Diagnostic Code 8523 · 38 CFR §4.124a
The deep peroneal nerve controls the muscles that lift your foot upward at the ankle and extend your toes. It also provides a small area of sensation in the web space between your big toe and second toe. When this nerve is damaged, you develop foot drop, meaning your foot slaps the ground when you walk because you cannot lift it properly. You may need a brace to walk safely. Veterans commonly develop this from knee injuries, lower leg fractures, compartment syndrome, crossing legs for prolonged periods during field operations, or direct trauma to the front of the lower leg.
