The next most common site of compression is at the top of the foot where a small tendon compresses the deep peroneal nerve against the underlying bone. Symptoms here are only sensory, and may feel like a knife sticking in the top of the foot, and pain between the first and second toes. This happens after a crush injury to the foot, wearing tight shoes or tightly laced boots, a broken foot bone, or foot surgery. The treatment is to remove the small tendon and decompress the nerve.
Deep peroneal nerve compression
In the surgical treatment of deep peroneal n. entrapment in the foot, a ligament from the extensor digitorum brevis m. that crosses over the deep peroneal nerve, putting pressure on it and causing pain, is released, as indicated by the dashed lines in the inset to the right.
