Peroneal nerve compression

In the surgical treatment of peroneal nerve compression, an incision is made over the neck of the fibula. (The fibula is indicated by a dashed line beneath the common peroneal nerve and its branches).

Fascia surrounding the nerves to the lateral side of the leg is released. (The fibrous edge of the peroneus longus m. is divided and the muscle is shown slightly pulled away from the nerve at the site of incision).

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.
