1, surgical trauma is small: compared with conventional open surgery, minimally invasive spine surgery incision is smaller, and the damage to the paravertebral muscles is significantly reduced. Conventional open surgery requires extensive stripping and retraction of the muscles of the low back, and sometimes the thoracic and abdominal cavities need to be opened, which is very traumatic for the patient, while minimally invasive spine surgery is significantly less traumatic than conventional open surgery. 2, satisfactory results: research shows that many patients with conventional open surgery do not have significant postoperative back pain relief, and the postoperative magnetic resonance examination found that the muscles of the low back in the longer postoperative period have obvious edema and scarring, which is mainly due to open surgery on the paravertebral muscle soft tissue damage caused by too much. Minimally invasive spine surgery, on the other hand, has little damage to the paravertebral muscles and other soft tissues, so patients rarely experience low back pain after surgery, and the results are satisfactory. 3, fast recovery: Conventional open surgery is more destructive to the structure of the spine and to the paravertebral muscles, so it is easy to cause postoperative instability of the spine, and the local pain of the incision lasts longer, often requiring a recovery period of 1-3 months after surgery. Minimally invasive spine surgery, on the other hand, has a faster recovery because it causes less damage to the spinal structure and soft tissue of the paravertebral muscles. 4. Less surgical bleeding: Minimally invasive surgery has small exposure and small incisions, so there is little bleeding, and often no blood transfusion is needed, which is beneficial to the patient’s recovery. 5.Small skin incision, small scar, more beautiful appearance: The incision of conventional open surgery of lumbar spine is generally 10-15cm, sometimes even longer, and with the reaction of sutures, the scar is often very large, and after healing, it looks like a big centipede, which seriously affects the beauty, especially for women who love beauty, it is often difficult to accept. Minimally invasive surgery is generally 2-5cm incision, but also the use of plastic surgery suture method, postoperative scar is small, very conducive to aesthetics. 6, short hospital stay, can reduce medical costs: minimally invasive spine surgery patients in the hospital after a short hospital stay, and can return to work earlier, so that the limited medical resources are saved. 7. Easier remedy in case of disease recurrence and relapse: Whether minimally invasive surgery or open surgery, recurrence and relapse may occur after surgery, while minimally invasive surgery is simple and effective when operated again because of less damage to the spine and tissues. In contrast, if extensive exposure, laminectomy, or spinal fusion is done, reoperation is very difficult and less effective.
