Anteversion of the femoral neck in Indian dry femora.
The purpose of this study was to estimate the average angle of femoral neck anteversion in an Indian population. A total of 300 dry femora were classified by standard anatomical norms into male and female types and left-side and right-side types. They were evaluated by the Kingsley Olmsted and parallelograph methods, and the data were statistically analyzed. The average angles of anteversion obtained were 8.1 degrees and 8.3 degrees by the Kingsley Olmsted and parallelograph methods, respectively. The average female-type bone showed about 3 degrees more anteversion than the male-type bone. The average left-sided bone showed about 1.6 degrees more anteversion than the right-sided bone. A statistically significant difference existed between the sexes and the sides. The Kingsley Olmsted and parallelograph methods were found to be comparable with a correlation coefficient of 0.99. Altogether, 42.33%, 57.66%, and 79.00% of bones had readings of 5 degrees -10 degrees, 0 degrees -10 degrees, and 0 degrees -15 degrees, respectively. Thus, femoral neck anteversion has been found to be less in the Indian population than in Western populations.
