Enlargement of the big toe joint may be due to bunion, bunion degeneration, gout, rheumatoid arthritis, old trauma and other factors, and need to consult a doctor in time to find out the cause.
1. Bunion: Due to congenital development or wearing tight shoes for a long period of time, the bunion is compressed, resulting in localized bunion deformity, thus causing bunion, which is easily accompanied by bunionitis, leading to pain.
2. Degeneration of the bunion joint: Most common in the elderly, due to chronic strain, resulting in wear and tear of the articular cartilage, secondary osteophytes, resulting in the bunion joint becoming larger.
3. Gout: When the purine metabolism in the body is disturbed, too much uric acid is produced, which may be deposited in the articular surface of the bunion, and some of them may form gout stones, thus causing the joints to become bigger, accompanied by obvious redness, swelling and pain, and the skin temperature is elevated.
4. Rheumatoid arthritis: It may cause lesions of the synovial membrane of the joints, leading to destruction of the cartilage, which may cause swelling, deformity, and limitation of movement of the joints.
5. Old trauma: When the bunion suffers from trauma resulting in joint injury or fracture, if it is not treated in time, local deformity or joint enlargement may occur.
In short, after the big toe joint becomes enlarged, it is necessary to consult a professional doctor to find out the cause of the disease in time to avoid delaying the condition.
