This study is to investigate the association between fracture probabilities determined by using the fracture risk assessment tool (FRAX) and the microstructure and mechanical properties of femoral bone trabecula in osteoporosis (OP) and osteoarthritis (OA) patients with hip replacements. By using FRAX, we evaluated fracture risks of the 102 patients with(More)
A new design of signal to noise ratio (SNR) measurement for single shot laser pulses, based on a stepped grating and an optical Kerr gate (OKG), is presented. A single shot laser pulse was simultaneously divided into multi-pulses in both time and space. Intensity-space distribution of laser multi-pulses, which was recorded with a CCD detector, was(More)
In this study, we report a case of avascular necrosis of the femoral head (ANFH) caused by the bilateral intravenous injection of heroin into the femoral vein. The patient had not used steroids, did not smoke and did not drink excessively. The patient did not present with any systemic diseases that may cause ANFH. ANFH often causes changes to the bone mass(More)
