Current artificial vertebral disc comprises of the sliding core,… Current artificial vertebral disc comprises of the sliding core, and endplates (see image below). Endplate component loosening and dislocation remain one of the major causes of failure with current design. To better secure the endplate vertebra bone, please use your knowledge to possibly redesign the endplate, especially the fixation mechanism and give detailed rationale to justify your design. In addition, the accurate and precise alignment of sliding core and endplate components is critical for the implantation success. Although various guides for alignment have been designed to improve accuracy, errors still exist most likely due to variations in the bony anatomy, visual misjudgement by the surgeon or limitations of technique. Please identify possible mechanism to help better alignment of the endplates with sliding core and give detailed explanation to this design Image transcription textEndplates: Cobalt-Chromium Alloy coated with commercially pure titanium tri- calcium phosphate layer SlidingCore: ultra high molecular weight polyethylene…   Engineering & Technology Bioengineering BME 505 Share (0)
