Peripheral Nerve

Abstract

This chapter addresses the peripheral nerve. The first set of studies discusses the management of carpal tunnel syndrome as well as the treatment for ulnar neuropathy at the elbow, which is the second most common entrapment neuropathy after carpal tunnel syndrome, and it describes lower extremity entrapment neuropathies. The second set of studies examines solitary benign neurofibromas or neurilemomas, which are relatively rare, and considers the international consensus on malignant peripheral nerve sheath tumors in neurofibromatosis 1. The third set of studies assesses the ulnar nerve as an alternative for nerve transfer after complete avulsion of the C5–C6 brachial plexus roots in order to restore elbow function, looks at outcomes of surgery in 1,019 brachial plexus lesions treated at Louisiana State University Health Sciences Center, and evaluates the surgical treatment of brachial plexus birth palsy. The last two studies introduce the application of magnetic resonance neurography in the evaluation of patients with peripheral nerve pathology and propose a five-tiered classification of peripheral nerve injuries.
