Arcade of Frohse

Arcade of Frohse

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 the most frequent site of posterior interosseous 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).
