Abstract:
A new instrument was devised to determine the angle between the long axis of the neck and the bicondylar plane of the femur.The superior border of the neck was first determined by a line connecting the two superior ends of the junctions between “head and neck,”and “neck and great trochanter” respectively;the inferior border being determined in similar way.(2)The angle between the superior border of the neck and the bicondylar plane and (3) the angle of the inferior border with the same plane were then measured.(4)The average of the two angles was taken as the angle of torsion of the neck. Three hundred femurs of both sexes were measured.It was found that the angle of torsion of the neck in the adult male is 7.88?,and that in the females is 9.37?.The average value is 8.66?. It was discussed how the angle of torsion in the neck is formed,perhaps it results from the pulling effect of the muscles.
