Thereof, what is deep peroneal neuropathy?
The peroneal nerve is a branch of the sciatic nerve, which supplies movement and sensation to the lower leg, foot and toes. Common peroneal nerve dysfunction is a type of peripheral neuropathy (damage to nerves outside the brain or spinal cord). This condition can affect people of any age.
One may also ask, what muscles are innervated by peroneal nerve? Deep fibular nerve: Innervates the muscles of the anterior compartment of the leg; tibialis anterior, extensor digitorum longus and extensor hallucis longus. These muscles act to dorsiflex the foot, and extend the digits. It also innervates some intrinsic muscles of the foot.

Common causes of damage to the peroneal nerve include the following: Trauma or injury to the knee. Fracture of the fibula (a bone of the lower leg) Use of a tight plaster cast (or other long-term constriction) of the lower leg.
Is the peroneal nerve sensory or motor?
The common peroneal nerve is a mixed nerve, it contains sensory and motor fibers. The common peroneal nerve arises above the popliteal fossa, runs along the medial edge of the biceps femoris to the neck of the fibula, where it divides into terminal branches: the deep peroneal nerve and the superficial peroneal nerve.
