Material Properties of Calcifying Costal Cartilage Anthony Lau1, Matthew W. Kindig1, Rich W. Kent1 1University of Virginia ABSTRACT Studies have found that older drivers are more prone to chest injuries in automotive crashes. To characterize the structure and function of articular cartilage and the underlying subchondral bone, micro-computed tomography scans and creep indentation experiments were performed on healthy rabbit specimens. The entire analysis of the cartilage equilibrium response was based on the assumption of isotropic material, which is a very common approach to the confined and unconfined compression tests. The porosity of a sample of cortical bone with no voids would be zero; the porosity of trabecular bone can approach (though not reach) the value 1. These results demonstrate for the first time the effect of changes in articular cartilage properties on the load transmission across a joint. The measurements of contact area described anisotropy of the tissue constituting the superficial zone. It is the nature of the matrix that defines the properties of these connective tissues. Cartilage is a tough, semitransparent, elastic, flexible connective tissue consisting of cartilage cells scattered through a glycoprotein material that is strengthened by collagen fibers. 106 N/m2. 0000001962 00000 n Because of its rigidity, cartilage often serves the purpose of holding tubes open in the body.

The comparison of calculated and measured results reveals how well a specific anisotropy parameter actually describes the mechanical properties of a sample of trabecular bone. eCollection 2018. Would you like email updates of new search results? Due to recent improvements in the spatial resolution of computed tomography, it is now possible to reconstruct the lattice of trabecular bone not only from in vitro bone samples, but also in vivo from tibia and radius (see, for example, Boutroy et al 31). Fig. Found inside – Page 2311EL, and fpeak form a complete set to compare the predictions of the poroelastic finite element model to estimate the intrinsic material properties of cartilage. To test the hypothesis that poroelasticity is the dominant mechanism ... The material properties of the costal cartilage could have affects on the mechanical response of the rib cage. Quantitatively, the modulus of elasticity of trabecular bone ranges between 1.4 MPa and 9800 MPa. In the example shown, we expect long intercept lengths when the grid is oriented vertically and short lengths when the grid is oriented horizontally. Cartilage is a flexible connective tissue that differs from bone in several ways; it is avascular and its microarchitecture is less organized than bone. Collagen: forms a fiber network (defines shape and tensile properties) 2. material properties. [ 19 ]. The matrix dynamic modulus significantly decreased from day 1 through day 60 (P < 0.05). Quantification of in vivo patellofemoral contact forces before and after ACL transection. Abstract--The material properties of normal cadaveric human cartilage in the ankle mortice (tibiotalar articulation) were eval- uated to determine a possible etiologic mechanism of cartilage injury of the ankle when an obvious traumatic episode is not present. METHODS Femoral heads were obtained after surgical removal from age and sex matched groups of patients with either osteoporosis (OP), after a fractured neck of femur, or osteoarthritis (OA) and compared with a normal group.
