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 radial nerve entrapment,^[2] and is believed to play a role in causing progressive paralysis of the posterior interosseous nerve, both with and without injury. Sensory loss to the region of superficial radial nerve supply is seen along with wrist drop.

The arcade of Frohse was named after German anatomist, Fritz Frohse (1871-1916).
