Abstract During dissection conducted in an anatomy department of the right upper limb of the cadaver of a 70-year-old male, both origin and course of the radial and ulnar arteries were found to be anomalous. After descending 5.5 cm from the lower border of the teres major, the brachial artery anomalously bifurcated into a radial artery medially and an ulnar artery laterally. In the arm, the ulnar artery lay lateral to the median nerve. It followed a normal course in the forearm. The radial artery was medial to the median nerve in the arm and then, at the level of the medial epicondyle, it crossed from the medial to the lateral side of the forearm, superficial to the flexor muscles. The course of the radial artery was superficial and tortuous throughout the arm and forearm. The variations of radial and ulnar arteries described above were associated with anomalous formation and course of the median nerve in the arm. Knowledge of neurovascular anomalies are important for vascular surgeons and radiologists.

AbstractA case of the abnormal branching of the right Axillary artery in a 60 year old male cadaver is presented here. The axillary artery divided into two trunks, a lateral and medial from the second part only in this case. The lateral branch was superficial running between two roots of median nerve, which here is referred to as superficial branch. The other was a medial trunk, running deep to median nerve on the medial, hence it is referred as deep brachial artery. The superficial branch had a similar course as radial artery coursing on the lateral side of cubital fossa, fore arm, anatomical snuff box and hand, hence it was considered as equivalent to radial artery. The deep brachial artery gave rise to anterior and posterior circumflex humeral arteries and the superior ulnar collateral artery. This variation is rare and the incidence quoted as around 0.12 - 3.2% in the available literature. The normal and abnormal anatomy of the axillary artery is having practical importance for the radiologists during angiography and surgeons for accurate diagnostic interpretation.

Variations of arterial patterns in the upper limb have represented the most common subject of vascular anatomy. Different types of artery branching pattern of the upper limb are very important for orthopedists in angiographic and microvascular surgical practice.The brachial artery (BA) is the most important vessel in the normal vascular anatomy of the upper limb. The classical pattern of the palmar hand region distribution shows the superficial palmar arch. Normally this arch is formed by the superficial branch of the ulnar artery and completed on the lateral side by one of these arteries: the superficial palmar branch of the radial artery, the princeps pollicis artery, the superficial palmar branch of the radial artery or the median artery.After the routine dissection of the right upper limb of an adult male cadaver, we found a very rare variant of the superficial arch artery – a division in a higher level brachial artery. We found this division at 10.4 cm from the beginning of the brachial artery. This superficial brachial artery became a radial artery and was not involved in the formation of the palm arch. In the forearm region, the artery variant was present with the median artery and the ulnar artery, which form the superficial palm arch.

Introduction Bilateral unusual course of the median nerve accompanied with variations of the brachial artery branching pattern are uncommon. Materials and Methods During the routine educational dissection of an upper limb, an interesting neurovascular variation was found in a 45-year-old male cadaver. Results We found a bilateral unusual and variant course of the median nerve in the arm region. The right median nerve, after formation, descended from the medial to the brachial artery, crossed the brachial artery anteriorly from medial to lateral, then inferiorly and lied medially to the distal third of the brachial artery, while the left median nerve ran medial to the brachial artery, passing anteriorly from medial to lateral, and, at the distal end of the arm, it buried itself in the brachialis muscle. Another set of findings were absence of the superior and inferior ulnar collateral arteries, superficial ulnar artery in the forearm and common interosseus artery originated from radial artery. Conclusion These types of compound neurovascular variations are of great importance in orthopedic, vascular, reconstructive surgeries and even in routine nursing care.

AbstractDuring routine dissection of upper limb, a variation in the origin of radial artery was observed in a female cadaver of about 60 years. The radial artery is usually a smaller terminal branch of the brachial artery in the forearm. On the right side of the cadaver the radial artery was found to originate from second part of the axillary artery, whereas on the left side the origin of radial artery was found to be normal. This variant of radial artery has been rarely documented in literature. Accurate anatomy of radial artery and its variations have definite diagnostic, interventional, and surgical significance.

AbstractDuring routine dissection of a cadaver alloted to the undergraduate students in the department of anatomy in SN Medical College, Bagalkot, the authors found multiple variations in the branching pattern of brachial, ulnar and radial arteries. There was high division of brachial artery into ulnar and radial arteries. The profunda brachii originated from brachial artery as usual while superior and inferior ulnar collateral arteries originated from ulnar artery. The radial artery gave origin to common interosseous artery which further divided into anterior and posterior interosseous arteries. All the three arteries i.e. brachial, ulnar and radial were considered as superficial arteries as they were superficial throughout the course. These observations of vascular anomalies are of clinical significance to vascular and plastic surgeons.

The coracobrachialis muscle in the arm is morphologically the sole representative of adductor group muscle in the arm, but such function during the process of evolution became insignificant in man. It is more important morphologically than functionally. Variant insertion of the coracobrachialis muscle was found during routine dissection of an adult male cadaver in the Department of Anatomy, College of Medical Sciences, and Bharatpur, Nepal. Normally the coracobrachialis muscle is inserted into the middle of the medial border of the humerus. In the present case an additional slender tendon passed inferiorly, crossing anterior to the median nerve and brachial artery, before attaching to the medial epicondyle of the humerus. Most of the proximal part of the tendon gave rise to an aponeurotic expansion that inserted into the distal medial border of the humerus. The tendinous insertion and aponeurotic expansion may represent a variant of the coracobrachialis longus (Wood's) muscle and the internal brachial ligament or the ligament of Struthers. The ulnar nerve was found to be traversing below the aponeurotic expansion. This type of anomalous insertion of coracobrachialis muscle may lead to compression of median nerve, brachial artery and ulnar nerve. Key words: Coracobrachialis muscle; ligament of Struthers; median nerve; brachial artery; ulnar nerve.

Background: Variations in upper limb arteries have been frequently observed. Accurate knowledge of muscular and neurovascular variations is important for both surgeons and radiologists, which may prevent diagnostic errors.Methods: A study was done to note the variations in the termination of brachial artery in relation to the level of termination and the terminal branches. A total of 60 upper limbs (33 Right, 27 Left) were studied. The level of termination of brachial artery was identified based on the distance between the intercondylar line and the point of termination. The classic textbook description of brachial artery bifurcating into radial and ulnar arteries, 1 cm distal to elbow joint (ICL) was taken as normal.Results: A high origin of radial artery was noted in 11.67% of cases. Variations in the origin and relationship of median nerve to brachial artery, radial artery and ulnar artery was seen in 4 cases.Conclusions: Due to higher incidence of anatomical variations of arteries of the upper limb, prior anatomical knowledge of anomalies is of great clinical significance to vascular surgeons, orthopaedicians and radiologists performing angiographic studies.

Various aberrant muscles and fibro-tendinous structures have been identified in the anterior wrist, some of them blamed to be possible causes for neurovascular compression syndromes. Herewith, we describe such an intriguing structure related to the flexor carpi ulnaris muscle. During routine dissection of both upper limbs of an adult cadaver, an interesting crescent-shaped fibro-tendinous structure was identified bilaterally, arising broadly from the lateral side of the distal tendon of the flexor carpi ulnaris. This aberrant structure arched over the ulnar artery and nerve before they enter the canal of Guyon and the median nerve just before the carpal tunnel. Further distally, the fibro-tendinous arch narrowed and interlaced with the flexor retinaculum and palmar aponeurosis longitudinal fibres. In this case there was also concomitant bilateral absence of the palmaris longus muscle. Because this aberrant fibro-tendinous arch has very close relations to the median nerve and ulnar nerve and artery in the wrist, it may possibly cause neurovascular compression during some muscle activity.Varios músculos y estructuras fibro-tendinosas aberrantes se han identificado en la parte anterior de la muñeca, muchas de las cuales se considera que pueden causar síndromes de compresión neurovascular. A continuación describimos una tal estructura relacionada con el músculo flexor carpi ulnaris. Durante disecciones de rutina de ambos miembros superiores de cadáveres de adultos fue descubierta una estructura fibro-tendinosa con forma de medialuna en ambos miembros originando de la parte lateral del tendón distal del flexor carpi ulnaris. Esta estructura formaba un arco pasando sobre y cubriendo la arteria y el nervio ulnar antes de que entren en el canal de Guyon, y sobre el nervio mediano justo antes de que entre en el canal carpal. Este arco fibro-tendinoso seguía estrechándose hasta entrelazarse con el ligamento transverso del carpo y las fibras longitudinales de la aponeuorisis palmar .En este mismo caso el músculo palmaris longus estaba ausente en ambas manos. Esta conexión entre el arco fibro-tendinoso y el nervio mediano, la arteria y el nervio ulnar en la muñeca posiblemente puede causar compresión neurovascular durante cierta actividad muscular.

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. Keywords: anatomical variation; median nerve; pronator canal; pronator teres muscle; ulnar artery.
