Minimally invasive means to minimize trauma under the premise of ensuring the patient’s therapeutic outcome, and to promote the best possible recovery for the patient. Do not blindly pursue minimally invasive. Each minimally invasive treatment has its own indications and should not be used simply for the sake of minimally invasive. Take lumbar disc herniation as an example, for cases of simple herniation, not combined with bony spinal stenosis, segmental instability, etc., minimally invasive therapeutic measures such as discoscopy and intervertebral foraminoscopy are feasible. On the contrary, immobilization and fusion are required. The concept of minimally invasive treatment does not only refer to MED, PLED, etc., but also can be implemented in open surgery, such as MIS-TLIF, etc., limited decompression and immobilization, and reduction of muscle stripping. It is hoped that the majority of patients can treat minimally invasive rationally and not blindly reject open surgery.
