1. Case information: The patient was a 59-year-old male, a long-term office worker, who had low back pain with intermittent right lower extremity radiating pain for 2 years, aggravated for 2 weeks. At the time of consultation, the patient had numbness and severe pain in the right lower limb, and conservative treatment (dehydration and nerve nutrition) in the outpatient clinic was ineffective. The symptoms and signs on examination and imaging MR were consistent with an acute attack of lumbar disc herniation. 2. Treatment: After the outpatient treatment was not effective, it was difficult for him to be hospitalized for a long time for conservative treatment because of his work, so the study decided to routinely use radiofrequency ablation for lumbar disc herniation. The surgery was scheduled on the second day of admission (intraoperative pictures 1,2), and the symptoms disappeared completely after the surgery. Since there was no incision (only a needle eye), he was discharged on the second postoperative day. The hospital stay was 3 days. Intraoperative picture-1 Intraoperative picture-2 3. Treatment introduction Minimally invasive disc radiofrequency ablation simply means that under imaging surveillance, a radiofrequency needle is punctured to the local area of herniated disc compression, and through radiofrequency heating, protein coagulation of the herniated material occurs, and then the internal pressure of the herniated material decreases and retracts, relieving the nerve compression and irritation. Because the operation is simple and under the direction of imaging, for experienced spine surgeons, there is rarely injury to tissues organs and nerves, while the low radiofrequency temperature ensures safety before and after treatment without thermal injury. The puncture needle is only 0.7 mm (as thin as an infusion needle, see above), minimally invasive, painless, no incision, no bleeding, no postoperative effect on the stability of the spine, so there is little risk and quick recovery. It is especially suitable for lumbar disc bulge and inclusive disc herniation, and clinical observation also has good effect for some older and senior patients.
