“…Parchand and Patil reported complete merging of musculocutaneous nerve into median nerve and branches from median nerve innervated the muscles of anterior compartment instead of musculocutaneous nerve as observed in our study. [5][6][7] Malukar and Rathva also reported the absence of musculocutaneous nerve and its fibres pass through the median nerve. 8 Prasad Rao and Chaudhary reported absence of musculocutaneous nerve in 8% of upper limb specimens.…”

Musculocutaneous nerve arises from lateral cord and supplies the muscles of front of arm and then continues as lateral cutaneous nerve of forearm. Musculocutaneous nerve has frequent variations. Nerve may be doubled or even absent. There is unilateral absence of musculocutaneous nerve in this case. Musculocutaneous nerve arises from lateral cord and supplies the muscles of front of arm and then continues as lateral cutaneous nerve of forearm. Musculocutaneous nerve has frequent variations. Nerve may be doubled or even absent. There is unilateral absence of musculocutaneous nerve in this case. Musculocutaneous nerve was seen to be absent in one case on right side. Branches arise either from lateral cord or median nerve to supply the flexor muscles of arm. Total absent musculocutaneous nerve is quiet uncommon. Hence knowledge of this variation can help clinicians in understanding the cause of weakness or paralysis of flexor muscles of arm due to median nerve injury which is unusual.

“…The variations of the median nerve distributions are concerned to have clinical significance to surgeons, radiologists and anatomists in the injured nerve transfer and brachial plexus surgery. The incidences of unusual formation of median nerve have been documented in populations of Americans (Walsh;Uzun & Seelig, 2001), Slovakians (Haviarova et al, 2001), British (Choi et al), Indians (Chauhan & Roy, 2002;Goyal et al, 2005;Anrkooli et al, 2007;Budhiraja et al, 2009;Saralaya et al;Aggarwal et al, 2010;Datta et al, 2011;Sarala et al, 2011;Budhiraja et al, 2011a,b andParchand & Patil, 2013), Saudi Arabians (Saeed & Rufai, 2003), Egyptians (Beheiry, 2004), Iranians (Anrkooli et al), Portuguese (Pais et al, 2010), Kenyas (Ongeti et al, 2012), and Singaporeans (Parchand & Patil), respectively. The present study is the first report demonstrating the incidence of unusual distribution and concomitant formation of the median nerve in Thai's Thai-Northeast cadavers (Fig.…”

SUMMARY:This study aimed to investigate the incidence of unusual formation of the median nerve in Thai cadavers. Two hundred and ninety-two upper limbs were dissected and observed. The results showed that 5 out of 292 (1.71 %) arms had unusual splitting of median nerve that supplied the flexor arm muscles. Concomitantly, the musculocutaneous nerve was absent. In 4 out of 5 variant arms (80 % or 1.37 % of total upper limbs), each median nerve was unusually formed by 3 roots; the first and second roots were from lateral cord and the third one from medial cord. The union of the second lateral and medial roots to become a median nerve distantly extended in the arm. The second lateral roots gave off small muscular branches to the upper part of flexor arm muscles. Knowledge of such anatomical variations is helpful for surgeons in performing of brachial plexus surgery.

Parchand & Patil (2013) reported that there is a complete merging of musculocutaneous nerve into the median nerve, but the coracobrachialis, biceps and brachialis muscles were innervated by the branches of the median nerve. Prasada Rao & Chaudhary (2001) observed absence of musculocutaneous nerve in 8% of 24 upper limbs.…”

SUMMARY:Variations in the brachial plexus and the distribution patterns of its branches are not uncommon. A communicating branch, which is the most frequent variation, often arises from musculocutaneous nerve to median nerve. However, the branches arising from lateral cord of the brachial plexus and median nerve instead of musculocutaneous nerve are very rare. Detailed description of the abnormalities is important for surgical procedures. Our case study reports the musculocutaneous nerve was absent, a branch from the medial cord innervated the coracobrachialis muscle and two branches from the median nerve innervated the biceps and brachialis muscles, respectively. Moreover, the median nerve gave off the lateral antebrachial cutaneous nerve. This report provides evidence of such possible anatomical variations to surgeons, anesthetists and neurologists during clinical practice.
