Materials and Methods: This is a prospective study conducted in a 3-year period. Hip X-Rays of all patients with femoral neck fracture were assessed by the Singh method to confirm osteoporosis. To rull out other illnesses like osteomalacia, measuring serum calcium, phosphorous and alkalin-phosphatase were considered. Information about sex, age, height, weight, previous and present job, smoking history, diet regimen, exercise and duration of daily walking in younghood until now, cause and side of fracture, history of hip fractures in patients and their parents, history of fall in previous months, kifosis, back pain, height loss, decrease of vision and history of diseases and surgeries were collected. Descriptive statistics were presented and the two sexes were compared using c ² and t-test.

Results: 114 patients were diagnosed as osteoporotic related fracture. 54.4% were female and 45.6% were male with the mean age of 72.52 ± 12.34 years. 22% were smokers and 16% used milk in their daily diet. Only 20% had regular exercise in younghood. Falling while walking and from low height (49.1% and 33.3%) were the most prevalent causes of fracture. 14% of males and 18% of females had the history of hip fracture in the other side. 12.9% of females and 5.8% of males had a history of femoral neck fracture in their mothers and 8.1% of females and 17.3% of males had a history of fracture in their fathers. Significant differences were found between both sexes for height and weight (p≤001), exercise (p≤0.004), walking in younghood (p≤0.03) and smoking (p≤0.001).

Conclusion: Due to the high rate of femoral neck fractures and its consequences, it is necessary to carry out some preventive measures. So public education for altering lifestyle, diet regimen and regular exercise is important.
