摘要

研究目的本研究旨在探讨椎体前缘的保留是否会影响使用零型椎体前路颈椎椎间盘切除融合术(ACDF)后的椎体笼下沉和临床疗效:我们回顾性分析了2017年12月至2023年6月期间86例使用零外形钢笼接受1-3级ACDF的患者。根据前缘是否受到保护,将患者分为完整组和缺损组。与术后第2天的测量值相比,随访时椎体高度下降≥2毫米即为Cage下沉。此外,还对患者的放射学参数和临床结果进行了分析:完整组的椎体下沉率为 17.02%(8/47),缺损组为 41.03%(16/39)(P=0.014)。在最后一次随访中,两组患者均实现了完全椎间融合。两组患者的颈椎前凸在术后均得到有效恢复,两组患者的 VAS 和 NDI 评分均有明显改善。多变量逻辑回归分析显示,零轮廓笼下沉的保护因素是椎体前缘的骨保护(OR=0.270,95%CI=0.091-0.804),危险因素与术前手术节段的高度有关(OR=2.285, 95%CI =1.395-3.743):结论:对于使用零轮廓椎体后凸人工关节置换术(ACDF)的患者,尤其是手术节段较高的患者,椎体前缘的骨保护可有效降低零轮廓椎体后凸人工关节置换术的下沉风险,但最终临床效果无差异。

Does Bone Preservation at the Anterior Edge of the Vertebral Body Affect the Subsidence of Zero-Profile Cages After Anterior Cervical Discectomy and Fusion?

Objective: The purpose of this study was to investigate whether the preservation of the anterior edge of the vertebral body affects the cage subsidence and clinical outcomes after anterior cervical discectomy and fusion (ACDF) using zero-profile cages.

Methods: We retrospectively analyzed 86 patients who underwent 1-3 levels of ACDF using zero-profile cages between December 2017 and June 2023. According to whether the anterior edge was protected, the patients were divided into an intact group and a defect group. Cage subsidence was defined as a ≥2 mm decrease in vertebral height at follow-up compared with measurement on postoperative day 2. The patients' radiological parameters and clinical outcomes were also analyzed.

Results: The subsidence rate was 17.02% (8/47) in the intact group and 41.03% (16/39) in the defect group (P = 0.014). At the last follow-up, all patients in both groups achieved complete intervertebral fusion. The cervical lordosis of the 2 groups was effectively restored after surgery, and the visual analog scale and Neck Disability Indexscores of the 2 groups were significantly improved. Multivariate logistic regression analysis showed that the protective factor for zero-profile cage subsidence was bone protection at the anterior edge of the vertebral body (odds ratio = 0.270; 95% confidence interval = 0.091-0.804), and the risk factor was related to the height of the preoperative surgical segment (odds ratio = 2.285; 95% confidence interval = 1.395-3.743).

Conclusions: For patients who undergo ACDF with zero-profile cages, especially those with a higher surgical segment, bone protection at the anterior edge of the vertebral body can effectively reduce the risk of zero-profile cage subsidence, but there is no difference in the final clinical effect.

期刊介绍: World Neurosurgery has an open access mirror journal World Neurosurgery: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. The journal''s mission is to: -To provide a first-class international forum and a 2-way conduit for dialogue that is relevant to neurosurgeons and providers who care for neurosurgery patients. The categories of the exchanged information include clinical and basic science, as well as global information that provide social, political, educational, economic, cultural or societal insights and knowledge that are of significance and relevance to worldwide neurosurgery patient care. -To act as a primary intellectual catalyst for the stimulation of creativity, the creation of new knowledge, and the enhancement of quality neurosurgical care worldwide. -To provide a forum for communication that enriches the lives of all neurosurgeons and their colleagues; and, in so doing, enriches the lives of their patients. Topics to be addressed in World Neurosurgery include: EDUCATION, ECONOMICS, RESEARCH, POLITICS, HISTORY, CULTURE, CLINICAL SCIENCE, LABORATORY SCIENCE, TECHNOLOGY, OPERATIVE TECHNIQUES, CLINICAL IMAGES, VIDEOS
