■本研究旨在比较2年随访期间退行性腰椎滑脱患者的斜斜(OLIF)和经椎间孔腰椎椎间融合术(TLIF)的临床结果。
■接受OLIF(OLIF组)或TLIF(TLIF组)的有症状的退行性腰椎滑脱患者在作者医院进行前瞻性登记并随访2年。主要结果是手术后2年的治疗效果[视觉模拟评分(VAS)和Oswestry残疾指数(ODI)相对于基线的变化];比较两组之间的差异。患者特征,射线照相参数,融合状态,并比较并发症发生率。
■总共,45名患者符合OLIF组的条件,47名患者符合TLIF组的条件。2年随访率分别为89%和87%,分别。主要结果的比较表明VAS-腿没有不同的变化(OLIF,3.4vs.TLIF,2.7),VAS-back(OLIF,2.5vs.TLIF,2.1),和ODI(OLIF,26.8vs.TLIF,30).TLIF组2年融合率为86.1%,OLIF组为92.5%(P=0.365)。OLIF组估计失血较少(中位数,200ml)比TLIF组(中位数,300ml)(P<0.001)。通过OLIF获得了更大的椎间盘高度恢复(平均值,4.6mm)比TLIF组(平均值,1.3mm)在术后早期(P<0.001)。OLIF组的沉降率低于TLIF组(17.5%vs.38.9%,P=0.037)。两组之间的总问题并发症发生率没有差异(OLIF,14.6%与TLIF,26.2%,P=0.192)。
■对于退行性腰椎滑脱,OLIF未显示出比TLIF更好的临床结果,除了失血少,较大的椎间盘高度恢复,和较低的沉降率。
UNASSIGNED: This
study aimed to compare the clinical outcomes between oblique (
OLIF) and transforaminal lumbar interbody fusion (TLIF) for patients with degenerative spondylolisthesis during a 2-year follow-up.
UNASSIGNED: Patients with symptomatic degenerative spondylolisthesis who underwent
OLIF (
OLIF group) or TLIF (TLIF group) were prospectively enrolled in the authors\' hospital and followed up for 2 years. The primary outcomes were treatment effects [changes in visual analog score (VAS) and Oswestry disability index (ODI) from baseline] at 2 years after surgery; these were compared between two groups. Patient characteristics, radiographic parameters, fusion status, and complication rates were also compared.
UNASSIGNED: In total, 45 patients were eligible for the OLIF group and 47 patients for the TLIF group. The rates of follow-up were 89% and 87% at 2 years, respectively. The comparisons of primary outcomes demonstrated no different changes in VAS-leg (
OLIF, 3.4 vs. TLIF, 2.7), VAS-back (
OLIF, 2.5 vs. TLIF, 2.1), and ODI (
OLIF, 26.8 vs. TLIF, 30). The fusion rates were 86.1% in the TLIF group and 92.5% in the
OLIF group at 2 years (P = 0.365). The OLIF group had less estimated blood loss (median, 200 ml) than the TLIF group (median, 300 ml) (P < 0.001). Greater restoration of disc height was obtained by OLIF (mean, 4.6 mm) than the TLIF group (mean, 1.3 mm) in the early postoperative period (P < 0.001). The subsidence rate was lower in the OLIF group than that in the TLIF group (17.5% vs. 38.9%, P = 0.037). The rates of total problematic complications were not different between the two groups (OLIF, 14.6% vs. TLIF, 26.2%, P = 0.192).
UNASSIGNED: OLIF did not show better clinical outcomes than TLIF for degenerative spondylolisthesis, except for lesser blood loss, greater disc height restoration, and lower subsidence rate.
