New Techniques in Metabolic Bone Disease

New Techniques in Metabolic Bone Disease presents reviews of the major metabolic bone diseases and the advancement in the techniques used in both research and practice. The text particularly focuses on diagnostic, assessment, and measurement concerns and methodologies such as humoral and local factors affecting bone formation and resorption; photon absorptiometric techniques for measurement of bone mass; and computerized axial tomography scanning. The book will be of great use to both researchers and practitioners of medical fields concerned with bone disease, such as orthopedics.
