Abstract

Introduction: The traditional definition of superficial palmar arch consists of linkage between the superficial palmar branches of the radial and ulnar arteries. But it is interesting to know that this is not always the most commonly observed morphology. In the present study, the objective was to study the morphological variants of the superficial palmar arch in humans and to discuss their clinical implications. Material and methods: The study included 48 hands from the adult human cadavers. All the cadavers were available at the department of anatomy and fixed with 10% formalin solution. The morphology of the superficial palmar arch was studied in all the hands and the variations were noted. Results: Among our specimens, 45 (93.75%) hands had the usual morphology of the superficial palmar arch and the variant morphological patterns were observed in only 3 (6.25%) hands. In one of the hands, there was absence of formation of the arch; the other hand had the arch which was formed only by the ulnar artery. The third case though the arch was formed by the anastomosis between ulnar and radial arteries, showed the variation in its branching pattern. Conclusion: The present study had provided details about some of the morphological variants of superficial palmar arch in humans which will be enlightening for the operating hand surgeons and orthopedicians. Recent advances in the microsurgical techniques for reconstructive hand surgeries have necessitated the understanding of variant arterial arches, the comprehensive knowledge of which is important for the surgical interventions and successful outcome.
