Nerves Anatomy and Electrophysiology for Orthopaedic Exams

Description

The webinar on nerve physiology and neuroanatomy, led by David Hughes, covers complex topics essential for medical exams. David starts the session by welcoming attendees and acknowledging the support of Sichuan and senior mentors behind the scenes. He introduces the subject matter—nerves and neurophysiology—and emphasizes the significance of understanding nerve injuries, their classifications, and repair mechanisms. Housekeeping notes encourage participants to engage through chat or by raising hands for questions, especially regarding the viva segment.



As David progresses, he discusses the anatomy of nerves, stressing the importance of distinguishing between sensory and motor functions, and outlines how to draw a nerve structure accurately. The speaker further illustrates different conditions of nerve damage, including neuropraxia and axonotmesis, and dives into the practical aspects of nerve conduction studies (NCS) and electromyography (EMG).



David provides a detailed explanation of how NCS measures the speed and amplitude of electrical impulses along nerves, pointing out the relevance of these metrics in diagnosing peripheral nerve injuries. He also answers questions on clinical scenarios where such studies are applicable, especially for conditions like carpal tunnel syndrome and brachial plexus injuries. The importance of familiarity with various terms and concepts related to nerve physiology is highlighted, guiding participants to better prepare for exams and clinical practice.
