Osteoporosis has been widely known as a reoccurring issue with the increase of age. By understanding key mechanical properties of bone, researchers can better understand methods to induce bone growth as a possible method for osteoporosis reversal. This study uses image modeling to characterize the natural frequency of normal bone by using Finite Element Methods (FEM). Results indicate that the natural...
In this study, the kinematic and dynamic parameters were obtained by using the photogrammetric techniques and three-dimensional force platform in jumping moment for foot, the force and moment acted on the tibia were calculated with inverse dynamics method, the three-dimensional finite element model of tibia that considers material property and geometric behavior was established by CT datum, and stress...
One of the most common spinal fractures is thoracolumbar spine fracture and in this area burst fracture contributed approximately 10%-20% of such spinal problems. The purpose of this study is to investigate biomechanical effects of anterior decompression and posterior instrumentation and evaluate the role of short-segment pedicle screw instrument in order to preservation of adequate spine stability...
A patient's bone status is commonly assessed by radiologic methods. Although the desired information concentrates on the probability of future fractures, the radiologic density is widely used as a surrogate for bone strength. There have been attempts to develop new parameters that have a closer relationship with bone strength, but the investigators tend to use a linear relationship between measured...
