Various surgical procedures have been recommended for the treatment of lumbar spondylolisthesis, but controversy still exists regarding the optimal surgical technique. In this study, we compared the clinical and radiologic outcomes of posterior lumbar interbody fusion (PLIF) and transforaminal lumbar interbody fusion (TLIF) with pedicle screw fixation in the treatment of single-level lumbar spondylolisthesis. Ninety-four patients underwent lumbar interbody fusion with pedicle screw fixation for the treatment of adult lumbar spondylolisthesis. Forty-six had PLIF with two cages and pedicle fixation (group 1), and 48 had TLIF with one cage and pedicle fixation (group 2). The follow-up was performed clinically using the visual analog scale (VAS) and Oswestry Disability Index (ODI) Questionnaires. Outcome scores were assessed 3, 6, and 12 months after surgery. Radiographs were obtained postoperatively and at regular intervals for 6 months. Perioperative outcomes such as surgery time, blood loss, length of hospital stay, and incidence of surgical complications were also recorded. Estimated blood loss and operative time in the TLIF group were significantly lower than those in the PLIF group. VAS for back pain and ODI were significantly better in the TLIF group than the PLIF group. However, at the time of the last follow-up, both groups had similar slip reduction and spinal fusion rates. More complication rate was encountered in the PLIF group compared to the TLIF group. Our study showed that TLIF is superior to PLIF with respect to functional outcome and complication rate in grade I/II single-level lumbar spondylolisthesis.

经椎间孔腰椎椎间融合术（TLIF）与后路腰椎椎间融合术（PLIF）在单级腰椎滑脱症的治疗中

已经推荐了各种手术方法来治疗腰椎滑脱，但是关于最佳手术技术仍存在争议。在这项研究中，我们比较了后路腰椎椎间融合术（PLIF）和经椎间孔腰椎椎间融合术（TLIF）与椎弓根螺钉固定术治疗单级腰椎滑脱的临床和影像学结果。94例患者接受腰椎椎体间椎弓根螺钉融合术治疗成人腰椎滑脱。46例有两个笼和椎弓根固定的PLIF（第1组），有48个有1个笼和椎弓根固定的TLIF（第2组）。使用视觉模拟量表（VAS）和Oswestry残疾指数（ODI）问卷在临床上进行随访。评估结果得分为3、6，术后十二个月。术后并定期间隔6个月获得射线照相。还记录了围手术期结果，例如手术时间，失血量，住院时间和手术并发症的发生率。TLIF组的估计失血量和手术时间显着低于PLIF组。TLIF组的背痛和ODI的VAS显着优于PLIF组。然而，在最后一次随访时，两组滑石减少率和脊柱融合率相似。与TLIF组相比，PLIF组的并发症发生率更高。我们的研究表明，在I / II级单级腰椎滑脱症的功能结局和并发症发生率方面，TLIF优于PLIF。术后并定期间隔6个月获得射线照相。还记录了围手术期结果，例如手术时间，失血量，住院时间和手术并发症的发生率。TLIF组的估计失血量和手术时间显着低于PLIF组。TLIF组的背痛和ODI的VAS显着优于PLIF组。然而，在最后一次随访时，两组滑石减少率和脊柱融合率相似。与TLIF组相比，PLIF组的并发症发生率更高。我们的研究表明，在I / II级单级腰椎滑脱症的功能结局和并发症发生率方面，TLIF优于PLIF。术后并定期间隔6个月获得射线照相。还记录了围手术期结果，例如手术时间，失血量，住院时间和手术并发症的发生率。TLIF组的估计失血量和手术时间显着低于PLIF组。TLIF组的背痛和ODI的VAS显着优于PLIF组。然而，在最后一次随访时，两组滑石减少率和脊柱融合率相似。与TLIF组相比，PLIF组的并发症发生率更高。我们的研究表明，在I / II级单级腰椎滑脱症的功能结局和并发症发生率方面，TLIF优于PLIF。还记录了失血量，住院时间和手术并发症的发生率。TLIF组的估计失血量和手术时间显着低于PLIF组。TLIF组的背痛和ODI的VAS显着优于PLIF组。然而，在最后一次随访时，两组滑石减少率和脊柱融合率相似。与TLIF组相比，PLIF组的并发症发生率更高。我们的研究表明，在I / II级单级腰椎滑脱症的功能结局和并发症发生率方面，TLIF优于PLIF。还记录了失血量，住院时间和手术并发症的发生率。TLIF组的估计失血量和手术时间显着低于PLIF组。TLIF组的背痛和ODI的VAS显着优于PLIF组。然而，在最后一次随访时，两组滑石减少率和脊柱融合率相似。与TLIF组相比，PLIF组的并发症发生率更高。我们的研究表明，在I / II级单级腰椎滑脱症的功能结局和并发症发生率方面，TLIF优于PLIF。TLIF组的背痛和ODI的VAS显着优于PLIF组。然而，在最后一次随访时，两组滑石减少率和脊柱融合率相似。与TLIF组相比，PLIF组的并发症发生率更高。我们的研究表明，在I / II级单级腰椎滑脱症的功能结局和并发症发生率方面，TLIF优于PLIF。TLIF组的背痛和ODI的VAS显着优于PLIF组。然而，在最后一次随访时，两组滑石减少率和脊柱融合率相似。与TLIF组相比，PLIF组的并发症发生率更高。我们的研究表明，在I / II级单级腰椎滑脱症的功能结局和并发症发生率方面，TLIF优于PLIF。
