Experimental: PTED group Percutaneous transforaminal endoscopic discectomy (PTED). Use German Joimax company production of intervertebral foramen mirror operation system, the prone position, by preoperative X-ray locating the skin into the needle point, intervertebral level away from the spine line 8 ~ 10 cm, 18 g needle insertion, the Kambin security triangle directly through the middle of pathological changes of intervertebral disc. After the success of the puncture, remove the needle core, injection of contrast agent, methylene blue (9:1) mixture disk imaging, replace the godet, slight rotation step by step to insert the expansion sleeve, X-ray perspective to determine work under the correct position. Radiofrequency ablation is used to form nucleus pulposus and fibrous ring and stop bleeding. | Procedure: PTED group The same as the descriptions in experimental group. |
Active Comparator: RA group Radiofrequency ablation (RA). Patients in prone position, local infiltration anesthesia, the puncture point for lesion clearance level, is apart from the spine line distance is 8 to 10 cm, in the perspective of the C-shaped arm X-ray machine; After the puncture needle was reached, the needle core was removed and the radiofrequency head was pierced through the puncture channel to the nucleus pulposus. In accordance with the method of melt into the shrinking exit, the intensity of the treatment by band 2, increased to 3 file again, according to the needle round mouth of 2, 4, 6, 8, 10, 12 o'clock to this process is repeated six times. |
