چکیده

background: bisphosphonates (bps) are used extensively for managing the osteoporosis. there are some controversies on atypical fractures of femur that associated with increase in cortical thickness (ct) and bps' use. in this study, the effects of alendronate consumption were studied on femoral ct as a predictor for atypical fracture.   methods: forty nine post-menopausal women aged 50-70 years with osteopenia-osteoporosis who were treated with alendronate 70 mg/week for at least one year were compared to 49 controls for ct in subtrochanteric region of femur by hip dual-energy x-ray absorptiometry (dxa) scans and hip x-ray. ct and its ratio were measured at 3.5 and 4.0 cm below the tip of the greater trochanter (gt) and 0.5 cm below lesser trochanter (lt) in dxa and at 9.5 and 10.5 cm of gt and 1 cm of lt in x-ray.   results: in this study, 98 women participated whose mean age and age at menopause were 60 (17±5.6) and 49 (40±2.7) years, respectively. duration of bp consumption in alendronate group was 1.76±1.38 (1-10) years.  no difference was seen in the mean of ct and its ratio between the alendronate and control groups in bmd scan or x-ray. the best correlation between two imaging modalities was in cortical ratio in 3.5 cm of gt in bmd scan and 9.5 cm of gt in x-ray.   conclusion: alendronate treatment did not appear to increase femoral ct throughout the detection limits of bmd scan or x-ray.

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

The Effect of Long- Term Alendronate Treatment on the Cortical Thickness Ratio of the Proximal Femur

INTRODUCTION: Alendronate (Aln) is a bisphosphonate agent that has been widely used for the treatment of osteoporosis. Recently, several studies have suggested an association between long-term use of Aln and the occurrence of low-energy subtrochanteric/femoral shaft (ST/FS) fractures. Previous studies described characteristic imaging features of this atypical fracture including transverse orien...
