AI Article Synopsis
- Lumbar interbody fusions, used for treating degenerative lumbar disease not responsive to conservative measures, include anterior (ALIF) and posterior (PLIF/TLIF) approaches, but comparative outcome research is limited.
- The study analyzed patient data from the PearlDiver Database between 2010 and 2022, focusing on demographics, comorbidities, and reoperation rates over various timeframes.
- Findings indicated that while posterior fusions had higher reoperation rates and certain complications, anterior fusions are becoming more common, raising questions about the best surgical approach.
Article Abstract
Background: Lumbar interbody fusions are used to treat degenerative lumbar disease unresponsive to conservative treatment. This procedure may be divided into anterior lumbar interbody fusion (ALIF), and posterior lumbar interbody fusion (PLIF/TLIF). Despite their widespread use, comparative research on their outcomes remains limited.
Methods: The PearlDiver Database was utilized to identify patients undergoing single and multi-level ALIF and PLIF/TLIF between 2010 and 2022. We examined demographic data, comorbidities, and reoperation rates at 90 days, 1 year, and 2 years. Complications were assessed using multivariable regression to adjust for confounders.
Results: The study included multi-level anterior interbody fusions (N = 569, mean age 59.8, 59 % female), multi-level posterior interbody fusions (N = 43,651, mean age 57.9, 60 % female), single-level anterior interbody fusions (N = 3,547, mean age 55.3, 61 % female) and single-level posterior interbody fusions (N = 25,792, mean age 56.9, 62 % female). Multi-level posterior interbody fusion patients had a lower prevalence of HTN (OR .77, P < .05), ischemic heart disease (OR .73, P < .05), CDK (OR .77, P < .05), postoperatively more DVTs (OR 1.44, P < .05), a lower incidence of respiratory failure (OR .57, P < .05), and a higher 90-day, 1-year, and 2-year all-cause reoperation rate (7.3 %) compared to multi-level anterior interbody fusion patients (3.7 %). Single-level posterior interbody fusion patients had more HTN (OR 1.1, P < .05), less ischemic heart disease (OR .89, P < .05), obesity (OR .92, P < .05), and postoperatively a higher incidence of DVT (OR 1.34, P < .05) but lower 90-day, 1-year, and 2-year all-cause reoperation rates.
Conclusions: This study confirms that posterior interbody fusions are more common than anterior procedures, though the latter is increasing. Reoperation rates are higher for multi-level posterior and single-level anterior fusions. Both anterior and posterior approaches show similar complication profiles, though specific risks, such as postoperative DVT, vary. These findings emphasize the need for ongoing research and consideration of individual patient factors when choosing an interbody fusion technique.

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).
Indian J Orthop

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.

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.

Objective: This study aims to introduce a two-stage surgical procedure, namely oblique lateral interbody fusion (OLIF), for spinal disorders treatment.
