Objective To investigate the clinical effect of guide-rod visualized foraminoplasty in the treatment of lum-bar disc herniation.Methods The 76 patients with lumbar disc herniation treated by percutaneous foraminoplasty nu-cleus pulposus discetomy were divided into guide-rod visualization group(39 cases treated with visualized foramin-oplasty)and TESSYS group(37 cases treated with transforaminal endoscopic spine system),according to different surgical methods.Surgical indexes,pain VAS and ODI were compared between the two groups.Results All patients were followed up for 6～13 months.There was no statistical difference in hospital stay between the two groups(P>0.05).The frequency of intraoperative fluoroscopy and operation time were less(shorter)in the guide-rod visualiza-tion group than those in the TESSYS group(P<0.05).Pain VAS and ODI:at 3 d postoperation and the last follow-up,both groups were decreased than those before surgery(P<0.05);there were no statistical differences in postoper-ative various time-point between the two groups(P>0.05).Conclusions It is a safe and effective foraminoplasty technique for the treatment of lumbar disc herniation,guide-rod visualized foraminoplasty can reduce the frequency of intraoperative fluoroscopy,shorten the operation time,and improve the efficiency and accuracy of foraminoplasty.
