A method for predicting localized damage and naturally occurring fractures in a subsurface region is provided. This invention uses a hybrid FEM-DEM (i.e. finite-discrete element) framework combined with a fracture risking analysis and fracture initiation and propagation criteria, to model the transition of rock from a state of continuum to discontinuum. The risking analysis combines results from other natural fracture prediction tools (e.g. displacement discontinuity method, restoration analysis, curvature analysis, analytical solutions, continuum analysis) to augment FEM-DEM solutions, such as by providing remote and local boundary conditions and identifying potential regions of anticipated damage and fracturing. Natural fractures and damage information is extracted from the modeling results and may be used directly for predictions or used as input into other fracture analysis tools or techniques. The FEM-DEM and risking techniques can be incorporated into a variety of numerical simulation software packages that use a finite-discrete method solver.

A novel approach for analyzing a patient's body part of interest to assess bone strength and / or risk of future fracture includes obtaining a priori information regarding the body part of interest, performing X-ray absorptiometric scans of the patient's body part of interest and collecting X-ray absorptiometry data from the scans, constructing a three-dimensional model of the patient's body part of interest, by utilizing the a priori information along with the X-ray absorptiometric data, and performing measurements of various geometric parameters on the three-dimensional model for determining geometric and structural properties.

Methods of predicting fracture risk of a patient include: obtaining an image of a bone of the patient; determining one or more bone structure parameters; predicting a fracture line with the bone structure parameter; predicting a fracture load at which a fracture will happen; estimating body habitus of the patient; calculating a peak impact force on the bone when the patient falls; and predicting a fracture risk by calculating the ratio between the peak impact force and the fracture load. Inventive methods also includes determining the effect of a candidate agent on any subject's risk of fracture.

A ceramic-metal composite articulation is provided with substantial elimination of wear debris, wherein a ceramic material is provided with superior mechanical properties tailored for articulating with ceramic articulations having high flexural strength (greater than about 700 MPa), high fracture toughness (greater than about 7 MPam1 / 2) and a high Weibull modulus (greater than about 20), in comparison with presently available bio-ceramics such as alumina or zirconia. The mechanical property enhancement enables ceramic materials with greater reliability and significantly reduced in-vivo fracture risk to be obtained. Preliminary in-vitro wear performance, to several million cycles using established test protocols, of head / cup components in a prosthetic hip joint made from these ceramics also demonstrates the ultra low wear characteristics. These material properties substantially eliminate PE wear debris mediated implant failures by offering an optimal combination of bio-mechanical safety and reliability with ultra low wear performance.

Methods and instruments for assessing bone, for example fracture risk, in a subject in which a test probe is inserted through the skin of the subject so that the test probe contacts the subject's bone and the resistance of the test bone to microscopic fracture by the test probe is determined. Macroscopic bone fracture risk is assessed by measuring the resistance of the bone to microscopic fractures caused by the test probe. The microscopic fractures are so small that they pose negligible health risks. The instrument may also be useful in characterizing other materials, especially if it is necessary to penetrate a layer to get to the material to be characterized.
