Background& Objective: Femoral neck anteversion angle (FNA) and neck-shaft angle (NSA) or inclination angle are important anatomic indicators in clinical orthopedics. Main aim of this study, is to determine correlation between FNA and NSA to prediction one of these parameters from other to designing of hip prostheses .Methods: Each femur was placed with the posterior surface of its condyles and greater trochanter touching a smooth horizontal surface (Kingsley and Olmsted method). For measurement of anteversion angle, Retrocondylar axis andfemoral neck axis were made with digital photography and with Digimizer software. For measurement of inclination angle, femoral neck axis and Diaphyseal axis were made with same manner. Results: 159 dried femora were studied. Average anteversion angle in degree for male was 12.17° (±6.83°) and in female was 15.14° (±9.17°). According to this study, in left male femur, for one degree increase in NSA, FNA grows 0.38°; in right male femur, for one degree increase in NSA, FNA grows 0.74°; in right female femur, for on degree increase in NSA, FNA grows 1.55°.Interpretation& Conclusion:In this research, we found that there is a meaningfulpositive relationship between FNA and NSA, to prediction on of them from the other. This relationship is seen in male femur (right and left) and Female femur (just right). [Ehsangolchini NJIRM 2016; 7(5): 25-32]
