The main causes of dorsal foot ganglion cysts are as follows: 1. Chronic strain: Prolonged standing or walking can lead to repeated friction between tendons and tendon sheaths on the dorsum of the foot, triggering an aseptic inflammatory response. Gradual accumulation of exudate may eventually form a cyst. 2. Trauma: External impact or compression to the dorsum of the foot damages local soft tissues, causing inflammatory exudation. Accumulated exudate may then form a cyst. 3. Bacterial infection: Local bacterial infection around the tendon sheath may result in persistent inflammatory substances that fail to be completely cleared. These substances can irritate the tendon sheath and become encapsulated, leading to the formation of a ganglion cyst. 4. Mucoid degeneration of connective tissue: This is a benign condition caused by injury, inflammation, or other factors, resulting in mucoid degeneration of connective tissue on the dorsum of the foot, which subsequently forms a cyst. 5. Tissue malnutrition: Deficiency of essential nutrients in the patient may lead to poor tissue nutrition in the dorsum of the foot, contributing to the development of a ganglion cyst. The specific cause should be determined based on individual circumstances.
