Core Tip

Core Tip: Oblique lumbar interbody fusion (OLIF) provides safe retroperitoneal access to nearly all lumbar levels, including L5-S1, thus, allowing single-position surgery. L5-S1 OLIF access may be attempted through three alternative approaches — left intra-bifurcation, left pre-psoas and right pre-psoas approaches — the choice of which can be customized according to the patient’s vascular anatomy.
