1, less traumatic surgery: compared with conventional open surgery, minimally invasive spine surgery has smaller incisions and significantly less damage to the paraspinal muscles. Conventional open surgery requires extensive stripping and retraction of the muscles of the lower back, and sometimes it is necessary to open the thoracic and abdominal cavities, which is very traumatizing to the patients, while minimally invasive spine surgery is significantly less traumatic than conventional open surgery. 2. Satisfactory results: Studies have shown that many conventional open surgery patients do not have significant pain relief in the low back after surgery, and postoperative magnetic resonance examinations have found that the muscles of the low back have obvious edema and scarring for a long period of time after surgery, which is mainly due to the excessive damage of open surgery to the soft tissues of paravertebral muscles. Minimally invasive spine surgery, on the other hand, has little damage to the soft tissues such as paraspinal muscles, and patients rarely experience postoperative low back pain, resulting in a satisfactory outcome. 3, fast recovery: conventional open surgery due to the structure of the spine and more damage to the paraspinal muscles, so easy to cause postoperative spinal instability, and the incision of local pain lasts for a long time, and often need 1-3 months of postoperative recovery period. Minimally invasive spine surgery, on the other hand, has less damage to the spinal structure and soft tissues of the paraspinal muscles, resulting in faster recovery after surgery. 4, less surgical bleeding: minimally invasive surgery small exposure, small incision, so bleeding is also very small, often do not need blood transfusion, conducive to the patient’s recovery. 5.Small skin incision, small scar, more beautiful appearance: lumbar conventional open surgery incision is generally 10-15cm, sometimes even longer, and coupled with the suture reaction, often the scar is very large, after healing, it is like a big centipede, seriously affecting the aesthetic appearance, especially for women who love beauty, it is often difficult to accept. Minimally invasive surgery, on the other hand, the incision is generally 2-5cm, but also plastic surgery suture method, postoperative scar is small, very conducive to aesthetics. 6, short hospitalization time, can reduce medical costs: minimally invasive spine surgery patients in the hospital after a short hospital stay, and can return to work earlier, which saves the limited medical resources. 7. Easier remedy for disease recurrence and reoccurrence: no matter minimally invasive surgery or open surgery, there may be recurrence and reoccurrence after surgery, while minimally invasive surgery is simple to operate again due to less damage to the spine and tissues, and the efficacy is also good. In contrast, if extensive exposure, laminectomy, or spinal fusion is performed, reoperation is difficult and less effective.
