1, the patient was supine, with a soft pillow under the shoulder so that the neck was slightly posterior, and the right side of the trachea at the above level was marked as the puncture point under X-ray surveillance to locate the intervertebral space level.
2, routine disinfection and towel laying, the left hand in the right tracheoesophageal sheath and vascular sheath between deep touch, touch the cervical vertebrae after the right hand to take a long needle No. 7 first from the puncture point vertical prick skin, inward posterior into the needle, local anesthesia after successful replacement of radiofrequency puncture needle, inward posterior into the needle.
3, under X-ray surveillance to adjust the needle position and direction, until the tip of the needle position is satisfactory, orthogonal to see the tip of the needle is located in the center of the intervertebral disc, lateral to see the tip of the needle is located in the intervertebral space at the level of the junction of the middle and posterior 1/3 of the disc.
4, measured impedance of 150-300 ohms, to 2HZ low frequency current test movement. 100HZ high frequency current replicates pain.
5.Radiofrequency destruction, adjust the temperature to 80-85°C, continuous action 60S, radiofrequency destruction 2-3 times.
6.After the end of RF, slowly inject 40ug/ml O3 (5-10) ML or so into the interdisk, out of the needle.
Aseptic dressing is applied to the puncture point. Observe for 20 minutes, the patient has no discomfort, and send back to the ward by flat car.
Postoperative routine dehydration and anti-infection treatment for 3 days.
Postoperative cervical brace is fixed for protection and rest is the mainstay for 3-6 months.
Indications.
1, there is prominence on the image and it is compatible with clinical symptoms and signs.
2.Nerve root symptoms are obvious and conservative treatment is ineffective.
3.Intervertebral discography can induce pain.
4.Anesthetic injection into the intervertebral disc has a more satisfactory analgesic effect.
5.Sympathetic cervical spondylosis.
Contraindications.
1, accompanied by a high degree of paralysis.
2.Significant intervertebral disc degeneration, the vertebral space is below 3MM.
3.Cervical instability.
4.Bone compression.
5.Bony spinal stenosis.
6, Rapid progression of symptoms.
7.Psychiatric disorders.
