A wrist ganglion, also known as a synovial cyst, is a fluid-filled lump that commonly appears on the back or front of the wrist. While it is generally harmless, it can sometimes cause discomfort, pain, or restricted movement. Understanding the causes, symptoms, and treatment options can help manage this condition effectively.
What Causes a Wrist Ganglion?
A wrist ganglion forms when synovial fluid, which lubricates the joints and tendons, accumulates in an abnormal capsule or sac. Though the exact cause isn’t always clear, several factors may contribute to its development:
- Repetitive Wrist Movements: Activities like typing, writing, or playing sports put stress on the wrist joint, increasing the risk of cyst formation.
- Previous Injuries: A past wrist sprain, trauma, or fracture can trigger ganglion cyst formation.
- Arthritis: Osteoarthritis or joint inflammation may contribute to the development of wrist ganglions.
- Genetic Predisposition: Some individuals may be genetically inclined to developing ganglion cysts.
Common Symptoms of a Wrist Ganglion
Ganglion cysts can vary in size and firmness, sometimes growing or shrinking over time. Symptoms may include:
✔ A visible, soft lump on the wrist
✔ Pain or discomfort, especially during wrist movement
✔ A sensation of pressure or numbness if the cyst presses on a nerve
✔ Reduced mobility in severe cases
