A wrist ganglion cyst, also referred to as a synovial cyst, is a non-cancerous, fluid-filled lump that typically forms on the back or front of the wrist. Although generally harmless, it can sometimes lead to pain, discomfort, or restricted movement. By understanding the causes, recognizing the symptoms, and exploring effective treatments, individuals can better manage this condition.
What Causes a Wrist Ganglion Cyst?
A wrist ganglion cyst develops when synovial fluid, which normally lubricates joints and tendons, leaks and accumulates into a sac-like structure. While the exact cause is often unclear, several factors may contribute to its formation:
Repetitive Wrist Strain: Activities that involve frequent wrist movements, such as typing, writing, or playing sports, can increase the risk of cyst development.
Previous Injuries: A history of wrist sprains, fractures, or trauma may trigger the formation of a ganglion cyst.
Joint Inflammation: Conditions like osteoarthritis or other forms of joint inflammation can contribute to cyst development.
Genetic Factors: Some individuals may have a genetic predisposition to developing ganglion cysts.
