Symptoms of thoracic spondylolisthesis may be caused by age factor, overweight, chronic strain, autoimmune diseases, etc. 1. Age factor: with the gradual aging of the age, the joints will be aging, the mechanics of the joints will also change, the local will be abnormal force, over time, will form osteophytes. 2. Overweight: If you are too obese and overweight, the force on the thoracic vertebrae will be relatively large, and it is easy to stimulate repeatedly, contributing to the formation of bone spurs, which will eventually lead to osteophytes. 3. Chronic strain injury: it may be caused by overstrain of joints, which will lead to the loss of joint ligaments for local protection, thus triggering local osteophytes. 4. Autoimmune diseases: for example, systemic lupus erythematosus, rheumatoid arthritis, etc., are prone to promote the formation of bone spurs in the thoracic spine, thus leading to osteophytes. The symptoms of thoracic vertebral osteophytes may also be caused by genetic factors such as congenital deformities, etc. It is recommended to go to the hospital in a timely manner, to clarify the cause of targeted treatment.
