A wrist ganglion, or synovial cyst, is a non-cancerous, fluid-filled lump that usually forms on the front or back of the wrist. While harmless, it can cause discomfort or restrict movement.
What Causes It?
Ganglions form when joint-lubricating synovial fluid collects in a sac. Though the exact cause isn’t always clear, common triggers include:
-
Repetitive wrist use (typing, sports)
-
Past wrist injuries or sprains
-
Arthritis
-
Genetic predisposition
Symptoms
-
Soft, visible lump
-
Pain or discomfort with movement
-
Pressure or numbness if a nerve is compressed
Treatment Options
-
Observation: If painless, it may go away on its own.
-
Immobilization: Braces or splints reduce joint stress.
-
Aspiration: Fluid removal via needle, though recurrence is common.
-
Surgery: Used for painful or persistent cysts, with lower recurrence risk.
