Peroneal nerve paralysis
Peroneal Nerve Paralysis
Peroneal nerve paralysis (pronunciation: puh-ROH-nee-uhl nurv par-uh-LY-sis), also known as foot drop, is a medical condition characterized by the inability to lift the foot at the ankle due to damage to the peroneal nerve.
Etymology
The term "peroneal" is derived from the Greek word "perone", meaning pin or brooch, referring to the fibula bone around which the nerve wraps. "Paralysis" comes from the Greek "paralyein", which means to disable on one side.
Causes
Peroneal nerve paralysis can be caused by a variety of factors, including nerve compression, trauma, neuropathy, and neurological disorders. The peroneal nerve, a branch of the sciatic nerve, is particularly vulnerable to injury due to its superficial location near the skin's surface.
Symptoms
Symptoms of peroneal nerve paralysis include weakness or inability to lift the foot at the ankle (foot drop), numbness on the top of the foot or the outer part of the upper leg, and "slapping" of the foot on the ground while walking.
Diagnosis
Diagnosis of peroneal nerve paralysis typically involves a physical examination, patient history, and may include electromyography (EMG) and nerve conduction studies (NCS) to assess the function of the peroneal nerve.
Treatment
Treatment for peroneal nerve paralysis depends on the underlying cause and may include physical therapy, orthotic devices, and in some cases, surgery.
