Thoracic spine fracture can be immobilized by external fixation with cast or fixator outside the body and internal fixation with fixation device inside the body after surgery, and the mode of immobilization is determined by the type of fracture as well as the severity of the fracture. 1. External fixation: External fixation is commonly used to fix thoracic vertebral fracture of lesser degree. The plaster bandage fixation and brace fixation are commonly used in thoracic vertebral fracture to avoid displacement of the fracture and to promote the healing of the fracture. 2. Internal fixation: It is commonly used for the fractures with more serious degree of injury, which need surgical internal fixation in order to complete the restoration of the fracture, and the specific operation should be decided according to the specific conditions of the fracture. If thoracic spine fracture occurs, it is recommended to actively cooperate with doctors to carry out standardized treatment to promote the healing of the fracture as soon as possible.
