Anatomical and Clinical Perspectives on Plexus Brachialis Disorders

This book provides a comprehensive anatomical and clinical overview of plexus brachialis disorders. The brachial plexus is a complex network responsible for motor and sensory innervation of the upper extremity, with diverse clinical presentations depending on the lesion's location within its segmental and topographic organization. It discusses key pathologies including Erb-Duchenne palsy, a birth-related injury affecting the upper trunk (C5-C6 roots), emphasizing the importance of early diagnosis and multidisciplinary management. Thoracic outlet syndrome is described as a complex neurovascular compression syndrome occurring in anatomically narrow cervical-thoracic transition spaces, classified into neurogenic, venous, and arterial subtypes, with each subtype having distinct clinical features and treatment strategies. The text further explores the anatomy and common pathologies of the radial nerve, highlighting entrapment sites, clinical presentations such as wrist drop, and therapeutic approaches. Cubital tunnel syndrome, caused by ulnar nerve compression at the elbow, is summarized as the second most common upper limb entrapment neuropathy with typical sensory and motor symptoms. Finally, carpal tunnel syndrome is detailed as the most frequent entrapment neuropathy involving median nerve compression at the wrist, covering its anatomy, clinical staging, diagnostic methods, and management options from conservative treatment to surgical decompression. The book underscores the necessity of accurate clinical-anatomical correlation, early diagnosis, and integrated therapeutic strategies for optimizing patient outcomes in brachial plexus disorders.
