Zusammenfassung: | 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. |
