A Comprehensive Analysis of Potential Complications after OLIF : A Review of Postoperative Magnetic Resonance Scans in Over 400 Cases – Lumbar Fusion

Day Case Lumbar Fusion Surgery

This article discusses a study that aimed to identify potential complications associated with oblique lumbar interbody fusion (OLIF) through routine magnetic resonance (MR) scans. The study included 401 patients who underwent OLIF and analyzed postoperative MR images for hematoma, cage insertion angles, and indirect decompression efficiency. The results showed that common complications included approach site hematoma and contralateral psoas hematoma. The study also found that caudal level OLIF was associated with cage malposition risk and less orthogonality. Incomplete indirect decompression occurred in a small percentage of cases but did not require additional surgery. The study highlights rare but symptomatic complications such as remnant disc rupture and synovial cyst rupture. Overall, these findings contribute to the understanding of OLIF complications, an area that has been relatively under-explored

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 one-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 (4 cases, 1%) and synovial cyst rupture (4 cases, 1%).

: 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.
