The causes of bunions can be categorized into congenital and acquired factors. Congenital factors are mainly due to underdevelopment of thumb-related structures, while acquired factors include life habits, inflammation, trauma, etc.
1. Congenital factors: related to heredity, most of the patients have related family history, such as underdevelopment of local joints, muscles or nerves of the thumb, resulting in bunions.
2. Lifestyle habits: If you wear shoes with pointed and narrow toes for a long time, such as high-heeled shoes, the toes may be deformed by long-term extrusion, which may show symptoms of bunion, and standing or walking for a long time may also cause extrusion of the thumb, resulting in bunion.
3. Inflammation: In rheumatoid arthritis, the bunion is localized and dislocated outward, which may lead to joint deformity and bunion.
4. Trauma: If the thumb joint has a fracture, muscle injury, etc., coupled with the patient’s inappropriate activities, local deformity may occur, and the patient may show symptoms of bunion.
If bunion occurs, it is recommended that the patient consult a doctor in a timely manner to clarify the cause of the disease and then under the guidance of the doctor for treatment.
