To explore the treatment of multi-segmental lumbar disc herniation and spinal canal stenosis by laminectomy, removal of nucleus pulposus, fusion of intra-transverse process and general spine system(GSS) fixation. Methods From January 2004 to January 2006, 21 patients with multi-segmental lumbar disc herniation and spinal canal stenosis were treated by laminectomy, removal of nucleus pulposus and GSS pedicle screw spinal system. There were 14 males and 7 females with an average age of 53 years ranging from 46 to 61 years, and with an average disease course of 18 months ranging from 8 months to 15 years. All of the patients were examined by X-ray with AP position, lateral position and dynamic lateral position, CT and MRI, and all of them proved to be with multi-segmental lumbar disc herniation and different degrees of spinal canal stenosis. A total of 47 nucleuses were picked out, and 47 instable segments were filled in with granule selfbone. Results There were 21 patients who were followed up for 1 to 2 years with an average of 13 months. All patients achieved successful fusion and bony union postoperative from 8 to 12 months, and no artificial joint was formed. As to the cl inical results in 21 cases, according to the Macnab outcome criteria, 14 were excellent, 6 were good and 1 was poor, the excellent and good rate was 95.2%. Conclusion The methods of laminectomy, removal of nucleus pulposus, fusion of intra-transverse process and GSS system fixation are effective in treatment of multi-segmental lumbar disc herniation and spinal canal stenosis．
