Minimally invasive surgery of the lumbar spine is not very risky for the following reasons: 1. Because this technology is already very mature. The minimally invasive surgery for the lumbar spine has been carried out for many years, and the technical difficulty of such operations is not too great in clinical practice, and many doctors are able to master this technology. 2. The imaging equipment for the lumbar spine is very advanced. The lumbar spine has a series of minimally invasive surgeries that are assisted by very advanced imaging equipment, for example, in some hospitals there are very formal DSA operating rooms, so you can see the lesion very clearly and guide the relevant surgical operations. 3, the anesthesia for this type of surgery is relatively small anesthesia. For example, when doing local painful point closure or ozone injection, even local infiltration anesthesia can be chosen, so the risk of anesthesia is relatively small.4. Less invasive. When performing some minimally invasive operations on the lumbar spine, it is possible that the skin incision is only 1-2 cm, and the local and internal trauma is also very small. Therefore, in summary, for the treatment of such diseases, the risks associated with minimally invasive surgery are not large.
