In cases requiring 360-degree fusion or direct decompression, the patient is repositioned to the prone position during surgery, a technique referred to as dual-position LLIF (DP-L). To improve efficiency and eliminate the need for repositioning, surgeons have adopted single-position approaches, completing the entire procedure either in the lateral decubitus or prone position. This explores the advancements in LLIF and single-position LLIF. Comparing both single position lateral decubitus LLIF and single position prone (P-SPS) to the traditional DP-L. A narrative review of the literature on single-position surgery (SPS) LLIF was conducted to provide an overview of its key aspects and clinical applications. The review included studies comparing SPS lateral and SPS prone to DP-L, encompassing systematic reviews, meta-analyses, retrospective studies, and case series. Additional studies deemed relevant for a thorough review were also included. No randomized controlled trials were identified or included in this review. Lateral single-position surgery and P-SPS have shown reductions in operative times and hospital length of stay compared with DP LLIF. In addition, both techniques improved estimated blood loss, complication rates, and radiographic outcomes. However, the statistical significance of these findings varied inconsistently across the published studies. The development of LLIF represents a notable advancement in spine surgery. SPS builds on this foundation, offering potential improvements over the original technique. While SPS has demonstrated certain advantages, there remains room for further refinement and optimization in its application.</p>","PeriodicalId":19276,"journal":{"name":"Neurosurgery","volume":"96 3S","pages":"S9-S16"},"PeriodicalIF":3.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143414846","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the American Association of Neurological Surgeons/Congress of Neurological Surgeons Section on Tumors marks its 40th anniversary in 2024, this article reflects on the tumor guidelines established by the Section over the past decade and explores their impact on other publications, patents, and information dissemination. Six tumor guideline categories were reviewed: low-grade glioma, newly diagnosed glioblastoma, progressive glioblastoma, metastatic brain tumors, vestibular schwannoma, and pituitary adenomas. Citation data were collected from Google Scholar and PubMed. Further online statistics, such as social media reach, and features in policy, news, and patents were sourced from Altmetric. Online engagement was assessed through website and CNS+ mobile application visits. Data were normalized to time since publication. Metastatic Tumor guidelines (2019) had the highest PubMed citation rate at 26.1 per year and webpage visits (29 100 page views 1/1/2019-9/30/2023). Notably, this guideline had two endorsement publications by partner societies, the Society of Neuro-Oncology and American Society of Clinical Oncology, concerning antiepileptic prophylaxis and steroid use, and the greatest reach on X (19.7 mentions/y). Citation rates on Google Scholar were led by Vestibular Schwannoma (2018). Non-Functioning Pituitary Adenoma led Mendeley reads. News, patent, or policy publications were led by low-grade glioma at 1.5/year.
