Anatomical Variations in the Brachial Plexus: Implications for Surgical Interventions

Author(s): Borges Marina*

The brachial plexus is a complex network of nerves that provides motor and sensory innervation to the upper limb. Anatomical variations in the brachial plexus are prevalent and can significantly influence surgical outcomes and strategies. This review article aims to consolidate current knowledge on the anatomical variations of the brachial plexus and their implications for surgical interventions. We provide a comprehensive overview of the common and less frequent variations, including variations in the branching patterns, nerve roots, and their contributions to the formation of the brachial plexus. The review discusses how these variations can impact surgical planning and techniques, particularly in procedures such as brachial plexus reconstruction, shoulder surgery, and trauma management. By examining case studies and recent research, we highlight the clinical significance of understanding these variations to minimize surgical risks and improve patient outcomes. The review concludes with recommendations for preoperative imaging strategies and intraoperative approaches to accommodate brachial plexus variations, emphasizing the need for meticulous anatomical knowledge and individualized surgical planning.
