Ganglion
A lump filled with joint fluid — almost always benign and often needing no treatment.
Also known as: ganglion cyst · wrist lump · bump on the wrist · tendon nodule

A small firm or tense ball at the wrist is usually harmless. The most common cause is a ganglion cyst — a pouch of joint fluid arising from a joint capsule or tendon sheath. It waxes and wanes, sometimes vanishes, and mainly bothers with certain movements or on pressure. If there was a fracture here, the lump can also be the callus: the bony thickening a fracture heals with — normal healing, not a tumour. The calm core: almost all these lumps are benign. But since a fracture came first and it hinders sport, a medical look is worth it, ideally in hand surgery — usually X-ray (bone/callus) and ultrasound (ganglion).
During sport a wrist support relieves pressure on the lump. Temporarily ease movements that pull or press hard.
Don’t press, knead or hit it — irritation tends to make it worse.
Targeted exercises and manual therapy can improve mobility and strength, especially after a fracture.
Ganglions fluctuate on their own, a callus remodels over months. Note any change and show it at the appointment.
About one in fifty people has one; most often between twenty and forty, women three times as often. Up to half disappear by themselves within a few years without any treatment. After draining, it returns in about half to two thirds within a year; after surgery in about one in ten. The size varies with use — it grows with hand work and shrinks at rest.
No treatment makes a ganglion recede. What used to be usual — hitting it with a book — bursts the capsule and brings it back in most people within months, with the risk of injuring tendons and nerves. Draining it empties the jelly; in half to two thirds it refills within a year. Only surgery also removes the stalk to the joint — there it returns in about one in ten.
The commonest cause: a benign, fluid-filled cyst. It can be watched; if it really bothers, it can be aspirated or removed surgically — both can recur.
A fracture heals via a callus — a bony thickening at the break. It feels hard and firm and largely remodels over months. An X-ray shows it clearly.
Sometimes a small nodule sits on a tendon or its sheath and rubs with movement. Hand therapy and graded load often help.
With pain, rapid growth, numbness or tingling in the fingers (nerve) or — as here — after a fracture: please have it checked, ideally in hand surgery, with X-ray and/or ultrasound.
The old habit of hitting a ganglion with a book to burst it is no longer advised: it hurts, can injure, and the lump often returns.
A hard lump near a joint can also be a gout tophus — uric acid is the value for that.
With several nodules on fingers or elbows, rheumatoid factor is measured as well.
Without vitamin D only a fraction of the calcium from food is taken up. It is the value that is most often too low with bone and joint complaints.
The building material itself. Better from food than from a tin: hard cheese, yoghurt, calcium-rich mineral water, almonds, broccoli and fortified plant drinks.
Activates the proteins that build calcium into bone. Green leafy vegetables and fermented foods cover it — under coumarin blood thinning the amount stays steady rather than swinging.
Bone is a third protein scaffold, and the muscles that hold it need protein too. In older people too little protein is more common than too little calcium.
Needed for building calcium in and for vitamin D to work. A lack slows both — even when calcium and vitamin D are supplied in sufficient amounts.
About half of these lumps recede within a few years without any intervention. That is the most honest sentence about it — and the reason why waiting is a recognised treatment when it does not press and does not disturb.
The old household remedy — hence the English name “Bible cyst”. It sometimes works, because the cyst bursts. But it just as often cracks the bone underneath or injures tendons, and the cyst comes back in more than half of cases. The route via puncture does the same without the fracture.
Clearly worthwhile and well studied when deficient; fewer data for the wider uses. Fat-soluble — check blood levels at high doses.
Effective when deficient; effects on sleep and stress plausible but moderate. Too much causes loose stool.
Ganglions occur about three times more often in women, mostly between twenty and forty. Why is open — the difference is described, it is not explained.
About half disappear by themselves within a few years. That is why waiting here is a genuine option and not just being fobbed off — smashing it with a book is not.
A ganglion is a pouch of the joint capsule filled with joint fluid. It disappears by itself in about half of cases within years — no food influences that.
The old trick of smashing it with a book is dangerous and outdated. About half of ganglions disappear by themselves within years; until then it is about mobility and relief.
