The main advantage of plasma myeloplasty (Necleoplasty) is the application of plasma ablation technology (Coblation), combining thermal coagulation and ablation to remove part of the nucleus pulposus, using low-temperature plasma ablation technology to vaporize part of the nucleus pulposus tissue of the disc in real time to achieve the purpose of reducing the volume of the nucleus pulposus; then use the precise thermal wrinkling technique to reduce the nucleus pulposus tissue contacted by the knife head Then, the nucleus pulposus is heated to approximately 70°C, which reduces the total volume of the nucleus pulposus and decreases the pressure in the disc to achieve decompression therapy. Compared with conventional microscopic nucleus pulposus removal, plasma minimally invasive nucleoplasty has the following advantages: 1. less trauma, maximum protection of the fibular wall; effective removal of tissue; 2. less postoperative degeneration of the disc; 3. less impact on the stability of the spine; low re-protrusion rate of the disc; less interference with the nerve roots; 4. plasma ablation only produces a temperature of 53°C, 1 mm beyond the surface of the blade The temperature is lower than 43°C, which will not produce thermal damage to other surrounding tissues under the correct operation; 5, with real-time ablation function, the decompression effect can be shown during the operation. 6.The head adopts bipolar structure, and the ablation head is only limited to the nucleus pulposus, so the electric field will not penetrate into the body, which is highly safe. Indications 1.Patients with pain and heaviness in shoulder and neck with obvious symptoms of radicular soreness, burning pain and numbness in upper limbs and MRI confirmed herniated disc in the corresponding interval; 2.Patients with pain in shoulder and neck with persistent headache, dizziness, tinnitus and vertigo and internal related diseases have been excluded. 3, discogenic lower back pain; positive discography, disc height ≥ 75% and central disc herniation; 4, for disc herniation: low back pain ≥ leg pain, MRI confirmed as inclusive disc herniation, positive discography. The application of myeloplasty for the treatment of patients with low back and leg pain should be based on a strict grasp of the above indications, combined with the following clinical features, which will improve its efficacy: patients with low back pain accompanied by radiating pain symptoms in the lower extremities, indicating that the lesion stimulates the nerve roots or nerve endings, and decompression can significantly reduce the stimulation of the nerve roots; imaging shows a small lateral disc herniation, the symptoms of such patients are based on nerve root irritation Once the pressure in the disc is reduced, the symptoms will be significantly improved. Conclusion: pulpal nucleoplasty is characterized by less injury, simple and safe operation, good results, no effect on the stability of the cervical spine, less operative time, and fast postoperative recovery, and has gradually become the ideal choice for patients between traditional surgery and conservative treatment.
