Minimally invasive lumbar discectomy and internal fixation fusion brings the patient not only aesthetic appearance (4 cm incision with only three stitches), but more importantly, the patient can really benefit from the minimally invasive approach: the minimally invasive incision is small and enters through the muscular space, reducing the damage to the posterior stable structures of the spine such as ligaments and spinous processes, maintaining the stability of the operated segment, and the patient can be on the floor the day after surgery without the need for brace protection. It reduces the disturbance to the dura and other structures and avoids postoperative adhesions. The surgical approach is lateral to the nerve root, reducing the chance of intraoperative pulling of the nerve root and reducing the chance of nerve injury. The surgical bleeding is low, with 10-20 ml less than the 100-300 ml of traditional surgery. If the indications are chosen properly, it will lead to good treatment results for the patient.
