The Pubio-femoral Ligament, although short, is longer and thicker than the round ligament. It is derived from the tendons of the abdominal muscles, which, in front of the pubes, cross from right to left and left to right, and then proceed to the head of the femur to be attached beside the round ligament.

The hip-joint is capable of the most varied and extensive movements. Not only is it freely flexed and extended, but as constructed it also permits of abduction, adduction, circumduction, and rotation of the femur on the acetabulum.
