Protecting nerves is a core part of protecting your patients. This course walks you through the anatomy of peripheral nerves, the Seddon and Sunderland injury classifications, and the real-world mechanisms of stretch, compression, hypoperfusion, and direct trauma that lead to PNI in the OR. You’ll identify key surgical and positioning risk factors, link them to common medico-legal problem areas (like ulnar and brachial plexus injuries), and leave with practical strategies to recognize, prevent, and counsel patients about perioperative nerve injury.
