Benign Peripheral Nerve Tumors
Types and Nomenclature Different types of PNT can present different characteristics. BPNST are more commonly reported than nonneurogenic masses. 9, 10, 11 In this chapter, we will discuss the subtypes…
Electrodiagnostic Pre-, Intra-, and Postoperative Evaluations
Anatomical Characteristics Axons are extensions of neuronal cell bodies. They transmit nerve impulses and are enveloped by myelin. Myelin is produced by Schwann’s cells (SCs) in the peripheral nervous system…
Traumatic Brachial Plexus Lesions: Clinical Aspects, Assessment, and Timing of Surgical Repair
Types and Mechanisms of Injury The typical patient with a brachial plexus injury is a young man involved in a motorcycle accident. Although his helmet in many cases saves his…
Compressive Lesions of the Lower Limb and Trunk
Sciatic Nerve General Considerations Being the largest nerve in the body, the sciatic nerve usually consists of L4–S3 contributions. After its intrapelvic course in the vicinity of the sacrum, the…
Magnetic Resonance Neurography and Peripheral Nerve Surgery
Fig. 7.1 Normal median nerve within the carpal tunnel. On axial T1w (a), it is isointense to muscle (flexor carpi ulnaris, asterisk) and exhibits a fascicular appearance; on STIR (b), it…
The Neonatal Brachial Plexus Lesion: Surgical Strategies

Thoracic Outlet Syndrome
The syndrome can be divided grossly into vascular TOS and neurogenic TOS (NTOS). The vascular form can target the subclavian artery, causing distal ischemia, or the subclavian vein, characterized by…
Surgical Repair of Nerve Lesions: Neurolysis and Neurorrhaphy with Grafts or Tubes
Evaluation and Approach A thorough understanding of the nerve injury is imperative following a clinical diagnosis. This is because subsequent management strategies are strongly based on the type of insult…
Nerve Injuries: Anatomy, Pathophysiology, and Classification
Fig. 3.1 (a) Schematic drawing of the basic structure of normal peripheral nerves. (b) The essential elements of the three layers of peripheral nerves. Nerves are subjected to trauma by many…
