There are various minimally invasive procedures for lumbar disc herniation, and the specific operation process is roughly as follows: 1. Ozone therapy: guided by CT or X-ray machine, puncture to the corresponding diseased disc, inject ozone through a syringe needle to atrophy the herniated disc and achieve decompression; 2. Radiofrequency therapy: guided by CT or X-ray machine, puncture to the corresponding diseased segment, ablate through radiofrequency to achieve decompression; 3, Intervertebral foraminoscopy: under the guidance of X-ray machine, puncture to the corresponding diseased segment and remove the herniated disc to achieve the purpose of decompression. This procedure is a more popular minimally invasive decompression modality; 4. Other modalities: decompression is performed through open surgical instruments under minimally invasive access.
