This atlas, formidable in both size and cost, outlines the use of osteotomy for treatment of coxa vara, femoral neck pseudoarthrosis, and osteoarthritis of the hip. The monograph demonstrates a competence based on a lifetime devoted to a pursuit of exacting techniques. The laudable attempt to present an alternative to the almost universal and automatic use of joint replacement for hip disorders represents a welcome respite. The excellent photographic reproductions and diagrams could have been produced with more efficient use of space. Like too many writers on biomechanics, the author attributes etiology of the various diseases mentioned and their alteration by surgery rather exclusively to biomechanics, to the neglect of the biological factors involved. The volume will be of most value to the specialist in hip surgery who wants to perfect technique as defined by "The Master."
