Study of Femoral Neck Anteversion and its Correlations in Bengali Population
Journal Title: International Journal of Anatomy Radiology and Surgery - Year 2016, Vol 5, Issue 1
Abstract
Introduction: Anteversion is defined as the angle by which the femoral neck deviates forward from the axis of the femoral condyles. The angle of anteversion of the femoral neck varies widely. So, it is important to know the angle of anteversion in a particular population. The accurate estimation of femoral neck anteversion in living subjects has always been difficult, with many shortcomings and lack of reproducibility. Aim: To estimate the average angle of femoral neck anteversion in Bengali population and to find its correlations with gender, side and stature. Materials and Methods: Unpaired 100 dry femurs, 54 of male (33 right and 21 left) and 46 of female (17 right and 29 left), devoid of any gross pathology were used to measure the femoral anteversion angle by parallelogram method. Maximum femoral length was measured by using osteometric board and the data were statistically analyzed. Results: Mean angle of anteversion was 20.05° irrespective of sex and side. In case of male mean value for right side was 18.3° and for left 21.61°. Mean values in female were 19.4° for right side and 21.67° for left side. Though in both males and females the mean values were higher in left sided bones; statistically significant difference was found in case of males only (p < 0.05). However, no statistically significant difference (p > 0.05) was found for the angle of anteversion between the male and female bones in the present study. A statistically significant correlation was found between angle of anteversion and maximum femoral length in both sex and sides with a p-value of < 0.01. Conclusion: The data established in this study will be useful for various orthopaedic procedures. Operative principles of hip prosthesis that capitalize on an impingement-free range of motion, achieving stability and preventing wear embrace an optimal femoral anteversion. This study will also be helpful in the fields of paleodemographic or other population studies and forensic anthropology.
