Subjects and ANt hods PTDPS were carried out on 306 patients withback or leg pain from Mar. 1993 to Dec. 1997. CT examination verified the intervertebral disc protrusion. WithCT-guidance a lumbar puncture needle of 20G was advanced to the site or sites around the affected nerve rootsand corticosteroid was injected into the subdural space. Results PTDPS were completed in all 306 patientssuccessfully. A 1-24 month follow -up was carried out on 186 cases. Of these 161 cases (86.5%) had good result, 16cases (8.6%) fair result and 9 cases (4.8%) without favorable result. Conclusion CT guided PTDPS is a safe,accurate, effective and minimally invasive method directing against the pathophysiolgy of sciatica caused byintervertebral disc protrusion. It is suitable for wider clinical application.展开更多
