Angle of femoral torsion, femoral neck anteversion (FNA), medial femoral torsionAbstract
Background: The femur is thighbone. The angle of femoral torsion is the angle obtaining between the transverse axes of the neck and head that of the lower end of the bone. In the adult, the angle measures about 12 to 15 degrees, but it is considerably greater in the fetus and at birth averages 40 degrees. In postnatal development a reduction of the FNA angle usually occurs during growth. Aim: to evaluate femoral torsion value on dried femora and to find the difference between Japanese, Caucasian and Indian femoral torsion. Method: The present study was carried out on 200 dry normal adult human femora. The bones studied were free of any pathological condition. The male bones were 117 and 83 were female femora out of 200 dried femora. Out of 111 were left and 89 were right femora. The gender of each specimen was determined by the recognized established practice. The angle of anteversion as measured by placing the femur on the osteometric board, the horizontal surface represents the retrocondylar axis and the plane of reference against which the anteversion is measured with the help of the axis of head and neck of the femur. Results: The average anteversion is 16.1 and 15.65 on the right and left sides respectively in male, 18.17 and 17.95 on the right and left sides respectively in female. Statistical analysis using ‘z’ test revealed significant (p<0.05), greater average anteversion in female bones and right-left variations, being greater on the right side. Conclusion: The objective measurement of this angle is of paramount importance in orthopedic surgery for total replacement to attain a normal activity of the replaced joint.
