THE CLINICAL SIGNIFICANCE OF ACCESSORY BRACHIAL PLEXUS BRANCHES IN TRAUMATIC SHOULDER INJURIES

This study examines the clinical signicance of accessory brachial plexus branches in traumatic shoulder injuries, an often overlooked anatomical consideration in shoulder trauma management. Through a prospective analysis of 124 patients with traumatic shoulder injuries, we identied that 37% presented with variations in brachial plexus anatomy, specically accessory branches. Surgical outcomes and recovery metrics demonstrated statistically signicant differences between patients with recognized and addressed accessory branches versus those with standard anatomical considerations. Electromyographic studies revealed that these accessory branches often maintain functional connectivity even when the primary neural pathways are compromised. Our ndings suggest that identication and preservation of these accessory branches during surgical intervention signicantly improves functional outcomes and reduces persistent neuropathic symptoms. This research highlights the importance of comprehensive preoperative neural mapping and intraoperative neurophysiological monitoring to identify these variations, potentially revolutionizing surgical approaches to traumatic shoulder injuries.
