Lumbar spine or back pain is one of the most important problems in orthopedics and neurosurgery today. Two key ways of treating this malady, lumbar fusion and stabilization, are critically discussed in the forty-three papers in this volume. They represent the best of the contributions to the 5th ICLFS, carefully selected and edited to give a good overview of recent knowledge and the state of the art.

Recent advances in diagnostic technology, including imaging, gene analysis and histopathology, form one cornerstone of this update for health care specialists treating patients with musculoskeletal cancer. The other cornerstone consists of chemotherapy and radiotherapy, as well as highlights in surgical treatment and rehabilitation. The complete structure conveys a systematic understanding of musculoskeletal oncology, with sections on limb saving procedures, reconstruction methods of bone and soft tissues, tumor prosthesis and spinal reconstruction in metastatic bone tumors. All the information is placed under the encompassing goal of total care for the patient.

"Function dictates structure" is a classic paradigm reaffirmed in Wolff's law of the skeletal system. A major question being addressed by current research in biomechanics is whether this doctrine also holds true for the cardiovascular system and connective tissues. Taking a multidisciplinary approach to this question has produced new insights into the sensors, signals, and activators that produce remodeling and functional adaptation in cardiac muscle, blood vessels, and bone, including important new findings on the response of vascular endothelial cells to shear stress. Other work focuses on the extent of remodeling and adaptation processes in tendons, ligaments, and intervertebral discs. Together with two companion volumes, "Computational Biomechanics" and the "Data Book on Mechanical Properties of Living Cells, Tissues, " "and Organs," this monograph will prove invaluable to those working in fields ranging from medical science and clinical medicine to biomedical engineering and applied mechanics.
