Background: Diversity in Proximal Femur Geometric Parameters (PFGPs) will be led to frequency changes in hip fractures. The purpose of the present study is to investigate of the relation between Bone Mineral Density (BMD) in proximal femur with Neck Shaft Angle (NSA) in both of osteoporotic and normal groups among old postmenopausal women in eastern part of Mazandaran province as a appropriate indicator to predict hip fractures occurance.

Materials and Methods: Among 5103 postmenopausal women reffered to bone densitometry center, for 221 postmenopausal women who had inclusion criteria to this study, simultaneously by using densitometry system and completing a standard questionnaire, history of disease and demographic information including body mass index (BMI) were recorded for each patient. Obtained information from densitometers was analyzed by the statistical software SPSS version 16 and Pearson correlation coefficient test was used.

Results: Geometric parameters of 221 post-menopausal women aged 50 to 60 were analyzed. The mean of neck shaft angle (NSA) were recorded for osteoporotic group 121.55 and for control group 121.44. Pearson correlation coefficient t-test results showed a negative significant correlation between mineral density in the femoral neck in osteoporotic group and NSA (P<0.05). Considering the effect of weight and BMI in strength and bone density in the femoral neck, the mean of BMI and weight in osteoporotic group was lower compared to control group.

Conclusion: according to the findings of this study, NSA is effective in predicting of the proximal femur BMD in osteoporotic group.
