The foot often acts as a vital indicator of internal disorders. In addition, its careful examination can point to problems in other parts of the body. This atlas not only diagnoses conditions affecting the foot and lower limb, but also demonstrates approaches for examining the foot that may lead to the diagnosis of systemic disease. Differential diagnosis is included as well as examples for normal variations. The authors offer a collection of foot pictures organized in a variety of ways - by diagnosis, by specific disease-related problems and by normal variations. Troughout, the reader is encouraged to recognize the normal as a basis for understanding the abnormal.
