Head
The proximal femur is bent (L-shaped) so that the long axis of the head and neckproject superomedially at an angle to that of the obliquely oriented shaft This obtuseangle of inclination in the adult is 115 to 140 degrees, averaging 126 degrees. Theangle is less in females because of the increased width between the acetabula and the greater obliquity of the shaft. The angle of inclination allows greater mobility of
the femur at the hip joint because it places the head and neck more perpendicular to the acetabulum.
When the femur is viewed superiorly, so that the proximal end is superimposed overthe distal end, it can be seen that the axis of the head and neck of the femur and thetransverse axis of the femoral condyles intersect at the long axis of the shaft of thefemur forming the torsion angle, or angle of declination. The mean torsion angleis 7 degrees in males and 12 degrees in females. The torsion angle, combined withthe angle of inclination, allows rotatory movements of the femoral head within theobliquely placed acetabulum to convert into flexion and extension, abduction and
adduction, and rotational movements of the thigh.
