Anatomic Variations of Brachial Plexus: A Cadaveric Study

introduction: the brachial plexus is responsible for the innervation to the upper limb and someparts of the thorax. variations in the branching of the brachial plexus are common and have beenreported in 65.3% of the population. the variations (atypical communication) of brachial plexushave significant clinical and surgical importance. methods: in this study 10 upper limbs which belonged to 5 adult human cadavers of known sexare used. results: in the present study, three cases (in two cadavers) of 10 cases (in five cadavers) haveconnections between the musculocutaneous and median nerve and seven cases are normal. conclusion: knowledge about the connections between the musculocutaneous nerve and themedian nerve could be very useful in surgical operations on the humerus bone and shoulder joint.so, the more information we could collect about these structures and their variations, the safer thesurgical operations could be done.
