The perforating branches of the posterior interosseous artery are the septocutaneous and musculocutaneous vessels that arise from the posterior interosseous artery as it courses along the dorsal forearm, passing through the intermuscular septum between the extensor carpi ulnaris (ECU) and the extensor digiti minimi (EDM) muscles to supply the overlying skin, subcutaneous tissue, and deep structures.
