A wrist ganglion is a fluid-filled lump that commonly appears on the wrist and is typically benign, though it can cause discomfort or affect joint movement.
Causes: A ganglion forms when synovial fluid accumulates in an abnormal capsule. Factors include:
- Repetitive wrist use (e.g., writing, typing, sports)
- Previous wrist injuries (blows or sprains)
- Arthritis (like osteoarthritis)
- Genetics (hereditary predisposition)
Symptoms: Ganglions vary in size and may cause:
- A visible lump on the wrist
- Pain or discomfort with movement
- Pressure or numbness if pressing on a nerve
Treatments: Options depend on cyst size and symptoms:
- Observation – If no pain or mobility issues, the cyst may resolve on its own.
- Immobilization – A splint or wrist brace can prevent growth.
- Aspiration – Fluid can be drained, though recurrence is possible.
- Surgery – If pain or movement is severely affected, surgical removal is an option.
Conclusion: Though usually harmless, if a ganglion causes discomfort, treatments can help. Consult a doctor to choose the best option.
