Advancements in dynamic reconstruction of the spine have been immense. In particular, arthroplasy of the spine has taken a large step over the last half decade. This book summarizes the current technologies and advancements concerning dynamism. It offers comprehensive coverage of the history of arthroplasty, provides an understanding of current arthroplasty techniques, and proposes a direction for further advancement. This text is divided into various chapters subdivided into four sections. With a thorough review of the cervical and lumbar spine, the text incorporates both anterior and posterior approaches to dynamic stabilization. You will find sections on motion preservation of the spine, lumbar nucleus replacement, lumbar total disc replacement, dynamic posterior stabilization, facet replacement, annular repair, and much more. Within each section, the multitude of different chapters will provide an exhaustive review of systems in proposition and/or production. With each chapter written by the system#s inventor or surgeon with expertise with that particular system, readers will gain specific insights into each system. Finally, dynamic reconstruction of the spine is becoming a reality. This state-of-the-art reference thoroughly summarizes the vast literature and equipment currently being investigated not only to contrast the instrumentation systems but also to provide insight into further research and development.
