Anatomic considerations for safe and effective elbow arthroscopy

Abstract

Due to the complex anatomy and proximity of neurovascular structures, elbow arthroscopy is often perceived as a difficult and potentially intimidating procedure for the nonexpert. A thorough understanding of the elbow anatomy is paramount for safe and effective performance of arthroscopic elbow procedures. Portals are placed in reference to specific anatomic landmarks. The proximity of the ulnar, radial, and median nerves necessitates an understanding of their locations from an intra-articular perspective, and surgeons must make deliberate efforts to protect them during the surgical procedure. Deviations from normal anatomy must be anticipated and scrutinized preoperatively using advanced imaging studies. Careful positioning of the elbow at the time of surgery and selective pen marking of certain anatomic landmarks allow surgeons to progress through the learning curve of elbow arthroscopy.
