A prospective study was carried out to estimate the percentage of disc removal at the time of lumbar laminectomy and discectomy. Intraoperative discograms were obtained which afforded a method of calculating the percentage of disc removal. The technique permits localization of the level of discectomy and provides a means of detecting anterior annulus perforation intraoperatively, which we hope will reduce the morbidity of anterior annulus perforation. A comparison between the efficacy of disc removal (microdiscectomy vs. laminectomy) is also presented.
进行了一项前瞻性研究，以估计腰椎椎板切除术和椎间盘切除术时椎间盘切除的百分比。术中获取了椎间盘造影，这提供了一种计算椎间盘切除百分比的方法。该技术可定位椎间盘切除的水平，并提供术中检测前环穿孔的方法，我们希望这将降低前环穿孔的发病率。还比较了椎间盘切除（显微椎间盘切除术与椎板切除术）的疗效。
