Arcade of Frohse explained

Arcade of Frohse, sometimes called the supinator arch,^[1] 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 interosseous posterior nerve entrapment,^[2] 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).
