Abstract
Purpose: To evaluate the outcomes of Oblique lumbar interbody fusion (OLIF)combined with anterolateral screw fixation (AF) and Stress Endplate Augmentation(SEA) versus OLIF-AF in the treatment of degenerative lumbar spondylolisthesis (DLS)with osteoporosis (OP).
Methods: 30 patients underwent OLIF-AF-SEA (SEA group) were matched with 30 patients received OLIF-AF (control group), in terms of sex, age, body mass index (BMI) and bone mineral density (BMD). Clinical outcomes including visual analog scale (VAS) score of the lower back pain (VAS-LBP), leg pain (VAS-LP), and Oswestry Disability Index (ODI) were evaluated at different postoperative intervals and comparedwith their preoperative counterparts. Radiographic outcomes such as disk height (DH), slip distance (SD), lumbar lordosis (LL), segmental lordosis (SL), cage subsidence (CS) rate and fusion rate were evaluated at different postoperative intervals and compared with their preoperative counterparts.
Results: SEA group presented to be better at 3-month and 12-month follow-up, the VAS-LBP, VAS-LP and ODI scores of the SEA group were significantly lower than the control group (3-month SEA vs control: 2.30±0.70 vs 3.30±0.75, 2.03±0.72 vs 2.90±0.76,15.60±2.36 vs 23.23±3.07, respectively, all p<0.05. VAS-LBP and ODI 12-month SEA vs control: 1.27±0.74 vs 1.93±0.58, 12.20±1.88 vs 14.43±1.89,respectively, all p<0.05). At 24-month follow-up, both groups showed no difference in fusion rate (83.33% vs 90.00%, p=0.45), while SEA group showed a lower CS rate (13.33% vs 53.33%, p<0.05).
Conclusion: OLIF-AF-SEA was safe with no adverse effects and resulted in lower CS rate and better sagittal balance. OLIF-AF-SEA is a promising surgical method for treating patients with DLS-OP.
目的:评估斜行腰椎椎体间融合术(OLIF)联合前外侧螺钉固定术(AF)和应力终板增强术(SEA)与OLIF-AF治疗骨质疏松症(OP)退行性腰椎滑脱症(DLS)的疗效。方法:30 名接受 OLIF-AF-SEA 治疗的患者(SEA 组)与 30 名接受 OLIF-AF 治疗的患者(对照组)在性别、年龄、体重指数(BMI)和骨质密度(BMD)方面进行对比。在不同的术后时间间隔评估临床结果,包括下背痛(VAS-LBP)、腿痛(VAS-LP)的视觉模拟量表(VAS)评分和奥斯韦特里残疾指数(ODI),并与术前进行比较。在不同的术后时间间隔评估椎间盘高度(DH)、滑移距离(SD)、腰椎前凸(LL)、节段前凸(SL)、椎笼下沉率(CS)和融合率等影像学结果,并与术前进行比较:结果:SEA组在3个月和12个月的随访中表现更好,SEA组的VAS-LBP、VAS-LP和ODI评分明显低于对照组(3个月SEA vs 对照组:分别为2.30±0.70 vs 3.30±0.75、2.03±0.72 vs 2.90±0.76、15.60±2.36 vs 23.23±3.07,均为P):OLIF-AF-SEA安全无不良反应,CS率较低,矢状面平衡较好。OLIF-AF-SEA是治疗DLS-OP患者的一种很有前景的手术方法。
期刊介绍:
"European Spine Journal" is a publication founded in response to the increasing trend toward specialization in spinal surgery and spinal pathology in general. The Journal is devoted to all spine related disciplines, including functional and surgical anatomy of the spine, biomechanics and pathophysiology, diagnostic procedures, and neurology, surgery and outcomes. The aim of "European Spine Journal" is to support the further development of highly innovative spine treatments including but not restricted to surgery and to provide an integrated and balanced view of diagnostic, research and treatment procedures as well as outcomes that will enhance effective collaboration among specialists worldwide. The “European Spine Journal” also participates in education by means of videos, interactive meetings and the endorsement of educative efforts.
