Collecting and synthesizing all of the most recent literature on Kienböck s disease from around the world, this comprehensive text aims to provide a more dynamic, nuanced treatment algorithm for this enigmatic condition. Part I consolidates the basic science on Kienböck s and the lunate, including anatomy, pathology, biomechanics and etiology. Clinical assessment is covered in part II, including radiology, advanced imaging and arthroscopy. The natural history and progression of the condition in children, adults and the elderly is also presented. By far the largest section, part III describes the roles and methods of the various management strategies for Kienböck s, from minimally invasive techniques to arthroscopic and arthroplastic procedures.  The final chapter draws from all of these concepts, establishes a new algorithm and provides a direction for the future.
