Femoral Neck Anteversion: Gender Wise Variation in Our Society

Aim: To determine gender wise variation in femoral neck ante-version by anatomic method. Methods: This Descriptive Cross Sectional study was conducted in the Anatomy Departments of three medical institutions at Peshawar, namely, 1) Khyber Medical College, Peshawar. 2) Gandahara Medical College, Peshawar 3) Khyber Girls Medical College, Peshawar from 13 th August 2010 to 12th February 2011. Dry femora of 211 were studied including 189 male and 20 female type and 103 right and 108 left side bones. The angle of femoral neck ante version was determined by the Kingsley and Olmsted method by measuring the angle between the long axis of the neck of femur and the transverse retrocondylar line (in coronal plane) taken as the plane of the axis of shaft of femur. Results: The overall mean angle calculated was 8.1±9.7, with a range of 60.5. Female type bones showed lower mean 6.6±12.2 and narrower range (46) as opposed to male bones (8.3±9.4 and range of 60.5 respectively. Conclusion: There was a gender variation for the femoral neck ante version values in our society. The overall mean of femoral ante version determined is very different from Western, African, and most of the Asian populations and is very close to the Indian society.
