“…One is to use intraoperative fascicular nerve stimulation. 30,81 Motor fascicles can be identified, often very precisely, by evoked muscle contractions. In the awake patient, sensory fascicles can be identified and localized by the response of the patient as to whether and where the sensations are felt.…”

Within a peripheral nerve, the individual nerve fibers are grouped together in fascicles. Whether there is somatotopic organization within these fascicles has long been of interest, the subject of many investigations, and somewhat controversial. Evidence from diverse sources now points to important somatotopic clustering of nerve fibers within most of the length of the nerve. Information is lacking regarding proximal segments, particularly the plexus and spinal nerve root levels. As a result of this somatotopic arrangement, partial focal nerve lesions can produce restricted clinical deficits that defy the classic rules of localization. Examples of such restricted nerve lesions are provided in this review. Recognition of fascicle somatotopy is also important in the surgical approach to disorders of peripheral nerves.

“…Intraoperative recording of NAP provides valuable information that helps the surgeon determine not only the location and degree of injury but also the type of surgical repair if needed. Primate studies (Kline et al, 1969) have shown that approximately 4,000 axons are required to elicit a NAP. Hence, incomplete lesions in continuity, where a NAP can be recorded intraoperatively in general, have a good chance of recovery (Kline and Happel, 1993) because of the likelihood of several axons traversing the lesion.…”

The use of intraoperative mapping of neural structures has come to be an indispensable technique to prevent or minimize postoperative morbidity. In this article, I briefly mention its use in mapping nerve roots, plexuses, and peripheral nerves. The reader may find some mention of monitoring techniques, too, as monitoring and mapping are seldom done separately. I include the technical details of different mapping modalities, relevant anatomy, and clinical applications, as appropriate.

“…All the patients had undergone preoperative electromyography examination by means of needle concentric electrode and nerve conduction examinations. In addition to performing electromyography assessment of muscles innervated by the nerves of the brachial plexus, we focused on evaluation of muscles innervated by possible donors for the neurotization procedures [8]. The donors can be divided into two groups.…”

In recent years, brachial plexus injury has been attracting increasing attention, partly because of an increasing incidence arising out of higher survival rates for patients after polytrauma. Brachial plexus injury is one of the hardest and most mutilating injuries. Owing to advances in microsurgical techniques, we can achieve success in restoring motor function for these patients. The purpose of this chapter is to introduce the reader with various microsurgical techniques, including nerve fascicle transfers and end-to-side neurorrhaphy (ETSN), which can be used for brachial plexus reconstruction based on personal experience with 1130 nerve reconstructions performed by the first author (PH) between 1993 and 2017. Another goal of brachial plexus surgery is the resolution of severe intractable pain which can develop in up to 20% of cases. Dorsal root entry zone (DREZ) thermocoagulation is a very effective method for treatment of severe neuropathic pain.
