Numerous variations are characteristic for hand anatomy. Although a lot of work has been done in the field, a detailed description of the branches of the radial artery is still missing. Theaim of this study is to determine the incidence and diameter of the accessory artery, which can be found running on the dorsal surface of the interosseus dorsalis primus muscle, to deliver thedetailed description of this arterial variation and based on that to suggest a systematic name of the artery which would be in line with Terminologia Anatomica.
