The Nanoindentation of Soft Tissue: Current and Developing Approaches
نویسندگان
چکیده
This work is focused on testing biological samples under conditions as close as possible to the natural environment. The data generated can be used to better understand joint damage mechanisms (e.g., osteoarthritis), improve implants, and as a guide for the design of biomimetic materials. Mechanical testing of biological materials is a continuously developing fi eld that requires the testing of hierarchical structures. This article discusses the use of nanoindentation as a valuable tool for assessing multiple length scales as well as parts of complex biological systems. The multiple issues that must be accounted for while testing biological materials are also presented. In addition, dynamic nanoindentation is introduced as a method for testing soft tissues under optimized loading frequencies encountered in everyday movements.

The management of soft tissue defects in tibial fractures is essential for limb preservation. Current techniques are not without complications and may lead to poor functional outcomes. A salvage method is described using three illustrative cases whereby a combination of flaps and antibiotic-impregnated polymethylmethacrylate beads are employed to fill the bony defect, fight the infection, and...

Background and Objective: Different mechanisms may lead to the development of soft tissue tumor-like lesions in the oral cavity. Many of these lesions can be identified as specific entities on the basis of their histopathological features and are divided into fibrous, vascular, and giant cell types. The purpose of this study was to establish the relative prevalence of the different histopath...
متن کاملInvestigation of Shape Functions Role on the Mesh-free Method Application in Soft Tissue Elastography
In current study, The Mesh-free method based on weak-form formulation coupled with the ultrasound imaging technique is developed. This problem consists in computing the deformation of an elastic non-homogenous phantom by numerical methods (both Mesh-free and Finite Element) and converge their results to the measured deformation by the ultrasound. The shape functions of Mesh-free are approximate...

Today, the treatment of patellar luxations using current techniques has become a very common procedureas part of the surgical treatment. Nevertheless, there are some doubts about such procedures in restraining the patella in lower grade cases. The purpose of the present retrospective clinical study was to determine theefficacy of the soft tissue and bone reconstructive procedures used for vario...
