    Abstract:
    A group of lumbar discherniation cases was treated with posterior discectomy and decompression with Spotlight working channel. We retrospectively studied these patients. To study and analyze the clinical efficacy and technical features of discectomy which is carried out with the Spotlight channel technology. The development of the minimally invasive spine surgery technology promotes new instruments and materials. For minimally invasive spine surgery in channel technology, the newly launched Depuy(Spine) working channel-Spotlight, which is a new generation of wide viewing angle, single-hole device for minimally invasive spine operations, has good prospects for clinical application. From March 2011 to March 2012, 21 patients who were diagnosed with lumbar disc herniation were treated with posterior discectomy and decompression with Spotlight working channel, then the lumbar and leg pain visual analogue scale (VAS) scores of before and after surgery and that of the follow-ups and the Oswestry Disability Index were analyzed. All patients were successfully operated, and also they received follow-ups for more than 1 year. The postoperative lumbar and leg pain VAS scores improved significantly compared with the preoperative ones (P < 0.05) and can effectively maintain (P > 0.05). The three time points of lumbar pain VAS were 7.80 ± 0.49, 1.51 ± 0.52 and 1.47 ± 0.59. The leg pain VAS were 7.53 ± 0.50, 1.58 ± 0.58 and 1.49 ± 0.67. During the follow-ups of the cases in this group, no case of disc herniation relapsed. Patients were satisfied with that. The Spotlight channel system is one of the surgical approaches to "minimally invasive spine technology with direct vision". It has a good range of surgical indications. It can be carried out flexibly and used widely, which means it will be easier for the surgeons to master.
