Meet the challenges and demands facing professionals in the dynamic field of spinal implants. Twenty-one peer-reviewed papers give you a global perspective on current and future testing methods. They address the relationship between existing standards and clinical experience; suggestions for areas of change; and the development of standards for emerging technologies of spinal implants. Sections cover: Spinal Constructs; Spinal Device Compenents, Subassemblies, and Interconnections; Interbody Spacers and Intervertebral Body Fusion Devices; Functional Spinal Devices and/or Artificial Discs; Suggested Test Methods, Models, Fixtures, or Needed Improvements.
