Self-assessment and review of both old and new techniques facilitates comprehensive understanding of principles that underlie spine stabilization biomechanics. edited by renowned spine surgeons Maxwell Boakye, Edward Benzel, Zoher Ghogawala, Darrel S. Brodke, and Jens R. Chapman emphasizes core topics from . First published in 1995, with a third edition in 2015, this widely acclaimed textbook by Edward Benzel is considered the "bible" of biomechanics of spine stabilization.

Organized in nine sections and 39 chapters, this practical learning tool is designed to inform and make biomechanics routinely and practically accessible in clinical spine practice. The book starts with an overview of fundamental concepts, followed by two sections on spine and neural pathology and spine surgery. Sections 4-6 test knowledge of spine instrumentation general principles; regional considerations; and deformity, management, and prevention. Sections 7-8 cover iatrogenic pathologies, the latest spine surgery techniques and technologies, and non-operative spine stabilization. The book concludes with a final section on putting biomechanical concepts into practice.

Key Features

• Written by a who's who of internationally acclaimed spine surgeons and professors
• Systemic chapter layout features brief learning objectives, followed by questions and answers
• Succinct, easily-digestible format provides a quick review, thereby promoting quick acquisition and retention of knowledge

This indispensable resource will help spine residents, fellows, and orthopaedic and neurosurgical spine surgeons better understand clinically important biomechanical principles that underpin spinal surgery and instrumentation, thereby enhancing evidence-based decision making.
