Based on the successful format of AO courses, this two-volume reference is a comprehensive manual for the latest AO spine techniques. Principles and Techniques begins with a complete review of basic science concepts, helping the reader understand the biomechanics, biology, and the surgical anatomy of the spine. This volume provides a systematic overview of spinal instrumentation, computer-assisted surgery, and anesthesia considerations. Clinical Applications presents a compilation of clinical cases addressing the most common spinal problems, such as spinal trauma, tumors, infections, inflammatory processes, deformities, degenerative spinal diseases, and metabolic bone disease. For each case, the book guides the reader from case presentation, through rationale for surgical treatment, and to non-operative treatment options. The authors describe potential complications in spine surgery and outcomes. Throughout both volumes, high-quality photographs and drawings illustrate surgical techniques step-by-step and demonstrate key concepts of management. Clear, easy-to-reference bulleted lists and shaded text boxes facilitate rapid review of important learning points. An accompanying DVD-ROM with video clips from live surgery symposia and practical exercises also enhance the reader's learning experience.
