Background: The brachial plexus, a sophisticated network of nerves, plays a pivotal role in clinical anatomy, surgery, and anesthesia, as it is responsible for the motor and sensory innervation of the upper limb. This neural network, which arises from the anterior rami of the C5 to T1 spinal nerves, navigates intricate anatomical regions prior to diverging to innervate the integumentary system and musculature. Aim: To determine the study of brachial plexus anatomical variations in the Indore region variations in its formation, branching, and running. Materials & methods: The study examined the anatomical variations of the brachial plexus in deceased humans, analyzing forty cadavers aged 50-85. It focused on development, branching, and trajectory, and documented variations such as root formation, cable configuration, and nerve trunks. The study also compared conventional descriptions to cadaveric findings. Results: The study found that the frequency of brachial plexus branching mutations was highest in a classic M pattern in 29 out of 80 samples. Other mutations included the common trunk of medial brachial cutaneous nerve, medial antebrachial cutaneous nerve, medial pectoral nerve, thoracodorsal nerve, ulnar nerve and brachial branches, musculocutaneous nerve, and posterior cord giving brachial branches to median nerve. Conclusion: The study of brachial plexus differences in cadaver samples emphasizes the importance of understanding nerve structure differences, which can improve surgical, anesthetic, and rehabilitative practices, aid in precise diagnosis and treatment, and patient care quality.
