The increasing adoption of minimally invasive techniques for spine surgery in recent years has led to significant advancements in instrumentation for lumbar interbody fusion. Percutaneous pedicle screw fixation is now a mature technology, but the role of expandable cages is still evolving. The capability to deliver a multiexpandable interbody cage with a large footprint through a narrow surgical cannula represents a significant advancement in spinal surgery technology. The purpose of this report is to describe a multiexpandable lumbar interbody fusion cage, including implant characteristics, intended use, surgical technique, preclinical testing, and early clinical experience. Results to date suggest that the multiexpandable cage allows a less invasive approach to posterior/transforaminal lumbar interbody fusion surgery by minimizing iatrogenic risks associated with static or vertically expanding interbody prostheses while providing immediate vertebral height restoration, restoration of anatomic alignment, and excellent early-term clinical results.

Meta-analysis of minimally invasive transforaminal lumbar interbody fusion versus oblique lumbar interbody fusion for treating lumbar degenerative diseases.
J Orthop Surg Res

Department of Spine Surgery, The First Affiliated Hospital of Guangxi Medical University, 6 Shuangyong Road, Nanning, 530021, Guangxi Zhuang Autonomous Region, China.
Objective: This study aims to perform a meta-analysis that integrates multiple literature sources to evaluate the clinical efficacy of oblique lumbar interbody fusion (OLIF) versus minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) for treating lumbar degenerative diseases (LDD).
Methods: A systematic search was conducted across various databases, including CNKI, VIP, WANFANG DATA, SinoMed, PubMed, Cochrane Library, Embase, and Web of Science, for clinical comparative studies on OLIF and MIS-TLIF for treating LDD, covering the time frame from the inception of the databases to September 2024. Following PRISMA guidelines, studies were screened, assessed, and data were extracted rigorously.
Effect of Approach Based Lumbar Interbody Fusion on Sagittal Spinopelvic Parameters and Functional Outcomes: Comparison between Oblique Lumbar Interbody Fusion (OLIF) and Transforaminal Lumbar Interbody Fusion (TLIF).

Department of Pharmacology, AIl India Institute of Medical Sciences, Bhubaneswar, 751019 India.
Purpose: Transforaminal lumbar interbody fusion (TLIF) and oblique lumbar interbody fusion (OLIF) are the most commonly conducted operations for interbody fusions. In addition to fusion, the restoration of proper spinal alignment has become crucial for achieving favorable functional outcomes. There is a lack of agreement on which lumbar interbody fusion technique provides the most effective correction for sagittal spinopelvic parameters (SSPs).

Study Design: Retrospective cohort study OBJECTIVES: The purpose of this study was to compare the 2-year radiological outcome and revision rates in patients with ASD treated with either PSO or PLIF, when PLIF was used to improve sagittal balance.
Methods: In 2016, PLIF was introduced at our institution as an alternative method when restoring lumbar lordosis. We analyzed two cohorts of patients with ASD undergoing either: PSO in 2010-2015 or PLIF in 2016-2020, retrospectively.

Spine Team, Division of Orthopedic Surgery and Musculoskeletal Trauma Care, Geneva University Hospitals, Faculty of Medecine, University of Geneva, Geneva, Switzerland
Background: Navigation increases the precision and safety of pedicle screw placement and has been used to place interbody cages for lateral lumbar interbody fusion. Single-position surgery shortens its duration and that of anesthesia. The aim of this study was the feasibility of simultaneous cage and screw placement in a single prone position using intraoperative navigation without the need for additional fluoroscopy and a detailed technical description of this procedure.

Department of Orthopaedic Surgery, Beijing Xuanwu Hospital, Beijing, China.
Objective: This study aims to introduce a two-stage surgical procedure, namely oblique lateral interbody fusion (OLIF), for spinal disorders treatment. Furthermore, clinical outcomes and imaging results are analyzed between OLIF with posterior fixation and posterior lumbar interbody fusion (PLIF) with fixation for lumbosacral curve-driven degenerative lumbar scoliosis (DLS).
Methods: 146 patients with type 2 DLS who underwent OLIF or PLIF between January 2019 and November 2023 were included.
