Zenker's paralysis
Zenker’s paralysis, also known as peroneal nerve paralysis or palsy, is a paralysis on common fibular nerve that affects patient’s ability to lift the foot at the ankle. The condition was named after Friedrich Albert von Zenker. Peroneal nerve paralysis usually leads to neuromuscular disorder, peroneal nerve injury, or foot drop which can be symptoms of more serious disorders such as nerve compression. The origin of peroneal nerve palsy has been reported to be associated with musculoskeletal injury or isolated nerve traction and compression. Also it has been reported to be mass lesions and metabolic syndromes. Peroneal nerve is most commonly interrupted at the knee and possibly at the joint of hip and ankle. Most studies reported that about 30% of peroneal nerve palsy is followed from knee dislocations.
Peroneal nerve injury occurs when the knee is exposed to various stress. It occurs when the posterolateral corner structure of knee is injured. Relatively tethered location around fibular head, tenuous vascular supply and epineural connective tissues are possible factors that cause damage on the common peroneal nerve. Treatment options for nerve palsy include both operative and non-operative techniques. Initial treatment includes physical therapy and ankle-foot orthosis. Physical therapy mainly focuses on preventing deformation by stretching the posterior ankle capsule. A special brace or splint worn inside the shoe (called an Ankle Foot Orthosis) holds the foot in the best position for walking. Orthosis stretches posterior ankle structures. Physical therapy can help patients to learn how to walk with a foot drop.
==Albert Von Zenker==
Friedrich Albert von Zenker (1825–1898) was a German pathologist and physician, celebrated for his discovery of trichinosis. He was born in Dresden, and was educated in Leipzig and Heidelberg. Attached to the city hospital of Dresden in 1851, he added, in 1855, the duties of professor of pathological anatomy and general pathology in the surgico-medical academy of that city. In 1862 he became professor of pathological anatomy and pharmacology at Erlangen. Three years afterwards he assumed with Ziemssen the editorship of the Deutsches Archiv für klinische Medizin. In 1895 he retired from active service. His important discovery of the danger of trichine dates from 1860. In that year he published "Ueber die Trichinenkrankheit des Menschen" (in volume xviii of Virchow's Archiv). Beside, Zenker also found Zenker's degeneration and Zenker's diverticulum.〔(【引用サイトリンク】title=Whonamedit - Friedrich Albert von Zenker )〕
