Nuff said. A peroneal nerve palsy can be caused by any of a thousand things. After detailing the anatomic basis from which a foot drop can localize, the common etiologies are reviewed in this BrainWaves episode. There are also a few pearls about the interpretation of the needle electromyogram which can help you in the electrophysiologic diagnosis of foot drop.
Our fifth episode to date, it is the first of a series on neuromuscular disease. Other episodes in this series include content on neurologic complications of HIV as well as extra-ocular muscle weakness, both of which have been reviewed on our blog. Definitely worth the 7 minutes it takes to hear.
References. Most of the information was summarized from the highly reputed Preston and Shapiro text, which you can purchase on Amazon here for $150. I highly recommend it for any neurologist, not only those interested in neuromuscular disease. We also reference the Adams and Victor’s Principles of Neurology, which is the neurologist’s equivalent to Isaac Newton’s Principia, for all you nerds out there.
So sit back and relax, but don’t cross your legs. You might get foot drop.
