Whether the lumbar compression fracture with internal fixation can exercise or not depends on the postoperative time and fracture healing. 1. Early postoperative period of lumbar compression fracture: Generally speaking, it is not recommended to get out of bed within 3 days; after 2 weeks, you can wear a waist cuff to get out of bed to increase the strength of lumbar muscles and enhance the stability of lumbar vertebrae, but it is not recommended to exercise strenuously. 2. Late postoperative lumbar compression fracture: after 3 months, according to the patient’s fracture healing condition, the amount of exercise can be appropriately strengthened to enhance the lumbar back muscle exercise, the exercise should be from light to heavy, but if you want to fully return to daily life exercise, it may take 1~2 years or even longer. Patients with lumbar compression fracture who have undergone internal fixation are recommended to undergo regular review in the hospital and gradually increase the amount of exercise according to the healing of the fracture to avoid the adverse consequences of excessive exercise.
