Effects of trabecular type and orientation on microdamage susceptibility in trabecular bone [PDF]
Bone, 2010 Trabecular architecture becomes more rod-like and anisotropic in osteoporotic and aging trabecular bone. In order to address the effects of trabecular type and orientation on trabecular bone damage mechanics, microstructural finite element modeling was used to identify the yielded tissue in ten bovine tibial trabecular bone samples compressed to 1.2 ...

Effect of trabecular curvature on the stiffness of trabecular bone
Journal of Biomechanics, 2005Simplified structural models of trabecular bone have been used to model various forms of trabecular variability. The structural effects of variability of direction, length and thickness of the trabeculae have been studied using 'lattice-type' finite element models.

Biomechanics of Trabecular Bone
Annual Review of Biomedical Engineering, 2001Trabecular bone is a complex material with substantial heterogeneity. Its elastic and strength properties vary widely across anatomic sites, and with aging and disease. Although these properties depend very much on density, the role of architecture and tissue material properties remain uncertain.

This study was conducted to evaluate the theory that increased rigidity in the subchondral cancellous bone and trabecular stress fractures are responsible for the development of osteoarthritis. Histological sections of the entire femoral head were examined in 80 normals, 50 cases with early degenerative changes, and 50 cases with advanced ...

The Trabecular Anatomy of the Axis
Spine, 1993This article describes the internal anatomy of C2. Although some C2 specimens showed a high density of trabecular bone throughout, a feature noted in all specimens was a void or very hypodense area of bone located immediately beneath the dens. The observed nonuniform distribution of trabecular bone within the axis is considered to have an effect on ...

Healing trabecular microfractures are a common feature in cancellous bone. These lesions, when observed in macerated cancellous bone slices, measure about 500 microns in diameter and surround fractures in trabeculae with microcallus. Whether microcallus is a structure acting primarily as a transient brace, preventing relative movement of the fragmented

Trabecular mapping: Leveraging geometric morphometrics for analyses of trabecular structure
American Journal of Physical Anthropology, 2017AbstractObjectivesTrabecular microstructure of limb bone epiphyses has been used to elucidate the relationship between skeletal form and behavior among mammals. Such studies have often relied on the analysis of a single volume of interest (VOI). Here we present a method for evaluating variation in bone microstructure across articular surfaces by ...

Interrelationship of trabecular mechanical and microstructural properties in sheep trabecular bone
Journal of Biomechanics, 2005The ability to evaluate fracture risk at an early time point is essential for improved prognostics as well as enhanced treatment in cases of bone loss such as from osteoporosis. Improving the diagnostic ability is inherent upon both high-resolution non-invasive imaging, and a thorough understanding of how the derived indices of structure and density ...

Antiglaucomatous trabecular surgery
Current Opinion in Ophthalmology, 1997In contrast to conventional filtering procedures, microtrabecular surgery is intended to selectively combat the diseased structure in the pathogenesis of chronic open-angle glaucoma, thereby reducing potential risks during and after transscleral drainage operations.

Trabecular Carcinoma of the Skin
Archives of Dermatology, 1972Five patients had trabecular carcinomas of the skin. The growths originate within the dermis or in the immediate subcutis, and display a uniform morphology. They are composed of solid trabeculae that lack definite acini. A derivation from cells that are capable of reproducing primitive sudoriferous structures is postulated.
