Arcade of Frohse
Encyclopedia
Arcade of Frohse, sometimes called the supinator arch, is the most superior part of the superficial layer of the supinator muscle
, and is a fibrous arch over the posterior interosseous nerve
.
The arcade of Frohse is a site of radial nerve entrapment, and is believed to play a role in causing progressive paralysis
of the posterior interosseous nerve, both with and without injury.
The arcade of Frohse was named after German anatomist, Fritz Frohse (1871-1916).

Paralysis
Paralysis is loss of muscle function for one or more muscles. Paralysis can be accompanied by a loss of feeling in the affected area if there is sensory damage as well as motor. A study conducted by the Christopher & Dana Reeve Foundation, suggests that about 1 in 50 people have been diagnosed...
