Background: The chief source of arterial supply to the palm is provided by association between the superficial palmar branch of radial artery and ulnar artery. Sometimes, there are divergent sources forming the superficial palmar arch and one of them is where there is no arterial supply via radial artery and it is provided entirely by the ulnar artery where the ulnar artery ends by supplying the index finger and thumb. The present study was undertaken to investigate the percentage showing superficial palmar arch formed entirely by ulnar artery.
Materials and Methods: The present study was conducted on 20 hands of unknown sex and age acquired from the Department of Anatomy, Sri Ramachandra Medical College and Research Institute, Chennai. The superficial palmar arch was dissected and the variations are reported.
Results: Out of the 20 hands dissected, 8 hands (40%) showed complete ulnar artery type.
Conclusion: The variations in the pattern of superficial palmar arch will be more significant for anatomists, orthopaedicians, radiologists and trauma care surgeons for micro vascular arterial restorations in cases of inefficient collateral circulation due to ulnar artery occlusions.
KEY WORDS: Superficial Palmar Arch Variation, Radial Artery, Microvascular Surgeries.
