Radiofrequency ablation I. Indications It is applicable to the treatment of discogenic cervical spondylosis, lumbar disc herniation and spinal stenosis. Second, surgical instruments and equipment CT or C-arm X-ray fluoroscopy machine, plasma surgery system, disposable scalpel tip, disposable puncture needle. Treatment 1. Preoperative medication: Dexamethasone 10mg dissolved in saline 250ml intravenously to prevent allergic reaction. 2. Positioning: Position the lesion at the CT site before treatment to determine the puncture site and angle. 3, operation: (1) cervical spine: take supine position, shoulder and back padding to make the neck hyperextended, so that the cervical spine is in a natural supine position, expose the neck, C-arm X-ray machine surveillance to locate the lesion vertebral space, routine sterilization spread sterile towel, with 1% lidocaine line puncture point skin through the trachea, esophagus and the gap between the common carotid artery to deep fascia layer by layer infiltration anesthesia, with the thumb to separate the sternocleidomastoid muscle and cervical artery and vein, with The C-arm X-ray machine monitors the accurate position of the needle tip in the positive and lateral positions, injects 0.5 ml of Onepac into the intervertebral disc to perform discography, confirms that the intervertebral disc fibrous ring is not ruptured, installs the radiofrequency cutter head and performs radiofrequency ablation, withdraws the radiofrequency cutter head and the puncture needle after the operation, covers the puncture point with a dressing, and applies a pressure dressing. (2) Lumbar spine: ①Lumbar paravertebral method: prone position, lumbar padding to make the lumbar area bend naturally, expose the skin of the lumbar area, locate the lesion intervertebral space under the surveillance of C-arm X-ray machine, routinely sterilize and lay sterile towel, then infiltrate the skin of the puncture site layer by layer with 1% lidocaine 8ml, and enter the needle at an angle of 45 degrees with the sagittal plane through the skin, subcutaneous, deep fascia, sacrospinous muscle, lumbar square muscle, lumbaris major muscle through the safety triangle to reach the intervertebral disc. The C-arm X-ray machine monitors the accurate position of the tip of the needle in the positive and lateral position, injects 0.5 ml of Onepac to perform discography, and the C-arm X-ray machine monitors to confirm whether the intervertebral disc fibrous ring is ruptured, installs the radiofrequency cutter head and performs radiofrequency ablation, withdraws the radiofrequency cutter head after the operation, withdraws the puncture needle, covers the puncture point with a dressing, and applies a pressure dressing. (2) supra-articular eminence method: prone position, lumbar padding to make the lumbar region bend naturally, expose the skin of the lumbar region, locate the lesioned intervertebral space under the surveillance of C-arm X-ray machine, routinely sterilize and spread sterile towel, then infiltrate the skin of the puncture site layer by layer with 1% lidocaine 8ml, enter the intervertebral disc through the skin, subcutaneous tissue, deep lumbar fascia, sacrospinous muscle, lumbaris major muscle and nerve roots with the needle at an angle of 45 degrees to the sagittal plane, and enter the intervertebral disc under the C-arm X-ray machine. The C-arm X-ray machine monitors the accurate position of the tip of the needle in the positive and lateral position, injects 0.5 ml of Onepac to perform discography, and the C-arm X-ray machine monitors to confirm whether the intervertebral disc fibrous ring is ruptured, installs the radiofrequency cutter head and performs radiofrequency ablation, withdraws the radiofrequency cutter head after the operation, withdraws the puncture needle, covers the puncture point with dressing, and wraps with pressure.
