Wrist Ganglia Info

Video transcript
A ganglion cyst is a smooth, fluid-filled lump that forms next to a joint or tendon, most often on the back of the wrist. It is filled with thick joint fluid that has leaked from the joint capsule and become walled off. It is not a tumour, and it is not dangerous. The lump can come and go, change size with activity, and is sometimes tender or achy, especially with wrist movement. Around half of all ganglions settle and disappear on their own over months or years. Most ganglions do not need any treatment at all. The first job is confirming the diagnosis, sometimes with an ultrasound or other imaging if anything looks unusual. If the lump is not painful and not in the way, watching and waiting is often the right call, since many resolve on their own. Drawing the fluid out with a needle can settle some, though the cyst refills in a fair proportion, because the sac and its root remain. Surgery is kept for ganglions that keep causing pain, keep coming back, or where the diagnosis is not certain. The operation removes the cyst together with its root, the small stalk connecting it to the joint, which is the part that matters for stopping it coming back. Removing the stalk brings the chance of it returning down to around five to ten percent, compared with around a third after needle drainage alone. It is a short day-surgery procedure, taking around thirty minutes, under a regional or general anaesthetic. For some ganglions on the back of the wrist, keyhole surgery is an option, which avoids a visible scar. The wound is covered with a soft dressing. You can use the hand for light tasks within days, and the dressing comes off at around one week. Heavy gripping and impact loading are held off for two to four weeks while the joint capsule heals. The wrist can feel a little tight for a few weeks as the scar softens, and this settles steadily. Most people are back to normal activity by three to four weeks. A small number of ganglions can return even after good surgery, but for most people the lump is gone for good.
Wrist ganglia are common, fluid-filled lumps – often painless – and this page covers observation, aspiration, and excision.
What you're feeling
You might notice a lump on the top or front of your wrist. If the lump is on the top, you may have pain around it. Women are more likely to feel this pain before any surgery. The pain often gets worse when you do activities that push your wrist backward, like pushing up from a chair or doing a push-up. You might find it hard to reach behind your back to fasten a bra or tuck in your shirt. Some people feel pain when they wake up in the morning or after a long day of work.
If you are a child, the lump might be on the front of your wrist. In children under 10 years old, these lumps often go away on their own. About 69% to 79% of these lumps disappear within 12 to 18 months without treatment. If the lump is on the front of your wrist, it can sometimes feel like a finger that gets stuck or clicks, similar to trigger finger.
If you have a lump on the top of your wrist, your surgeon may tell you that routine X-rays are not needed. These tests often do not show anything that changes how we treat the lump. If you have pain or the lump comes back after watching it for two months, surgery might be the next step. Surgery usually reduces your symptoms well and has a low chance of the lump returning. However, if your job or hobbies require forceful wrist movements, you might still have some pain or limited movement after surgery.
What's actually happening
A wrist ganglion is a fluid-filled sac that forms from the joint capsule, which is the sleeve of tissue surrounding your wrist joint. Think of the joint capsule like a gasket that keeps the joint lubricated. Sometimes, this gasket develops a small tear or weak spot. Fluid leaks out and collects in a balloon-like pocket under the skin. This is why you feel a lump, often on the top or palm side of your wrist.
These lumps are more common in children and women. If you have loose joints, known as wrist hyperlaxity, you are more likely to develop one. In children, these lumps often go away on their own without treatment. However, if the ganglion stays for about 2 months or causes pain, it may not resolve without help. The fluid inside can press on nearby nerves or tendons, causing discomfort or limiting your movement.
If you do heavy work that requires forceful wrist extension, you might feel pain even after the lump is treated. This is because the underlying tissue weakness can lead to residual pain or functional limits. While imaging like MRI helps your surgeon see the pain source, standard X-rays usually do not show useful details for this condition. The goal is to understand that this is a mechanical issue with the joint lining, not a bone problem or infection.
What we can do about it
For many children under 10 years old, a wrist ganglion will go away on its own. About 69% to 79% of these cysts disappear within 12 to 18 months without any treatment. Your surgeon may suggest watching the lump closely or using a splint to rest your wrist. This approach is often the first step for young patients because their bodies are very good at healing these cysts naturally.
If you are an adult, medication and injections are not always the main focus, but pain relief is important. While we do not use sclerosant injections due to safety risks like artery injury, your surgeon might discuss other options if you have pain. Note that women who feel pain before surgery are more likely to have pain remain after treatment. If you work with forceful wrist movements, be aware that you might face ongoing pain or limits in function even after care.
Surgery is considered only if the lump is painful, does not go away after about 2 months of rest, or comes back. Your surgeon will remove the cyst to reduce symptoms and lower the chance of it returning. This procedure is usually reserved for cases where simpler methods have not worked or the cyst keeps growing.
When to see someone
See your GP if you have a lump on your wrist that causes persistent pain, weakness, or instability. Ask for a specialist review if the lump locks, gives way, or stops you from sleeping or working. You should also seek help if symptoms suddenly get worse. While many lumps in children under 10 go away on their own within 12 to 18 months, you should see a doctor if pain continues after two months of rest. Your surgeon will check if the lump is affecting your daily life or if it needs treatment.
