Recognizing vascular, muscular, bony, and other nearby non- neural structures helps us identify the target nerve we seek to find. For beginners of nerve sonography, learning to identify relevant sonoanatomy can be quite challenging at the outset and often time consuming if it is self-taught. It is akin to traveling in a foreign land for the first time without a map or navigation aid of any kind. It would be most helpful to be prepared before embarking on a new journey by gathering useful information and directions. This is especially true for ultrasound-guided regional anesthesia as well as many other interventional pain management or diagnostic procedures. This nerve sonography handbook authored by Professors Hannes Gruber, Alexander Loizides, and Bernhard Moriggl, all experts in nerve sonography, is precisely such a helpful aid. One may consider this handbook the Google Maps for nerve sonographers to navigate the world of peripheral nerve sonography. It is a simple, easy-to-follow, reference book with some very cool features – simplicity, landmark-based illustrations, practical tips on scanning, and standardized algorithm for nerve localization. In this handbook, a search of the nerve not only includes a basic nerve compass, it also highlights alternate routes to find the nerve realizing that variation is the rule of human anatomy as Professor Moriggl, the best anatomy and ultra- sound professor I have ever known, so often reminds us. This is a great feature to overcome navigational difficulties by showing sonographic views and screenshots of unfamiliar anatomi- cal terrains. I am confident you will find this one-of-a-kind handbook an invaluable asset to sonogra- phers of musculoskeletal and peripheral nerve anatomy. You will benefit from the authors’ wealth of knowledge, practical scanning advice, and step-by-step nerve localization algorithm. This handbook is easy to understand, concise, and enlightening. Studying this book is a great way to plan and get ready before embarking on a journey of peripheral nerve sonography. As the popular slogan says, “Don’t Leave Home Without It.” Vincent W. S. Chan, MD, FRCPC, FRCA Department of Anesthesia University of Toronto Toronto, ON, Canada v Preface “For whom, and why?” Our target audience and the purpose of this book. This atlas is meant to be a useful “vade mecum” for all colleagues interested and involved in nerve sonography in order to locate nerves as quickly and easily as possible in daily clinical practice. You could put it this way, too: “Never search again for a nerve” – for in this book, you have already found it. Thus, the “Why?” has already been nearly answered since nothing com- parable exists until now. With this book, you will save valuable time, time that most certainly can be better used for a subsequent diagnosis, intervention, and/or therapy. Quite deliberately, this atlas does not contain any information on these latter aspects! Due to the clear descriptions of visible and/or palpable “external” landmarks by illustra- tions and short (!) texts, the ultrasound probe can be placed optimally from the beginning: initial probe positioning. In the ultrasound images, a few but characteristic “internal” land- marks are shown, which help in finding the location and topographic allocation of the “target structure” nerve. As a valuable support for practical application, we, in particular, documented those areas where specific nerves can be delimited best: the respective “point of optimal visi- bility” (POV). Such a point does exist for (nearly) any peripheral nerve! Not without reason, the “POV” does take central position in the overview tables for each single nerve! We are convinced that, especially in cases of unfavorable sonographic conditions, the exact knowl- edge of these POVs can be of decisive help. All this shows that the authors paid very special attention to the practical aspects of nerve sonography. As a result, relevant variations were mentioned, and – if feasible and reasonable – alternative plans were addressed. Additionally, some comments (concerning, e.g., positioning or pitfalls) were enclosed. References to the innumerable studies concerning nerve sonogra- phy, however, were intentionally left out since including them would have conflicted with the intention of this compact manual. We do hope very much that you will be pleased by this atlas and that, above all, it will be used frequently! We should close our introduction with a “quotation” inspired by the famous German author Wilhelm Busch (1832–1908): “You’ll miss a nerve quite easily, if searched for it where it can’t be.” May our book help you to avoid that calamity!
