Background: The brachial plexus constitutes a complex network of nerves responsible for innervating the upper limb with both motor and sensory signals. This network arises from the spinal nerves located in the cervical and upper thoracic regions. Aim: The aim of this study is to describe the anatomical variations of the brachial plexus in cadavers. Materials & methods: The study examined the brachial plexus anatomy using forty cadavers. It focused on development, branching, and trajectory, using conventional techniques and magnification. The study recorded anatomical differences, including root and trunk formation, cord arrangement, divisions, and additional nerve trunks. Digital photographs were taken for further investigation. The study aimed to identify variations in brachial plexus anatomy and provide insights into ethnic differences. Results: The brachial plexus is found in 92% of specimens, with 8% showing alterations. The construction of trunks is consistent in 90% of cases, with 4% involving a fusion of middle and lower trunks and 6% involving duplicate upper trunks. Divisions are consistent, but asymmetric branching patterns are observed in 7% of cases. The traditional split in the lateral, posterior, and medial cords is found in 88% of specimens. Variations include the absence of a clear medial chord in 6% of cases and an auxiliary lateral cord in 3% of cases. 85% of specimens show typical patterns, with anomalies in 15%, including the absence of the musculocutaneous nerve in 4% of cases and the median nerve developing from three roots instead of two. Notable discoveries include a connecting branch between the ulnar and median nerves in 7% of cases. Conclusion: Cadaveric investigations reveal variations in the brachial plexus anatomy, influencing surgical approaches, anesthetic methods, and treatment in neck, shoulder, and upper limbs, requiring better understanding.
