Introduction: This study focuses on the differences of concomitant single forearm arterial (radial __ampersandsignamp; ulnar) injuries. The ulnar artery has been being consented to be the dominant one of the hand for a long time despite more recent and controversial studies clinical observations might be supporting it. Material and Method: We assessed 108 consecutive, minimum 1-year followed-up, concomitant single artery lacerated forearm injuries operated in our clinic retrospectively, and 38 cases attended. After attendees filled subjective questionnaires, we evaluated their hand circulation, hand sensation, handgrip, pinch-grip, and thermo-distribution. Results: Most common injury type was glass cut (62%), followed by power saw injury (26%). Cases associated with the ulnar artery lacerations were referred to the hospital with significantly (p__ampersandsignlt;0,05) more severe injuries, which appeared to be significantly (p__ampersandsignlt;0,001) associated with the ulnar nerve lesion that appeared to be the most significant (p__ampersandsignlt;0,05) parameter affecting clinical outcomes. Moreover, patency rates for artery repairs were 71% (27/38) similar to the literature and surprisingly, smoking didn__ampersandsignrsquo;t affect arterial patency among our patients (n=22, 57,8% smoker). Conclusion: The ulnar artery is at greater risk due to the most common injury mechanism, and the ulnar nerve associates nearly each ulnar artery laceration and eventuates in certain disability levels. Hence why we are encouraged to consider the medial side of the forearm as strategically valuable and the ulnar artery as the major troublemaker in forearm injuries functionality wise.
