How long it takes for a compression fracture of the thoracic spine to become sedentary depends on the severity of the fracture and the type of treatment, etc. It usually takes about 3 months. If the condition is mild, the fracture compression is light, and there is no damage or compression of the nerves, this condition can be treated conservatively. Generally, it is necessary to stay in bed (hard board bed) for 40 to 60 days, and then you can sit up gradually. Generally, the fracture can be healed in about 3 months, and the sitting and standing time can be extended appropriately. If the compression of the thoracic spine is severe, accompanied by nerve and spinal cord damage, surgery can be performed as soon as possible. It takes about 3 months to fully recover after surgery. After recovery, if there is no abnormality after review, the sitting and standing time can be extended only under the doctor’s advice, but it is not recommended to sit and stand for too long, so as not to affect the postoperative recovery by sitting and standing too early or for too long. If thoracic compression fracture occurs, it is recommended to follow the doctor’s instructions for standardized treatment as early as possible, and regular review, under the guidance of the doctor to carry out activities and functional exercises, in order to reduce the adverse effects of the disease.
