Experimental Techniques to Evaluate in vitro Trabecular Bone Properties and Emerging Numerical Model

摘要

Economical reasons to research and develop new materials are very strong and the main market for biotechnology is human health. Bone is one of the most studied biological material; data and models at different organization levels describe relevant features needed in different applications. Depending on the type of bone, the anatomical location, the human population considered and the level taken into account, the descriptions can differ substantially. In this work, we present a set of properties (mechanical and architectural ones) measured on fresh trabecular bones samples that were extracted from femur heads of live donors with hip total replacement. Standard procedures to preserve the samples were followed. Engineering and clinical tests were performed and custom-built tools were made to adapt the available equipment.
