The head of the femur articulates with the acetabuhim. The obturater foramen, the anotomical neck of the femur, its surgicalneck, its greater and lesser trochanters, the intertrochanteric line, are allplainly visible. At the upper extremity of the intertrochanteric line, at a point wherethe shadow of the neck of the femur meets that of the shaft, a V-shapeddark line indicates the position of the digtal fossa. Above the outermargin of the acetabulum is the groove for the tendon of the; rectusmuscle. Note particularly the angle formed by the head and the neck of thefemur with the shaft of that bone.
