What is a Ganglion Cyst

Ganglion cysts are noncancerous lumps that most commonly develop along the tendons or joints of your wrists or hands. They also may occur in the ankles and feet. Ganglion cysts are typically round or oval and are filled with a jellylike fluid.

Dr. Bert Perey, MD, FRCPC, Orthopedic Surgeon, talks about what a ganglion cyst of the dorsal wrist is.

Ganglion Cyst of the Wrist

Ganglion cysts of the wrist. The ganglion cyst is one of the most common masses or bumps that appear at the wrist. The majority are on the dorsal, or also known as the back side of the wrist, and they’re usually visible when the wrist is bent. They can occur on the other side of the wrist as well. The cyst arises out of the joint, like a balloon on a stalk. And although these cysts can feel hard like bone, they actually contain a very thick, gelatinous, joint fluid, and it’s under pressure. They can appear quickly. They can fluctuate in size and they can disappear completely, but they may also recur. Most are not very symptomatic.

What’s the cause of a ganglion cyst? The exact cause remains unclear. Most of these occur in younger patients, especially women and especially with very mobile or flexible joints. They can, however, occur in both men and women and in all ages. Most ganglions are not caused by any specific trauma or injury, although a traumatic event to the wrist can lead to the appearance of the ganglion cyst. Local Physiotherapist.
