“…Median radial type is a very rare type of superficial palmar arch, where the median artery anastomoses with the radial artery and has a minimum or absent contribution of the ulnar artery in SPA. Although, the formation of the SPA by the MA and RA has been mentioned in the literature (Keen 20 1961), only one case was reported in the available literature by Soubhagya R. Nayak 21 …”

BACKGROUNDHands are the most important appendages of human beings. All human hands look alike. But on a detailed study, it can be seen that each and every human hand are unique. Superficial and deep palmar arches form the main feeder of the hand. A classic superficial palmar arch is formed by the superficial branch of the ulnar artery and superficial branch of radial artery. The deep palmar arch is formed by anastomosis of the radial artery with a deep branch of the ulnar artery.The objective of the present study was to study the morphological variations of superficial palmar arch in human. MATERIALS AND METHODS RESULTSThe different types of superficial palmar arches obtained in the present study were as follows: Complete superficial palmar arch (93.33%) [Type A-15 (50%), Type B-10 (33.33%), Type C-1 (3.33%), Type D -0, Type E -0, others-6.66%]: Incomplete superficial palmar arch (6.66%) [Two cases of Type C only]. Median artery forming superficial palmar arch was seen in 16.66% of cases. In addition to this, two variant forms of superficial palmar arches were observed, which were rarely reported in available literature. CONCLUSIONThe present study confirms that the ulnar artery is the dominant vessel, which contributes for the superficial palmar irrigation and the incidence of complete superficial palmar arch is very high compared to the incomplete superficial palmar arch. KEYWORDS BACKGROUNDThe ability of human brain to think, assume, imagine and to dream could be practically projected only to a larger extent with the help of hands. Arterial supply of hand is mainly derived from two anastomotic arches (superficial and deep palmar arches), formed from two terminal branches of brachial artery i.e. radial and ulnar arteries. Variations in the formation of superficial and deep palmar arch are very common. The superficial palmar arch is a dominant arterial arcade present over the palmar aspect of the hand formed by receiving a major contribution from ulnar artery.

“…Since most of its path in the forearm is superficial (RA is often located in the deep to deep fascia), it may be readily accessed for interventional and diagnostic procedures. There is no evidence that the progression of RA is connected to the forearm's neurovascular systems [19][20][21][22] . Because of the hand's UA's collateral blood supply, it may be used for invasive treatments like catheterization and grafting.…”

Background:The cubital fossa lies near the radial artery, a brachial artery terminal branch. Anatomists and physicians' study radial artery branching patterns, origin, and trajectory. Coronary angiography and bypass operations increasingly employ the radial artery. Vascular and plastic surgeons use the superficial and deep palmar arches, Radial artery origin, course, and branches as markers. Methods: The standard dissection technique was used for this. 40 human upper limbs were used for this analysis. The adult upper limb specimens used in this study were taken from embalmed cadavers donated to the Department of Anatomy, Mallareddy Institute of Medical Sciences, Hyderabad, Telangana, India, between the October 2020 to July 2021, for use in the first year MBBS and BDS dissection courses. Results: This study was conducted to document and provide insight into radial artery anatomy both in its normal and variant forms. Subjects were selected from the Medical College and the Institute of Anatomy for the study. There was a fullness to the superficial palmar arch in 80% of people and a lack of perfection in the other 20%. Forty percent of the whole arch was made up of type I arches, 8% of the arches were of type II, and 2% of the arches were of type V. The proportion of type I incomplete arches was 4%, whereas the proportion of type II arches was 16%. Conclusion: Only 6% of people in this research had a radial artery that originated high in the arm from the brachial artery. Overall, radial arteries averaged 21.25 centimetres in length. In 96% and 4% of cases, respectively, the recurrent radial artery originated from the radial artery and the brachial artery. Only around 4% of samples had a recurrent radial artery that was considered an accessory.
