A wrist ganglion is fluid filled. It may arise from your tendons or your wrist joint.
The exact cause of ganglion cysts is unknown, but they are believed to develop as a result of repetitive stress or irritation to the joint or tendon. The cyst itself is filled with a thick, jelly-like fluid called synovial fluid, which is normally found in joints.
Ganglion cysts are usually round or oval-shaped, and they may vary in size from a few millimeters to several centimeters in diameter. In some cases, the cyst may be visible and easily felt, while in others, it may be smaller and less noticeable. Ganglion cysts are typically painless, but they can cause discomfort or mild pain if they press on a nearby nerve or interfere with joint movement.
The diagnosis of a ganglion cyst is usually made based on a physical examination and dedicated imaging tests such as X-rays, ultrasound and MRI.
Wrist Ganglion Treatment
A ganglion may be investigated with an MRI of your wrist. It is seen here as a white structure.
Treatment options for a wrist ganglion may include:
Observation:
If the cyst is small, painless, and not causing any functional impairment, a “wait-and-see” approach may be recommended, as some cysts may resolve on their own over time.
Splinting or bracing:
Wearing a wrist splint or brace can help immobilise the joint, alleviate symptoms, and promote cyst regression.
Aspiration/ Steroid Injection:
Drainage or injection with steroids of a ganglion can be attempted. A ganglion frequently recurs after this.
Surgery:
The most definitive treatment for a wrist ganglion is surgical removal, especially if other treatments have failed or if it is causing you discomfort.
