How do tissues respond and adapt to stresses around a prosthesis? A primer on finite element stress analysis for orthopaedic surgeons.

摘要: Joint implant design clearly affects long-term outcome. While many designs have been empirically-based, finite element analysis has the potential to identify beneficial and deleterious features prior clinical trials. Finite is a powerful analytic tool allowing computation of stress strain distribution throughout an construct. Whether it useful depends upon assumptions details model. Since ultimate failure related biological factors in addition mechanical, since mechanical causes are load history, rather than few loading conditions, chief among them whether stresses or strains under limited conditions relate Newer approaches can minimize this other model limitations. If surgeon critically properly interpret results scientific articles sales literature, he she must fundamental understanding analysis. We outline here major capabilities analysis, as well
