Posterior interosseous nerve syndrome (PINs) is a rare nerve compression syndrome that affects the deep branch of the radial nerve in the supinator muscle region. In this article, we aimed to report a case of a 58-year-old male who had clinical symptoms, electromyographic, ultrasound, and MRI features suggestive of PINs due to compressing the arcade of Frohse. He subsequently underwent surgical correlation at our hospital, and the clinical symptoms were improved significantly.
