Abstract

Study design: Retrospective cross-sectional study.

Purpose: To investigate the size and local anatomy of the right and the left-sided oblique corridors between L1-L5 levels and identify the potential impact of increasing age and sex on corridor size.

Overview of literature: The oblique lumbar interbody fusion (OLIF) was introduced by Silvestre and his colleagues as a solution to the approach-related complications associated with anterior lumbar interbody fusion and lateral lumbar interbody fusion. Limited data were available describing the local anatomy and morphology of this approach.

Methods: Imaging data of 300 patients (150 males and 150 females) who underwent 1.5T magnetic resonance imaging (MRI) scans of the lumbar spine at Indian Spinal Injuries Centre, New Delhi, India between January 2023 and January 2024 were retrospectively reviewed. The cohort was stratified into six age groups (21-30, 31-40, 41-50, 51-60, 61-70, and >70 years) with 25 patients in each age group for both sexes. T2 weighted axial MRI images were analyzed from the L1-L5 level at the mid-disc level to calculate the corridor size. The local anatomical differences were recorded.

Results: At L1-L2, L2-L3, L3-L4, and L4-L5 levels, the mean corridor sizes in males were 17.48, 15.50, 13.41, and 9.32 mm on the left side, and 11.48, 7.12, 4.34, and 1.64 mm on the right side, respectively. The corresponding mean corridor sizes in females were 10.34, 12.94, 12.64, and 7.22 mm on the left side and 2.66, 3.52, 3.69, and 1.64 mm on the right side, respectively. For both sides, the corridor size was significantly affected by sex, increased with age, and decreased at the lower lumbar disc levels.

Conclusions: A left-sided OLIF approach is more feasible for both sexes. The right-sided approach is less likely to be performed effectively.

基于磁共振成像的双侧 L1-L5 斜腰椎椎间融合走廊形态计量分析:安全手术方法的可行性及影响因素。
研究设计目的:研究 L1-L5 水平之间右侧和左侧斜行走廊的大小和局部解剖结构,并确定年龄和性别增长对走廊大小的潜在影响:斜行腰椎椎体间融合术(OLIF)是由 Silvestre 及其同事提出的,旨在解决与前路腰椎椎体间融合术和侧路腰椎椎体间融合术相关的并发症。描述这种方法局部解剖和形态的数据有限:回顾性分析了 2023 年 1 月至 2024 年 1 月期间在印度新德里印度脊柱损伤中心接受腰椎 1.5T 磁共振成像(MRI)扫描的 300 名患者(150 名男性和 150 名女性)的成像数据。研究对象分为六个年龄组(21-30 岁、31-40 岁、41-50 岁、51-60 岁、61-70 岁和大于 70 岁),每个年龄组有 25 名男女患者。从 L1-L5 椎间盘中段水平分析 T2 加权轴向 MRI 图像,计算走廊大小。记录局部解剖学差异:结果:在 L1-L2、L2-L3、L3-L4 和 L4-L5 水平,男性左侧走廊的平均尺寸分别为 17.48、15.50、13.41 和 9.32 毫米,右侧分别为 11.48、7.12、4.34 和 1.64 毫米。女性的相应平均走廊尺寸在左侧分别为 10.34、12.94、12.64 和 7.22 毫米,在右侧分别为 2.66、3.52、3.69 和 1.64 毫米。两侧的走廊大小受性别影响明显,随年龄增长而增大,在腰椎间盘水平较低时减小:结论:左侧 OLIF 方法对男女患者都更可行。结论:左侧 OLIF 方法对男女患者都更可行,而右侧方法的有效率较低。
