Abstract
The sciatic nerve is the body's largest peripheral nerve. Along with their two terminal divisions (tibial and fibular), their anatomic location makes them particularly vulnerable to trauma and iatrogenic injuries. A thorough understanding of the functional anatomy is required to adequately localize lesions in this lengthy neural pathway. Proximal disorders of the nerve can be challenging to precisely localize among a range of possibilities including lumbosacral pathology, radiculopathy, or piriformis syndrome. A correct diagnosis is based upon a thorough history and physical examination, which will then appropriately direct adjunctive investigations such as imaging and electrodiagnostic testing. Disorders of the sciatic nerve and its terminal branches are disabling for patients, and expert assessment by rehabilitation professionals is important in limiting their impact. Applying techniques established in the upper extremity, surgical reconstruction of lower extremity nerve dysfunction is rapidly improving and evolving. These new techniques, such as nerve transfers, require electrodiagnostic assessment of both the injured nerve(s) as well as healthy, potential donor nerves as part of a complete neurophysiological examination.
期刊介绍：
The Handbook of Clinical Neurology (HCN) was originally conceived and edited by Pierre Vinken and George Bruyn as a prestigious, multivolume reference work that would cover all the disorders encountered by clinicians and researchers engaged in neurology and allied fields. The first series of the Handbook (Volumes 1-44) was published between 1968 and 1982 and was followed by a second series (Volumes 45-78), guided by the same editors, which concluded in 2002. By that time, the Handbook had come to represent one of the largest scientific works ever published. In 2002, Professors Michael J. Aminoff, François Boller, and Dick F. Swaab took on the responsibility of supervising the third (current) series, the first volumes of which published in 2003. They have designed this series to encompass both clinical neurology and also the basic and clinical neurosciences that are its underpinning. Given the enormity and complexity of the accumulating literature, it is almost impossible to keep abreast of developments in the field, thus providing the raison d''être for the series. The series will thus appeal to clinicians and investigators alike, providing to each an added dimension. Now, more than 140 volumes after it began, the Handbook of Clinical Neurology series has an unparalleled reputation for providing the latest information on fundamental research on the operation of the nervous system in health and disease, comprehensive clinical information on neurological and related disorders, and up-to-date treatment protocols.
