The time of functional exercise after lumbar spine fracture surgery needs to be determined comprehensively according to the specific injury, surgical method and the patient’s physical condition. After lumbar spine fracture surgery, you need to stay in bed for a period of time, and you can do bed exercises on the 2nd day after surgery, such as lumbar back muscle training during bed rest, such as tensing and lifting the leg, bending the knee and so on. If it is not serious lumbar spine fracture, after internal fixation surgery treatment for more than 3 weeks, you can consider wearing a brace to protect, get up and walk exercise, start to get up should not be too long. 2 months after the operation, you can gradually bend, rotate and other lumbar training, but the amplitude of the exercise should be avoided too large. If the fracture has healed completely after 3 months, normal lumbar activities can be carried out, such as bending to the pre-injury level, but avoid weight bearing for the time being.
