Method Dissection was performed in 44 upper extremities (21 right and 23 left) of 24 fixed cadavers used for medical edu cation at Istanbul University, Istanbul Medical Faculty, Department of Anatomy. Results Profunda brachii artery was found to be a single artery in 39 extremities and a double artery in 5 extremities. In 27 cases with single PBA, the nerve was located superolateral to the PBA (Type A), and in 8 cases the nerve was located infero medial to the PBA (Type B). In all 5 extremities with double profunda brachii artery, the proximal branch was superolateral (Type A) and the distal branch was inferomedial (Type B). Conclusions This research will support surgeons understanding how to better anatomically and radiologically treat humeral fractures and lateral arm flap applications.eninfo:eu-repo/semantics/closedAccessProfunda Brachii ArteryRadial NerveRadial GrooveCadaverArticle10.1007/s00276-025-03605-z47117Q3WOS:0014362150000012-s2.0-86000043673PMID: 40029465Q2
