Lumbar cage design concepts based on additive manufacturing Academic Article in Scopus uri icon

abstract

  • The scope of this work is to present a new design concept for spinal surgery implants based on additive manufacturing. The proposed design concepts for lumbar spaces (or cages) exploit the capacity of the additive manufacturing technologies to generate hollow geometries, facilitating the process of osteointegration. Initial testing and finite element analysis indicates that ABS material is not appropriate for this type of spinal surgery implants. However, it is shown that biomaterials such as polycarbonate (PC) could provide technical feasibility to lumbar cages that provide appropriate strength and osteointegration. © 2014 Taylor & Francis Group.
