1 Minimal surgical trauma: Compared with conventional open surgery, minimally invasive spine surgery has smaller incision and less damage to paravertebral muscles. Satisfactory curative effect: Studies show that many patients with low back pain after routine open surgery are caused by excessive injuries to paraspinal muscles and soft tissues caused by open surgery. However, minimally invasive spinal surgery has little damage to paraspinal muscles and other soft tissues, and rarely causes low back pain after operation, with satisfactory results. 3. Fast recovery: Conventional open surgery usually needs a recovery period of 1~3 months due to the great damage to the spinal structure and paraspinal muscles, while minimally invasive surgery for the spinal column has a quick recovery due to the small damage to the spinal structure and paraspinal muscles and soft tissues. 4 Less bleeding during operation: Minimally invasive surgery has small exposure, small incision and less bleeding, and often does not require blood transfusion, which is beneficial to patients' recovery. 5 The skin incision is small, the scar is small, and the appearance is more beautiful: the incision of conventional open lumbar surgery is generally 10~ 15cm, while the incision of minimally invasive spinal surgery is generally 0.7~5cm, so plastic and cosmetic suture can be used, which is very beneficial to aesthetics. 6 short hospitalization time can reduce medical expenses and be easily accepted by patients.
