Background: The superficial palmar arch (SPA) plays a critical role in hand vascularization, with variations in its anatomy having significant implications for surgical procedures. Understanding these variations is essential for optimizing surgical outcomes and minimizing complications. Objective: To investigate the anatomical variations of the superficial palmar arch in cadaveric hands. Methods: This study examined 60 cadaveric hands to categorize the anatomical configurations of the SPA. The types were classified based on arterial contributions and structural patterns. Measurements of the ulnar and radial artery diameters were taken, and variations in the branching patterns of the common palmar digital arteries were noted. Results: The study identified five main types of SPA configurations:Type A (Classical Arch): 32% (19/60) with an anastomosis between the radial and ulnar arteries.Type B (Ulnar Dominant): 27% (16/60) with the ulnar artery solely forming the arch.Type C (Radial Dominant): 15% (9/60) with the radial artery as the primary contributor.Type D (Median Artery Contribution): 13% (8/60) with significant median artery contribution.Type E (Complex Configuration): 13% (8/60) with contributions from the ulnar, radial, and median arteries.The mean diameters of the ulnar and radial arteries were 2.5 mm and 2.2 mm, respectively. The classic branching pattern of common palmar digital arteries was observed in 67% (40/60) of the hands. No significant differences in SPA configurations were found between right and left hands or between genders. Significant median artery contribution was present in 13% (8/60) of cases. Conclusion: This study underscores the variability in SPA anatomy, highlighting the necessity for individualized preoperative assessments in surgical planning to enhance outcomes and reduce complications.
