Abstract

In this case report, we want to present a truly incomplete superficial palmar arch on right side which is not completed by any of the branches of radial or median artery. On the left side of the same individual, the SPA is classical, completed by superficial branch of radial artery. The areria nervi mediana is not participating in arch formation on both the sides. Four palmar digital branches: digital branch to medial side of little finger and three common palmar digital arteries to the adjacent sides of medial four digits are seen arising from incomplete palmar arch. Awareness of the variation among the individual patient’s both hands need to be well thought-out during hand surgeries.
