Degenerative changes of the thoracic spine are usually caused by trauma, strain and age factors. The main reasons for degenerative changes of the thoracic spine are the above three. The specific analysis is as follows: 1. Strain: patients will have degenerative changes of the thoracic spine after strain, such as spur growth. 2. Age: As the elderly patients grow older, bone metabolism will also appear obstacles, and patients will also have degenerative changes in the thoracic spine, manifested as local bone hyperplasia. 3. Trauma: it can cause fracture or dislocation of the thoracic spine, stimulate local hyperplasia, and lead to degenerative changes of the thoracic spine. Therefore, the reasons for degenerative changes of the thoracic spine are as follows. Early manual intervention can reduce the degenerative changes of the thoracic spine by avoiding the above problems. The clinical symptoms caused by thoracic vertebra degeneration can be alleviated by strengthening chest and back muscle exercise at ordinary times and enhancing the stability of thoracic vertebra.
