A soft lump that comes and goes

One day, you notice a soft, springy lump on the back of your wrist that was not there before. You can move it gently with your finger; sometimes it only hurts when pressed, sometimes not at all.

Sometimes it disappears on its own after a while and then returns in the same place. This is not the result of a contusion or swelling. It is a wrist ganglion, also called a ganglion cyst.

What is actually happening?

The joint is surrounded by a joint capsule filled with fluid that lubricates it and protects it from friction. Sometimes a weak spot develops in this capsule or in a tendon sheath, through which the fluid starts to push outward, creating a bulge like an inner tube being squeezed through a tear in a tire—this is a joint hernia, or ganglion. The fluid that collects there thickens until it becomes gelatinous and forms an elastic lump under the skin.

The exact cause is not fully known, but it is most often associated with chronic overloading of the joint: repetitive hand work at a computer, playing an instrument, or frequently leaning on the wrist. It may also be a sign of greater or lesser wrist instability or damaged ligaments. It most often affects women between twenty and fifty years of age.

How can you recognize it?

  • a soft, elastic lump on the back or palm side of the wrist that can be moved slightly with a finger,
  • the lump sometimes disappears and then reappears in the same place after some time, often following overuse,
  • discomfort or pain when leaning on the hand, for example during push-ups or while typing,
  • tingling or reduced sensation in the fingers if the lump presses on a nearby nerve.

Why you should not wait

A ganglion itself is usually not dangerous, but as it grows it can eventually compress nearby structures, restricting movement and causing numbness in the hand.

A lump that appeared after an injury accompanied by swelling and restricted movement must be distinguished from other, more serious causes, such as damage to the wrist bones or ligaments. This cannot be determined by simply looking at it without an examination. A ganglion is often a symptom of various other wrist problems.

How we help

We begin with a consultation and an ultrasound examination, which confirms that it really is a ganglion rather than another lesion and shows which structure, such as a joint or tendon sheath, it is connected to.

If the lump does not hurt and does not restrict movement, observation is usually sufficient: some ganglia resolve spontaneously, especially when you limit overloading of the wrist.

If it is bothersome or grows quickly, it can be punctured and drained under ultrasound guidance, although the lump often grows back because the capsule itself and its stalk remain in place. In cases of recurrence, large size, or pressure on a nerve, we remove it surgically together with the stalk from which it arose, which greatly reduces the risk of recurrence compared with puncture alone.

There is one goal: a wrist without a recurring hernia.

Book a consultation

If you have noticed such a lump, especially with additional accompanying symptoms, do not wait. Make an appointment for a consultation. We will determine exactly what it is and tell you whether observation is enough or treatment is needed.
