Microscopically assisted posterior lumbar interbody fusion was performed on 27 patients who had either spondylolisthesis or chronic lower back pain after previous lower back surgery. Overall improved satisfactory results occurred in 22 of 27 patients. Roentgenographic, stable, interbody fusion occurred in 22 of 27 patients. The poorest results and highest rate of pseudarthrosis occurred in patients with double-level fusions. Pseudarthrosis occurred in four of six patients with double-level fusions and unsatisfactory clinical results occurred in five of six patients with double-level fusions. Advantages of the microscopic technique are better examination of the surgical site, less blood loss, and less surgical dissection than other surgical salvage techniques. This procedure should be reserved for single-level pathology in the lumbosacral spine.
对27例患有腰椎滑脱或既往腰椎手术后慢性下腰痛的患者进行了显微镜辅助下腰椎后路椎间融合术。27例患者中有22例总体改善结果令人满意。27例患者中有22例出现了X线片显示的稳定椎间融合。双节段融合患者的结果最差，假关节发生率最高。6例双节段融合患者中有4例发生假关节，6例双节段融合患者中有5例临床结果不满意。与其他手术挽救技术相比，显微镜技术的优点是对手术部位的检查更好、失血更少、手术剥离更少。该手术应仅用于腰骶椎的单节段病变。
