Ganglion cyst of the wrist

Causes

Ganglion cysts are frequently observed in younger individuals between 15 and 40 years of age and more often in elderly women. The cause of ganglion cyst formation is unknown. Hypotheses suggest that it can develop:

Following minor, repetitive injuries particularly during prolonged sport activities

Consequence of damage to the joint capsule causing the synovial fluid to leak outside the capsule and become enclosed in a cyst

Due to phalangeal joint arthritis at the finger extremities in older adults
