608. The Accessory Obturator Nerve: An Anatomical Study with Relevance to Anterior and Lateral Approaches to the Lumbosacral Spine

Video Transcription

Video Summary

In this video, Matthew Protas, a third-year medical student, presents the findings of an anatomical study on the accessory obturator nerve and its relevance to approaches to the lumbosacral spine. Protas explains the importance of studying this nerve, as previous studies have been ambiguous and only focused on the plexus without considering its actual pathing and innervation. Their 20 cadaver study found that the prevalence of the accessory obturator nerve was around 30%, with variations in origin and sidedness. The nerve was found to be 2-3 centimeters anterolateral to the obturator nerve and innervated the hip joint, pectineus muscle, and anastomosed with the anterior branch of the obturator nerve. The study also discusses the clinical relevance and potential complications related to this nerve.
