The hazards of spinal surgery can be divided into two main categories: the first category, refers to the spinal surgery, easy to accelerate the degenerative changes of neighboring spinal segments, such as easy to appear in the neighboring segments of the spinal vertebral instability, vertebral body slippage, as well as secondary spinal stenosis, such as the cause of neighboring segments of the intervertebral disc degenerative changes accelerated, resulting in the neighboring segments of the intervertebral disc bulging, protruding, and even prolapse, and so on. The second major category, the hazards of spinal surgery, is the possibility of intraoperative damage to important neural tissues, such as damage to the dural sac, which can cause persistent cerebrospinal fluid leakage. If the nerve root is damaged, it can cause paralysis of the upper limbs or lower limbs, etc., and recovery is very difficult.
