Role of mechanical factors in the evaluation of pedicle screw type spinal fixation devices|
Goel VK, Ebraheim NA, Biyani A, Rengachary S, Faizan A
Prior to implantation, spinal implants are subjected to rigorous testing to ensure safety and efficacy. A full battery of tests for the devices may include many steps ranging from biocompatibility tests to in vivo animal studies. This paper describes some of the essential tests from a mechanical engineering perspective (e.g., motion, load sharing, bench type tests, and finite element model analyses). These protocols reflect the research experience of the past decade or so.
