Should a Narrow Corridor Be a Contraindication for Performing Oblique Lateral Interbody Fusion Procedure or Not? – Lumbar Fusion

Day Case Lumbar Fusion Surgery

This article is a retrospective study that investigates the impact of corridor width on the outcomes of patients who underwent the oblique lumbar interbody fusion (OLIF) procedure. The study examined patients who underwent OLIF surgery at the L4-5 level between 2015 and 2021 and divided them into three groups based on corridor width. The study found that there were no significant differences in clinical outcomes, complications, or radiographic findings between the three groups, except for the angle of the cage, which was significantly different in the group with a width wider than 20 mm. The study concludes that the width of the oblique corridor does not affect the outcomes of the OLIF procedure and can be performed safely, even in patients with limited oblique corridors

S: The width of oblique corridor does not affect clinical outcomes, complications, or radiographic findings, including position of the cage, anterior and posterior disc height, segmental angle, and foraminal height after OLIF procedure, including L4-5 level. Thus, the OLIF procedure can be performed safely even in patients with limited oblique corridors, especially at L4-5.

ABSTRACT

STUDY DESIGN: Retrospective study.

OBJECTIVES: We investigated the effect of corridor width on the postoperative outcomes of patients who underwent the OLIF procedure.

METHODS: Patients who underwent OLIF surgery, which included L4-5, between 2015 and 2021 were retrospectively studied. The patients were divided into three groups by the width of the corridor: not more than 10 mm, between 10 and 20 mm, and 20 mm or more. We compared clinical and radiographic outcomes and complications between these groups.

RESULTS: A total of 81 patients were included. There were no significant differences in VAS leg and back pain scores, ODI scores, or complications between each group. The radiographic findings, including cage position, anterior and posterior disc height, segmental Cobb angle, and foraminal height, also showed no significant differences between each group. The only radiographic finding that showed a significant difference between each group was the angle of the cage. We found significantly less degree of angle in the wider than 20 mm group when compared to the other two groups. (P-value = .01). There was no recorded incidence of major vascular complications.

S: The width of oblique corridor does not affect clinical outcomes, complications, or radiographic findings, including position of the cage, anterior and posterior disc height, segmental angle, and foraminal height after OLIF procedure, including L4-5 level. Thus, the OLIF procedure can be performed safely even in patients with limited oblique corridors, especially at L4-5.
