Patient selection and workup

Abstract

Patient selection is vital to achieve success in the Anterior-to-Psoas (ATP) / Oblique Lateral Interbody Fusion (OLIF) approach. This technique, which offers unique advantages, can be technically demanding and requires careful preoperative evaluation to optimize outcomes and minimize complications. This article aims to guide surgeons in identifying suitable patients, perform a thorough patient workup and address the unique challenges associated with the ATP/OLIF procedure. In particular we discuss anatomical variations seen on imaging as well as important features in the patient history and examination. Through optimizing patients preoperatively and building a surgical plan for the individual's anatomy, the surgeon can minimize risks and improve patient's outcomes.
