Project Description

Due to advances in medical technology over the last decade, minimally invasive anterolateral approaches for lumbar interbody fusion have developed significantly. These specific approaches remove the need for disruption of the posterior spinal column, while also allowing wide exposure of the disk space for placement of large interbody grafts.

The purpose of this poster is to provide residents of neurosurgery with a dynamic visual comparison of the three most widely used approaches: anterior lumbar interbody fusion (ALIF), oblique lumbar interbody fusion (OLIF), and lateral lumbar interbody fusion (LLIF). The illustrations depict comparative at risk surgical anatomy/corridors, patient positioning, and key differences between the disk exposures for each approach. Completely understanding the differences between the anterolateral approaches allows neurosurgeons to make better decisions regarding patient selection and surgical techniques, leading to fewer complications and better outcomes.
