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.

<p>During routine human cadaveric dissection for the purpose of teaching learning of medical undergraduates in our department, third head of the biceps brachii muscle was found bilaterally in a 67 years old male cadaver. Bilaterally symmetrical third head was found with fleshy proximal attachment on humerus between the insertion of the coracobrachialis and the upper part of the origin of the brachialis. This supernumerary head was deep to the other two heads of biceps and was inserted into the bicipital aponeurosis. A branch of musculocutaneous nerve could be traced upto the third head. Long and short heads of biceps were of usual anatomy.</p>

Indirect Injury

The musculocutaneous nerve is rarely injured because it is short and is located deep in the shoulder and arm. Damage is usually caused by direct injuries, including stabbing, explosion, and surgery in a war setting. Although indirect injury of the musculocutaneous nerve is extremely rare, it occurs in various situations. In military parachuting-related activities, musculoskeletal injury occurs most commonly, and static line injury is known as rupture of the biceps brachii tendon. However, musculocutaneous neuropathy can also result from secondary injury by the static line. The musculocutaneous nerve goes together with the biceps brachii muscle, and the musculocutaneous nerve could overstretch and compress within the coracobrachialis muscle where the nerve is relatively fixed due to the overloading of the upper arm with shoulder extension. This report focuses on the indirect musculocutaneous nerve injury with axonotmesis following an overloading event by the static line during military parachuting. In this case, some physicians may confuse nerve injury with static line injury, leading to delays in the diagnosis of neuropathy. If the biceps brachii muscle is damaged due to trauma, checking for the accompanying musculocutaneous nerve injury is necessary.

Different Origins

Anatomical muscles’ variation may face clinician and surgeon with some dilemmas. Obviously, reporting a rare case of variations could explore some unexplained and unexpected clinical symptoms. Bilateral three head biceps, which had a supernumerary head with different origins in both right and left arms, is reported in this case report article. The crucial importance of arm muscles variations’ is because of their adjacent location to brachial nerve plexus and brachial vessels. Every single alteration in the direction of anatomical elements could result in pressure on nerve or vessels with clinical symptoms. Taken together, investigation and popularization of variations make a well-knowledged background for clinicians and surgeons. © 2019 Tehran University of Medical Sciences. All rights reserved.

AbstractThe coracobrachialis muscle (CBM) originates from the apex of the coracoid process, in common with the short head of the biceps brachii muscle, and from the intermuscular septum. The CBM demonstrates variability in both the proximal and distal attachment, with some extremely rare varieties, such as the coracobrachialis superior, coracobrachialis longus and coracocapsularis muscle. This case report describes an extremely rare variant of the coracobrachialis superior muscle, or a very rare variant of the CBM. Our findings highlight the importance of muscle variants in the shoulder region, especially the coracoid region, and are significant for radiologists, anatomists, physiotherapists and surgeons specializing in the shoulder joint.
