Combining high-resolution micro-computed tomography with material composition to define the quality of bone tissue.
Atraumatic fractures of the skeleton in osteoporotic patients are directly related to a deterioration of bone strength. However, the failure of the bone tissue to withstand functional load bearing cannot be explained as a simple decrease in bone mineral density (quantity); strength is also significantly dependent upon bone quality. While a formal definition of bone quality is somewhat elusive, ...
متن کاملMicro-Computed Tomography for the Evaluation of Bone Architecture
Micro-computed tomography (micro-CT) is an emerging technique for the nondestructive assessment and analysis of the three-dimensional trabecular bone structure. Trabecular bone consists of a complicated three-dimensional network of plates and rods, arranged in a lattice-like network [1]. Aging, disease process, and therapeutic agents could influence the number of elements in this network, their...
متن کاملMicro Computed Tomography Analysis of Magnesium Screw Degradation & Bone Regeneration
INTRODUCTION 6.3 million cases of bone trauma happen each year in the US alone [1]. In a majority of these cases, permanent fixation implants using titanium plates and screws are used as a remedy, but they do have their drawbacks. Some of these disadvantages include bone wear and degradation, resulting in the implant to become loose. They also present a prime site for possible infection [2]. An...
متن کاملContrast Agents for Micro-Computed Tomography of Microdamage in Bone
Accumulation of microdamage during fatigue can lead to increased fracture susceptibilityin bone. Current techniques for imaging microdamage in bone are inherently destructiveand two-dimensional. Therefore, the objective of this study was to image the accumulationof fatigue microdamage in cortical bone using micro-computed tomography (micro-CT)with a barium sulfate (BaSO4) contra...
متن کاملDetection of trabecular bone microdamage by micro-computed tomography.
Microdamage is an important component of bone quality and affects bone remodeling. Improved techniques to assess microdamage without the need for histological sectioning would provide insight into the role of microdamage in trabecular bone strength by allowing the spatial distribution of damage within the trabecular microstructure to be measured. Nineteen cylindrical trabecular bone specimens w...
