In the field of orthopedics, this technique has predominantly been used for implant design and testing. As the technology improves, increasing clinical applications are being developed, offering promise in the areas of surgical planning and the opportunity to tailor implants to individual patient characteristics. This article introduces the various preclinical mechanical tests available, as well as providing a brief overview of the finite element analysis technology.
