Abstract

Fracture of femur is considered as one of the most significant causes of disability and death, especially among the elderly people. Therefore, there is a global effort towards non-invasive assessment of the femoral fractures. The purpose of the present research was to compare the femoral neck fracture pattern in both normal and abnormal angles in active and non - active postmenopausal women.
 In this way, 20 postmenopausal women (54.2±2.5 years) were selected as active and non-active groups among all of the patients that registered in the CT scan department of the city hospital during the past three years. In this way, some parameters such as: the geometric data, density of the bone and also the type of bone based on their angles including Coxavara and Coxavalga of the hip joint were calculated by CT-Scan device.
The experimental and computational analysis of fracture patterns were carried out using Finite element method, whereas the model was simulated by 3D Max software. For statistical analysis after using kolmogorov smirnov tnormalization test, two-way ANOVA and Pearson correlation tests were used. Moreover, the data were analyzed with Abacus and SPSS 19 software and the level of significant set as p≤0.05. 
The results showed that there is no significant difference between the femoral neck fracture pattern in both normal and abnormal angles between two groups (p≥0.05). Moreover, the geometry and density of the femoral neck did not indicate any significant effect on fracture pattern of the hip joint angles. Therefore, it seems that the geometric data could not consider as the predictor indices during fracture pattern of the femoral neck angle in postmenopausal women.
