Lateral Fusion is a Unique Feature in Oblique Lumbar Interbody Fusion Surgery: A Retrospective Cohort Study.

ABSTRACT:

Study design

Retrospective cohort study.

Objective

Limited clinical literature addresses potential differences in fusion features between Oblique lumbar interbody fusion (OLIF) and transforaminal lumbar interbody fusion (TLIF). We observed that in OLIF, there are many cases with the appearance of extra-vertebral bone bridges (EVB), a phenomenon distinct from traditional TLIF fusion. This study aims to compare fusion rates, cage subsidence, and fusion features among OLIF stand-alone (OLIF-SA), OLIF with posterior pedicle screw fixation (OLIF-PS), and TLIF.

Methods

We retrospectively analyzed 198 patients (311 levels) undergoing OLIF-SA, OLIF-PS, or TLIF from July 2017 to June 2021. We assessed patient-reported outcomes, cage subsidence, fusion rate, and fusion features
