Osteoporotic patients occur frequently fragile fractures, and femoral fractures are the common traumatic injuries in the elderly. Although wires are often used through trials-and-errors for unstable femoral proximal fractures with DHS fixation clinically, there is no efficacy wire fixation technique available due to the lack of biomechanical study. FEM is applied to analyze the stress and strain distribution...
The peripheral quantitative computed tomography (pQCT) is increasingly being used to monitor bone mineral density (BMD) change in both research and clinical practice in order to evaluate the fracture susceptibility in old people or the effect following therapeutic intervention^. . In follow-up studies, the drift area (change area) of total cross-sectional area (CSA) comparing with that of the baseline...
Falls and the resulting hip fractures in the elderly are a major health and economic problem. The goal of this study was to investigate the feasibility of a portable preimpact fall detector in detecting impending falls before the body impacts on the ground. It was hypothesized that a single sensor with the appropriate kinematics measurements and detection algorithms, located near the body center of...
