Abstract

Objective: This study focuses on identifying potential complications following oblique lumbar interbody fusion (OLIF) through routine magnetic resonance (MR) scans.

Methods: From 650 patients who underwent OLIF from April 2018 to April 2022, this study included those with MR scans taken 1-week post-operatively, and only for indirect decompression patients. The analysis evaluated postoperative MR images for hematoma, cage insertion angles, and indirect decompression efficiency. Patient demographics, post-operatively symptoms, and complications were also evaluated.

Results: Out of 401 patients enrolled, most underwent 1- or 2-level OLIF. Common findings included approach site hematoma (65.3%) and contralateral psoas hematoma (19%). The caudal level OLIF was related with less orthogonality and deep insertion of cage. Incomplete indirect decompression occurred in 4.66% of cases but did not require additional surgery. Rare but symptomatic complications included remnant disc rupture (four cases, 1%) and synovial cyst rupture (four cases, 1%).

Conclusion: This study has identified potential complications associated with OLIF, including approach site hematoma, contralateral psoas hematoma, cage malposition risk at caudal levels, and radiologically insufficient indirect decompression. Additionally, it highlights rare, yet symptomatic complications such as remnant disc rupture and synovial cyst rupture. These findings contribute insights into the relatively under-explored area of OLIF complications.

OLIF 术后潜在并发症的全面分析:400 多例术后磁共振扫描回顾。
目的:本研究的重点是通过常规磁共振(MR)扫描确定斜行腰椎椎间融合术(OLIF)后的潜在并发症:本研究的重点是通过常规磁共振(MR)扫描确定斜腰椎椎间融合术(OLIF)术后的潜在并发症:从2018年4月至2022年4月接受OLIF的650名患者中,本研究纳入了术后一周进行磁共振扫描的患者,且仅针对间接减压患者。分析评估了术后 MR 图像中的血肿、骨笼插入角度和间接减压效率。此外,还对患者的人口统计学特征、术后症状和并发症进行了评估:在401名入选患者中,大多数接受了1级或2级OLIF手术。常见检查结果包括入路部位血肿(65.3%)和对侧腰肌血肿(19%)。尾椎水平的OLIF与正交性较差和骨笼插入较深有关。4.66%的病例出现不完全间接减压,但无需进行额外手术。罕见但有症状的并发症包括残余椎间盘破裂(4 例,1%)和滑膜囊肿破裂(4 例,1%):本研究发现了与OLIF相关的潜在并发症,包括入路部位血肿、对侧腰肌血肿、尾椎水平的椎笼错位风险以及放射学上的间接减压不足。此外,它还强调了罕见但症状明显的并发症,如残余椎间盘破裂和滑膜囊肿破裂。这些研究结果有助于深入了解 OLIF 并发症这一探索相对不足的领域。

期刊介绍: The Journal of Korean Neurosurgical Society (J Korean Neurosurg Soc) is the official journal of the Korean Neurosurgical Society, and published bimonthly (1st day of January, March, May, July, September, and November). It launched in October 31, 1972 with Volume 1 and Number 1. J Korean Neurosurg Soc aims to allow neurosurgeons from around the world to enrich their knowledge of patient management, education, and clinical or experimental research, and hence their professionalism. This journal publishes Laboratory Investigations, Clinical Articles, Review Articles, Case Reports, Technical Notes, and Letters to the Editor. Our field of interest involves clinical neurosurgery (cerebrovascular disease, neuro-oncology, skull base neurosurgery, spine, pediatric neurosurgery, functional neurosurgery, epilepsy, neuro-trauma, and peripheral nerve disease) and laboratory work in neuroscience.
