Full Answer
Peroneal palsy, a mononeuropathy of the lower extremity, can be debilitating, with symptoms ranging from mild sensory loss to severe, pain, foot drop, and inability to ambulate. Injury to the nerve can be acute or chronic and may result from intrinsic or extrinsic dysfunction.
Common peroneal nerve entrapment is usually due to scar tissue in the region of the common peroneal nerve, which can lead to localized pain, numbness over the anterior and lateral aspects of the leg and foot, and weakness of the foot in dorsiflexion, toe extension, and foot eversion.
The superficial peroneal nerve (superficial fibular nerve) is a mixed nerve that carries sensory information from the anterolateral aspect of the leg and the greater part of the dorsum of the foot (except for the first web space).
The common peroneal nerve is the lateral division of the sciatic nerve. It courses from the posterolateral side of the knee around the biceps femoris tendon and the fibular head to the anterolateral side of the lower leg. Its relationship to the most important landmarks is illustrated on Fig. 1.
The common peroneal nerve, also known as the common fibular nerve, is a major nerve that innervates the lower extremity. As one of the two major branches off the sciatic nerve, it receives fibers from the posterior divisions of L4 through S2.
Common peroneal nerve dysfunction is a type of peripheral neuropathy (nerve damage outside the brain or spinal cord). This condition can affect people of any age. Common peroneal nerve is a type of mononeuropathy.
The fibularis muscles (also called peroneus muscles or peroneals) are a group of muscles in the lower leg.
From its origin, the superficial fibular nerve (L5, S1) descends in the lateral compartment of the leg between the fibularis longus and brevis muscles, and extensor digitorum longus muscle. In the distal third of the leg, the nerve pierces the deep fascia and becomes cutaneous.
Foot. At the junction between the upper two-thirds and lower one-thirds of the leg, the superficial fibular nerve is divided into medial dorsal cutaneous nerve (medial branch) and intermediate dorsal cutaneous nerve (lateral branch).
The common fibular nerve (also known as the common peroneal nerve, external popliteal nerve, or lateral popliteal nerve) is a nerve in the lower leg that provides sensation over the posterolateral part of the leg and the knee joint.
It's a terminal branch of the common peroneal nerve, which itself is a branch of the sciatic nerve. The superficial peroneal nerve contains both motor and sensory fibers, meaning it provides both motion and sensation.
At the malleolar level, the deep peroneal nerve is located between the tendons of extensor hallucis longus and extensor digitorum longus, in close proximity to the dorsalis pedis artery.
