During dissection in middle-aged male cadaver, an aberrant radial artery was noticed in the left arm. The artery was taking origin from the upper part of the brachial artery i.e. at a point when axillary artery leaves the axilla and becomes brachial artery.Course of the aberrant vessel was studied in the arm and the forearm. In the upper part of arm the vessel took origin on the lateral side of brachial plexus trunks and traveled to the lateral region of the cubital fossa travelling lateral to the biceps brachii and deep to skin, superficial and deep fascia. In the lower part of the arm i.e. just above the cubital fossa, aberrant vessel was lateral and entered the forearm deep to the pronator teres. Throughout its course the vessel laid superficial to forearm muscles, it was covered by the skin superficial and deep fascia. At the wrist its position was normal i.e. against anterior border of the radius.

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.

AbstractThe coexistence of different muscular-neurovascular variations is of significant clinical importance. A male cadaver, 76 years old at death, was subjected to routine anatomical dissection; the procedure was performed for research and teaching purposes at the Department of Anatomical Dissection and Donation, Medical University of Lodz. The right forearm and hand were dissected using standard techniques according to a strictly specified protocol. The presence accessory head of the flexor pollicis longus may potentially compress the anterior interosseous nerve. The present case report describes a rare variant of the ulnar head of the pronator teres, characterized by two independent bands (i.e., two proximal attachments). The main band originates from the coronoid process and the second originates from the tendon of the biceps brachii. This type of attachment could potentially affect the compression of the ulnar artery running between the two bands. Additionally, the accessory head of the flexor pollicis longus was observed, which started on the medial epicondyle; its coexistence with a high division median nerve creates a potential pressure site on the anterior interesosseous nerve.

El conocimiento de las variaciones en los alrededores de la fosa cubital es útil para cirujanos ortopédicos, cirujanos plásticos y médicos en general. Observamos las variaciones arteriales y musculares en y alrededor de la fosa cubital. La arteria braquial terminó 2 pulgadas por encima de la base de la fosa cubital. Las arterias radiales y cubitales entraron en la fosa cubital  pasando delante de los tendones de los músculos braquial y bíceps braquial respectivamente. La arteria cubital estaba rodeada por el tercer fascículo del pronador teres, que tuvo su origen en la fascia cubriendo la parte distal del músculo braquial. Este músculo se unió a tendón de pronador teres distalmente y fue suministrado por una rama del nervio mediano. Este músculo podría alterar el flujo sanguíneo en la arteria cubital y puede causar dificultades para el registro de la presión sanguínea. Knowledge of variations at and in the surroundings of cubital fossa is useful for the orthopedic surgeons, plastic surgeons and medical practitioners in general. During routine dissection, we observed arterial and muscular variations in and around the cubital fossa. The brachial artery terminated 2 inches above the base of the cubital fossa. The radial and ulnar arteries entered the cubital fossa by passing in front of the tendons of brachialis and biceps brachii respectively. The ulnar artery was surrounded by the third head of pronator teres which took its origin from the fascia covering the distal part of the brachialis muscle. This muscle joined pronator teres tendon distally and was supplied by a branch of median nerve. This muscle could alter the blood flow in the ulnar artery and may cause difficulties in recording the blood pressure.

Object Various donor nerves have been used for brachial plexus neurotization procedures. To the authors' knowledge, neurotization of median nerve branches to the pronator teres to the radial nerve at the elbow have not been explored. Methods In an attempt to identify an additional nerve donor candidate for neurotization procedures of the upper limb, 20 cadaveric upper limbs underwent dissection of the cubital fossa and identification of branches of the median nerve to the pronator teres. Measurements were made of such branches, and distal transection was then performed to determine the appropriate length so that the structure could be brought to the laterally positioned radial nerve via tunneling deep to the biceps brachii muscle. Results All specimens were found to have a median nerve branch to the pronator teres that was long enough to reach the radial nerve in the cubital fossa. Neural connections remained tension free with full pronation and supination. The mean length of these branches to the pronator teres was 3.6 cm. The overall mean diameter of these nerves was 1.5 mm. The mean proximal, midpoint, and distal diameters were 2.0, 1.8, and 1.5 mm, respectively. The mean distance between the origin of these branches to the pronator teres and the medial epicondyle of the humerus was 4.1 cm. Conclusions Based on the results of our cadaveric study, the use of the branch of the median nerve to the pronator teres muscle may be considered for neurotization of the radial nerve in the cubital fossa.

During routine undergraduate dissection in the upper extremities of a 65 years old male cadaver in the department of Anatomy at Dr. PSIMS & RF, coexistence of muscular and neurovascular variants were identified .Muscular variations included presence of additional head(third) of biceps brachii in the left arm, accompanied with medially positioned median nerve in relation to brachial artery bilaterally . Teres minor muscle was not identified and the origin of long head of triceps brachii extended upto the lateral border of scapula on the left side. Both the medial cutaneous nerves of arm and forearm arouse from a single trunk bilaterally. In the right limb the axillary artery showed only four branches instead of six branches, with common trunk for thoraco-acromial and lateral thoracic artery and common trunk for subscapular and posterior circumflex humeral artery. Knowledge of coexistence of these variations would of profound importance surgically and clinically, especially in limb injuries and surgical repairs.

Introduction: Musculocutaneous nerve is derived from the lateral cord of brachial plexus and supplies the muscles of the arm. Initially the nerve accompanies the lateral side of third part of axillary artery and then pierces the coracobrachialis muscle after supplying it, passes downwards and laterally in between biceps brachii and brachialis sending branches to both and continues as lateral cutaneous nerve of the forearm. Variations of musculocutaneous nerve is important for surgeons, orthopedic surgeons and traumatologists, so a detailed cadaveric study of musculocutaneous nerve was done to observe the variations. Material & Methods: Musculocutaneous nerve was studied in 50 human cadavers (30 males and 20 females) of age group 40-60 years at Department of Anatomy, Subharti Medical College, Meerut, India. Results: Musculocutaneous nerve was present in all the cases and was piercing the coracobrachialis muscle. In 4% of the cases, the nerve was rejoining the median nerve after piercing the coracobrachialis.

AbstractVariations in the branching pattern of axillary artery have been observed quite frequently. In a male cadaver aged around 45 years allotted for undergraduate dissection a communicating artery between axillary and radial artery was found on the right side during routine dissection. Such arterial variations are important for clinicians in angiographic examinations, removes ambiguity during diagnostic interventions and surgical procedures. Thereby it ensures competency and reduces complications in cardiac catheterization, pedicle flaps, arterial grafting etc.

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.

Background. This study thoroughly analyzes the anatomic variations of the brachioradial artery (radial artery of high origin) based on the variability of its origin, the presence and types of anastomosis with the brachial artery in the cubital fossa (“cubital crossover” or “cubital connection”), and the pattern of radial recurrent arteries, as well as the vascular territory within the hand. Material and Methods. One hundred and twenty randomly selected, isolated upper limbs fixed in 10% formalin solution were dissected. Results. The radial artery was found to have a high origin in 9.2% of total number of the limbs: two cases from the axillary artery; nine cases from the brachial artery. Anastomosis between the brachioradial and “normal” brachial arteries in the cubital fossa was also frequently observed (54.6%). The anastomosis (“cubital crossover”) was dominant in one case, balanced in three cases, minimal in two cases, and absent in five cases. Conclusions. The brachioradial artery may originate from the brachial and, less frequently, from the axillary artery. Anastomosis between the brachioradial and “normal” brachial arteries in the cubital fossa may be dominant, balanced, minimal, or absent. A complete radioulnar arch was found more often when the brachioradial artery was present as a variant.
