Background: The blood supply of the hand is complex and challenging. Awareness of the anatomical variationis necessary not only for the anatomist but also for surgeons.The ulnar artery provides a major blood supply to the hand with the assistance of the radial artery in the form of the superficial palmar arch.The objective of this study was reported a rareanatomical variation of the superficial palmar arch.Materials and Methods: The anatomical variation described was found during routine dissection performed by medical students of second semester in a 75-year-old male embalbed adult cadaver in the laboratory of Morphology of the University of Pamplona.Results and Discussion: In the right hand, the superficial palmar arch only gave rise to two common palmar digital arteries. In the left hand, the arch provided common palmar digital arteries which ran into the first, third and the fourth spaces and one proper palmar digital for the little finger. The arch does not supply the second intermetacarpal space.Conclusions: Less critical knowledge of vasculature of the hand might lead iatrogenic injury during surgery, microvascular surgery for revascularization, replantation and composite tissue transfers.Bangladesh Journal of Medical Science Vol.17(3) 2018 p.496-500

Background: The purpose of this paper is to describe an anatomical variation of the hand extensor on the little finger of the right hand which receives four tendons, condition unknown, as it is the first case reported so far in the literature. The human extensor tendons of hand often display an array of variations. Awareness of the anatomy and variations of the extensor tendons on the dorsum of the hand is necessary not only for the anatomist but also for surgeons when considering tendons for hand surgery, tendon rerouting or transplants. Materials and Methods: Bilateral anatomical variation in the upper limb was found during routine dissection in a 75-year-old male cadaver in the Morphology Laboratory at the University of Pamplona. The variations were recorded and photographed. Result: In the left hand the extensor digitorum there was a single tendon to the index, double tendon to the middle, triple tendon to the ring finger, a single tendon to the little finger or digiti minimi. The extensor digiti minimi has double tendon. In the right hand the extensor digitorum there was a single tendon to the index, triple tendon to the middle finger, triple tendons to the ring finger, a double tendon to the little finger. The extensor digiti minimi has double tendon. The little finger receives four tendons, 2 of extensor digitorum and 2 of extensor digiti minimi. The dorsum of the left hand and right showed juncturae tendinum type 2, between the extensors tendons in the 3rd intermetacarpal space; type 3, between the extensors tendons in the 4th inter metacarpal space. Conclusion: The presence of multiple tendons may alter the kinematics around the site of attachment to the phalanx. Knowledge of anatomical variations and normal anatomy of the extensor tendons, may be helpful while performing graft and tendon transfer operations.Bangladesh Journal of Medical Science Vol.15(2) 2016 p.278-282

Among 330 vibration-exposed workers, 24 cases of hypothenar hammer syndrome in 29 hands were diagnosed by arteriography. The right hand was involved in 13, the left hand in six, and both hands in five cases. The mean age was 55 years, mean duration of vibration exposure 19.4 years, and mean duration of episodic Raynaud’s phenomenon 6.4 years. The vascular lesions of the ulnar arteries were classified into three major types with subtypes. Type 1: stenosis of the superficial palmar arch around the hook of the hamate. Type 2a: occlusion of the superficial palmar arch around the hook of the hamate. Type 2b: occlusion of both superficial and deep palmar arches around the hook of the hamate. Type 3a: occlusion of the ulnar artery at the proximal part of the wrist. Type 3b: occlusion of the ulnar artery near the wrist with the occlusion of the dorsal carpal branch of the ulnar artery.

In this paper, we describe a very rare variant in the course of the ulnar artery that we encountered in dissecting the right upper limb of a 74-year-old man. The ulnar artery arose standardly from the brachial artery in the cubital fossa. However, its ensuing course differed from the norm. The artery entered together with the ulnar vein and median nerve into the pronator canal (between the humeral and ulnar heads of the pronator teres). Further, the ulnar artery descended classically to the ulnar side of the forearm between the flexor carpi ulnaris and flexor digitorum superficialis. Knowledge of this variation in the course of the ulnar artery may have significance in clinical practice because accumulation of anatomical structures in the pronator canal could be a predisposing factor for the compression of nerve or blood vessels.

Non recurrent laryngeal nerve is a rare anatomical variation with an incidence in literature of 0.3 % to 1.6 % on the right side. This variation places the nerve at risk of inadvertent injury during head and neck surgeries. Awareness about this abnormality and meticulous dissection of the nerve in every case is the only way to stay safeguarded. Here we present a case of right non recurrent laryngeal nerve in a 32 years old female patient who underwent near total thyroidectomy for nontoxic multi nodular goitre. During surgery, the right recurrent laryngeal nerve could not be identified in its normal location. Further dissection revealed a non recurrent laryngeal nerve arising from the vagal trunk. A CT angiogram was done post operatively and showed an anomalous origin of the right subclavian artery as the last branch of the aortic arch and a bi-carotid trunk. Every surgeon operating on the neck should be aware of and anticipate this variation of the recurrent laryngeal nerve especially when the nerve cannot be identified in the normal location.Bangladesh Journal of Medical Science Vol.15(3) 2016 p.485-487

Introduction: The superficial palmar arch plays a vital role in the blood supply to the hand. The knowledge of variations in the pattern of superficial palmar arch and its branches, and caliber of these arteries, has become more important for surgeons in reconstructive hand surgeries and radial artery harvesting for myocardial revascularization. The aim of this study was to observe the variations and measure the diameter of contributing arteries of the arches. Materials and methods: In the present study, thirty hands from formalin fixed adult human cadavers were dissected. Normal pattern as well as variations in the arteries contributing to the arch, completeness of arch, and the branching pattern were observed and noted. With the help of a digital caliper, the diameters of ulnar and radial arteries and median artery were taken at the level of the wrist and statistical analysis of the results was done. Results: It was observed that in 96.7 % cases, the superficial palmar arch was complete where there was anastomosis between the arteries forming the arch. In 3.3% cases, the arch was incomplete. The complete arch was divided into radioulnar (36.7%), ulnar (56.7%) and medianoulnar (3.3%) types. The diameter of superficial palmar branch of radial artery was found to be significantly less than the diameter of ulnar artery. (p=0.003). Conclusion: The data obtained on variations and morphometry of superficial palmar arches will certainly be useful in planning and choosing appropriate and safe surgical procedures to prevent inadvertent outcome. KEY WORDS: Palmar arch, blood supply, Hand, radial artery, myocardial revascularization.

Arteries in the upper limb play important roles in the circulation system of the human body. In particular, the radial artery has received considerable attention in traditional Chinese medicine for thousands of years. Here, a 3D model for the arm arteries has been created uncomplicated, in a Chinese adult’s left hand, from the magnetic resonance imaging data, using professional modeling software to restore the basic structure of the arm artery in human body, before being imported to Ansys software for simulation. Blood model has been only simulated, and using the blood density of constant parameter and viscosity using the Carreau fluid model, and using viscous-laminar model of Fluent to obtain the velocity profile, static pressure and shear stress in the brachial, interosseous, ulnar, radial and palmar arch arteries. In particular, the brachial and bifurcations have the high pressure and velocity profiles. The simulation results obtained here are also validated by those published in the literature and proved the ulnar artery prevails over the radial artery as a blood supplier to the vessels in the wrist and hand.

Abstract Introduction: Variation of the ulnar artery in the upper limb is uncommon. The existence of such a variant is of particular clinical significance, as these arteries are more susceptible to trauma, and can be easily confused with superficial veins during medical and surgical procedures, potentially leading to iatrogenic distal limb ischemia. Case report: During routine dissection we observed a unilateral case of superficial ulnar artery in a 60-year-old male cadaver. It originated from the left brachial artery in the middle of the arm, near to insertion of coracobrachialis muscle. From its origin, it passed downwards in the medial part of arm behind the median nerve and forearm in a supericial plane compared to normal ulnar artery. In the hand, the supericial ulnar artery anastomosed with the palmar branch of the radial artery, creating the supericial palmar arch. Brachial artery divided into the radial and common interosseous arteries in the cubital fossa. The normal ulnar artery was absent. The existence of superficial ulnar artery is undeniably of interest to the clinicians as well as to the anatomists.

Background: Anatomical structures of head are essential to carry out almost all of dental procedures. In this regard to study the variation of mental and mandibular foramens are prerequisite for the intervention of clinical dentistry. The study was undertaken to determine the anatomical position of the mental foramen (mF) and mandibular foramen (MF) and their relationship.Methods and Methods: Eighty-seven selected Malay patients were examined at Universiti Kebangsaan Malaysia Dental Clinics in which 34 were male and 53 were female. The size and position of the mF in relation to tooth position were recorded. The size and position of the MF were recorded based on the horizontal and vertical dimensions consisting of reference point’s namely anterior and posterior border of ascending border of ramus as well as mandibular notch and lower border of mandibular ramus, respectively.Results: The mF was found to be most in line with second premolar (49%) on both sides in both sexes. The size of mF was larger on the right side and in male (p<0.05). The size of MF on the right and left side for both male and female did not differ significantly (p>0.05). The mean distance between the MF to occlusal plane was 10 mm (SD ±1.56) for both sides. There was no significant difference between mF and MF position (p>0.05).Conclusion: In the Malay population, anatomical relationship and variation between mental and mandibular foramen were not found to be significant. The information would be useful in dental intervention of the clinicians.Bangladesh Journal of Medical Science Vol.15(3) 2016 p.450-454

The Journal's November 1998 issue (57.4:1223) incorrectly identified Paul H. Kratoska's book as Malaya and Singapore During the Chinese Occupation. It should have been cited as Malaya and Singapore During the Japanese Occupation.Due to a production error in the Journal's February 1999 issue (58.1:78–80), the glossary in Joanna F. Handlin Smith's article on “Liberating Animals in Ming-Qing China” lost its original alphabetical order. Thus, Guangci bian is positioned after Chen Di on p. 78; renxing follows “Guang fangsheng hui yin” midway down the first column of p. 79; “Jiesha fangsheng he lun bing wu jue” begins the right hand column on p. 79 and follows Shunzhi at the bottom of the left hand column of that same page; Song Jingwen starts out the first column on p. 80 and follows yinde, the last entry on p. 79, which should have preceded yinguo, the first entry on the right hand column of p. 80.The Journal's February 1999 issue (58.1:269) carried an error.

Background: The veins of the head and neck have a complex developmental pattern which predisposes them to variations in formation and drainage. Superficial veins of the head and neck are utilized for central venous cannulation, oral reconstruction and parenteral nutrition in debilitated patients. Clinical and sonological examinations of these veins may provide clues toward underlying cardiac pathology. Aims: The aim of the present study was to describe anatomical variation and determined the position of the facial vein in relation to neighboring structures. Methods and Findings: Head and neck region were carefully dissected as per standard dissection procedure, studied serially during the years 2013-2017 in 16 males and 2 females, i.e. 36 sides, embalmed adults cadavers with different age group, in the laboratory of Morphology of the University of Pamplona. In 34 sides (94.5 %) of the cases the facial vein (FV) terminated into the internal jugular vein via the common facial vein (CFV) as per standard anatomic description. The facial vein on two sides (5.5 %) was found to drain into the external jugular vein with different degree of angulations and variable distance from the angle of the mandible. On the right side, the facial vein was draining into external jugular vein (EJV), 63.6 mm below the angle of the mandible. On the left side, the facial vein was draining into EJV, 42.4 mm below the angle of the mandible. The length of the neck was 137.8 mm.  The mean distance of the superior and inferior labial veins, deep facial vein, and angular vein from the inferior orbital margin was 41.89 ± 3.01, 52.31 ± 3.72, 26.85 ± 3.55 and 6.25 ± 0.65 mm, respectively. Conclusion: A sound knowledge on variation of the course and termination of facial vein is very useful for oral and maxillofacial surgeons, plastic surgeons, otorrhinologists and radiologists, is essentially important in the clinical examination and surgical procedures of the head and neck region.
