The Complete Medical Guide for Cyclists approaches what it claims to be. If you read the chapters and sub chapters for the book, it does address and describe most of the physiological and anatomical issues faced by the modern cycling enthusiast. As such the Complete Medical Guide for Cyclists does serve as a diagnostic and reference tool for the rider. In clear and concise terms, it outlines injuries and the remedies for them in a logical and easy to follow index.
Find the body part, look for it in the index and then read the chapter that sounds most like what you are experiencing. You will be referred to other sections of the book which describe the proper fit you should have and the remediation measures you should take to rectify the problem. You will also be instructed to visit your local coach, sports medicine facility or better yet to fly out to Boulder.
I love all the sports medicine books I have reviewed from Velopress and I anticipated the same feeling with this one. Alas, this one falls slightly short of full Velopress content. Do not misunderstand, this book is a very thorough listing and diagnostic tool but, by its own admission it is a "first care" edition. Using this book you should be able to define your problem and research it more fully in other publications or use it to determine when it is time to go for actual coaching assistance.
The knowledge and the clarity are all present, what is lacking is the depth. But if you are looking for a quick reference book and diagnostic aid, well then quite possibly this book is the one. I find it more the readers digest condensed guide rather than the Complete Guide it alleges to be.
