According to the descriptions in the classical books, brachial plexus is formed by the ventral rami of the cervical nerves (C5, C6, C7, and C8) and the first thoracic nerve (T1). The reported incidence of the brachial plexus variations, which can even differ between the upper extremities of the same person, is 13% and it is most commonly encountered between the median and musculocutaneous nerves. During a routine practice on the brachial plexus of a 65-year old male cadaver, we observed that the musculocutaneous nerve pierced the coracobrachialis muscle after giving the communicating branch in both extremities. According to the recommendation of Buch-Hansen, we decided that the communicating branch was originating from the lateral cord on the right side and from the musculocutaneous nerve on the left side. We detected a second variation after the deepening of the dissection. The media.. Read More»
