Introduction of plasma ablation myeloplasty Recently, the orthopedic department of our hospital has introduced the world’s latest minimally invasive treatment technology equipment for lumbar disc herniation, namely plasma ablation myeloplasty, which uses the low-temperature ablation function of plasma and adopts the percutaneous puncture method to ablate and reduce the volume of the nucleus pulposus, immediately relieving the increased pressure in the disc and relieving the patient’s compression symptoms, and the low-temperature effect of plasma obviously improves the internal chemical environment caused by disc degeneration and induces the synthesis of repair factors. The plasma cryogenic effect significantly improves the internal chemical environment caused by disc degeneration, induces the synthesis of repair factors, and facilitates local repair. This technique can effectively achieve safe reduction of the nucleus pulposus with no damage to the surrounding important spinal structures, nucleus pulposus, annulus fibrosus, end plate, spinal cord and nerve roots, and no necrosis, etc. Indications for this technique (patient selection) 1. age < 50 years, duration of disease < 5 years 2. conservative treatment is ineffective or less effective, and the effect of open surgery cannot be guaranteed 3. sedentary or standing low back pain accompanied by hip or lower extremity release/shooting pain. (Nerve root irritation related to disc pressure is the main symptom) 4, disc height > 75% 5, MRI: diagnosis of inclusive disc expansion/protrusion 6, positive discography Post-operative recovery process (efficacy) u Discharge/shooting pain in the hip and lower extremity can disappear within a short period of time. The soreness/pain in the lumbar area is not obvious or worsens. uSignificant reduction of symptoms after 3-5 days. uRecovery to the best condition 4-6 weeks after surgery.
