A wrist ganglion, or synovial cyst, is a fluid-filled lump often seen on the back or front of the wrist. It’s a harmless condition, but it can cause discomfort or affect joint movement.
A wrist ganglion forms when synovial fluid, which lubricates joints and tendons, builds up in an abnormal capsule or bursa. While the cause isn’t always clear, some factors might play a role:
- Repetitive Wrist Use: Activities like writing, typing, or playing sports can stress the joint.
- Past Injuries: A wrist blow or sprain can lead to the cyst’s formation.
- Arthritis: In some cases, osteoarthritis may be related to ganglion appearance.
- Genetic Factors: Some people are genetically more likely to develop these cysts.
Synovial cysts come in different sizes and can change over time. Symptoms include:
- A visible, soft lump on the wrist.
- Pain or discomfort when moving the joint.
- Pressure or numbness if the ganglion presses on a nerve.
Treatment depends on the cyst’s size and if it causes pain or limits movement. Options are:
- Observation: If the ganglion isn’t painful or affecting movement, doctors often suggest just watching to see if it goes away on its own.
- Immobilization: Wearing a splint or wrist brace can reduce joint pressure and stop the cyst from growing.
- Aspiration: A doctor can use a needle to drain the fluid, but the cyst might come back.
- Surgery: If the ganglion causes severe pain or limits movement, it can be removed surgically, which has a lower recurrence risk.
A wrist ganglion is a harmless condition, but if it causes discomfort, there are treatments. It’s important to consult a doctor to find the best solution for each case.
