Hello, I often meet your situation. A patient like you has poor tolerance for surgery, so it is risky to change another one. But you should know that according to what you said, "the steel plate seems to be stainless steel, and the material of the steel plate used in surgery in 2007 seems to be 9000 pieces", then you only use ordinary steel plates, which can't be absorbed by your body, and it will cause harm to your body for a long time, such as steel plate fracture. Moreover, replacement can lead to osteoporosis. The other day, I had such an operation. The patient's lumbar plate was taken out last month in 2002, and it was very difficult to take it out. Several of them were dragged out of the pavilion! ! ! I suggest you take it out of the hospital, of course, provided that your doctor can stabilize your condition before operation, but you can tolerate the operation better! ! ! ! I wish you the best of health! !
