This synthesis report will be of interest to officials and staff of municipal, regional, and statewide transportation agencies responsible for roadway design and traffic control. It will be of special interest to those concerned with intersections and driveways on divided highways where larger vehicles encounter narrow medians. It will also be of interest to other professionals who interact with these agencies to mitigate such problems. This report presents state-of-the-practice information about current median design policies and practices, describes the traffic operational and safety problems encountered in designing for larger vehicles at divided highway intersections, and identifies alternative improvement techniques that can be used in new construction or reconstruction projects to avoid introducing traffic operational and safety problems. This TRB report focuses on 10 alternative cross sections widely used on arterial highways in urban, suburban, and rural environment.

This atlas systematically reviews motor conduction studies of the median nerve, from pilot human studies in peripheral nerve conduction during the 1950s through to the most recent scientific evidence. Descriptions are provided of a wealth of motor nerve conduction techniques that were reproduced in the laboratory, including both the originally proposed methods and variants. The techniques are organized according to practical criteria for ease of reference. Attention is focused especially on those techniques which have shown higher sensitivity and specificity in the diagnosis of compressive mononeuropathies like carpal tunnel syndrome (CTS) and on the most widely accepted guidelines, recommendations, quality measures, and electrodiagnostic classifications. The volume is completed with a detailed, well-illustrated glossary explaining the more commonly used terms in electrodiagnostic medicine (EDX). The atlas is primarily intended for residents and professionals in Neurology, as well as rehabilitation physicians and clinical neurophysiologists. The detailed descriptions of techniques and their practical use will also make the book an invaluable tool for novices and clinical neurophysiology technicians.

Practical and user-friendly, this text provides the orthopedic and hand surgeon with all the essential information for diagnosing and treating carpal tunnel syndrome (CTS) and other median neuropathies of the hand and wrist, with special emphasis on challenges and complications. Organized to allow for easy searching of specific subject matter, opening chapters discuss anatomy of the median nerve, history and pathophysiology of CTS, clinical presentation and diagnosis, including imaging, and severity scoring. Presentation of various treatment strategies follows, both non-operative and surgical, including open and endoscopic techniques and revision surgery, incomplete release, transection, use of the reverse radial forearm flap, vein wrap, synovial wrap, and microneurolysis. Other median neuropathies are discussed as well, including neuromas and stimulation for chronic median nerve pain. Generously illustrated, Carpal Tunnel Syndrome and Related Median Neuropathies is a valuable resource for orthopedic and hand surgeons on the evaluation and treatment of complications and complexities arising from carpal tunnel syndrome and surgery.
