Introduction: Biceps brachii is one of the functionally important muscles of front of the arm. As the name indicates biceps brachii is having two heads of origin and it inserts on the posterior surface of radial tuberosity. Variations may be present in the form of additional heads of origin or they may be present at its insertion. These variations may affect action of muscle and may cause compression of nearby neurovascular structures. Aim: To determine the variation in anatomy of biceps brachii with respect to its origin, insertion and its nerve supply. Materials and Methods: The present osteological study was conducted on 32 arms of embalmed cadavers (including both right and left) of Department of Anatomy, SRMS IMS, Bareilly, Uttar Pradesh, India from 2015-2018 period. The dissection of arm was done according to standard guidelines and biceps brachii muscle was cleaned. The origin, insertion and nerve supply of biceps brachii muscle was observed and noted for any variation. Results: In the present study an additional head of origin of biceps on right and left side of two cadavers were found. In present study inferomedial origin of biceps brachii was found. The present study also showed the presence of musculotendinous slip at its insertion. This slip was going towards the muscle belly of pronator teres. Conclusion: There are numerous variations seen in biceps brachii which can put a surgeon in dilemma and it may result in iatrogenic injuries. Hence, it is important to have a knowledge about its variations so that such injuries can be prevented.

Introduction Biceps brachii muscle belongs to the flexor group of muscles in arm. As Biceps brachii is double headed muscle. It is one of the known variable muscles of human body in terms of number and morphology. Material and Method During routine human cadaveric dissection for the purpose of teaching medical undergraduates in our department. The upper limb of embalmed adult male cadaver was dissected as per the standard method to note the origin, insertion, and nerve supply of biceps brachii. Results The three headed biceps brachii was found unilaterally on right side in adult male cadaver. The long and short head had normal origin, but third head originated from humerus below insertion of coracobrachialis and inserted with main muscle belly and innervated by musculocutaneus nerve. Conclusion Variant biceps brachii may confuse a surgeon who performs procedures on the arm and may lead to iatrogenic injuries. The surgeons and traumatologists have to keep such muscular variations in mind. So the knowledge of existence of its variation is important for anaesthetists and surgeons.

Background: The biceps brachii is an important muscle of anterior compartment of arm. It shows frequent anatomic variability due to presence of supernumerary heads. Knowledge of the existence of the third head of biceps brachii is important for surgeons. Keeping this in mind a study was planned to see the incidence of additional head of biceps brachii in sample Indian population and to compare it with other racial groups.Methods: The study was carried out on 30 cadaveric upper limbs. The upper limbs were dissected and studied for the presence of additional head of biceps brachii. The attachment and nerve supply of the additional head was carefully observed, recorded and documented.Results: Out of 30 limbs which were dissected, additional head of biceps brachii was found only in two limbs. In both the cases the additional head was present only on the right side and arose from the anterior surface of humerus, superomedial to the origin of brachialis. The additional head fused with the common bulk of the muscle and was inserted into the radial tuberosity and bicipital aponeurosis. The extra heads of biceps brachii muscle received branches from musculocutaneous nerve.Conclusions: Biceps brachii is one of the commonest muscles showing variations. The additional head is not only of academic importance, but its knowledge also helps clinicians in managing fractures of humerus and nerve entrapment.

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.

Closed traumatic disruptions of biceps brachii muscle belly are rarely seen. In this paper, we report two rare cases of biceps brachii muscle belly rupture sustained while water-skiing or wakeboarding and discuss the mechanism of injury, management and outcomes after a literature review. A review of published articles revealed only three previously reported cases of water skiing related biceps muscle rupture. It is important to be vigilant of these injuries, given that early recognition and operative intervention with or without direct muscle repair may optimise outcomes.

A hundred and one right and 109 left dry, fully ossified, human femora have been studied to derive regression formulae for the establishment of the total length of the femur from the length of the lower end taken from the adductor tubercle. The formulae are statistically significant and their validity has been tested on 62 right and 59 left femora. A hundred and fifteen right and 106 left dry, fully ossified radii have been studied to derive regression formulae for establishment of the total length of the radius from the length of the upper end taken to the lower level of insertion of the biceps brachii muscle on the radial tuberosity. The validity of the formulae which are statistically significant has been tested on 51 right and 56 left dry and fully ossified random radii. All the regression formulae have a high degree of prediction, and are valuable in establishing the stature of an individual.

ABSTRACTDuring dissection of a 55-year-old female cadaver, we observed that three nerve roots contributed to the formation of Median nerve in her right upper limb. Along with this variation, absence of Musculocutaneous nerve was noticed. The muscles of front of arm i.e. Biceps Brachii, Brachialis and Coracobrachialis received their nerve supply from Median nerve. The Lateral cutaneous nerve of forearm was derived from Median nerve. Also an accessory head of Biceps Brachii muscle was present in the right arm of the same cadaver. It is extremely important to be aware of these variations while planning a surgery in the region of axilla or arm as these nerves are more liable to be injured during operations.

<bold>Introduction:</bold> Biceps brachii is a large, fusiform muscle of upper limb having two heads of origin; the short head arising by a thick flattened tendon from the apex of the coracoid process Paper Submission Dateand the long head from supraglenoid tubercle of the scapula. The flattened tendon at the lower end rotates as it passes through the cubital fossa to its insertion into the posterior border of tuberosity of the radius. <bold>Case History:</bold> During routine cadaveric dissection of undergraduate teaching program in SRMS IMS, Bareilly,we found rare variation in the insertion of biceps. We observed unilateral Paper Publication Date variation in the insertion of biceps muscle. The biceps tendon at its insertion was divided into July 2016 three distinct parts. Main tendon of long head inserts on radial tuberosity. This tendon of long head sends musculotendinous slip to pronator teres muscle. The short head sends DOI musculotendinous slip to flexor carpi radialis and its tendon does not insert on radial tuberosity despite formation of common belly with long head. The origin of muscle is normal and from two heads – short head and long head. The muscle is supplied by musculocutaneous nerve. <bold>Conclusion:</bold> The triple tendon insertion may allow an element of independent function of each portion of the biceps, and during repair of an avulsion, the surgeon should ensure correct orientation of both tendon components.
