ligamentum teres femoris
anatomy
Quick Summary
The ligamentum teres femoris is a ligament that helps hold the head of the femur (the upper bone of the leg) in place within the hip socket. This forms a crucial part of the ball-and-socket joint of the hip. In humans, this ligament contributes to the stability of the hip joint. Some animals, like the orangutan, lack this ligament, which allows for greater rotation of the leg but reduces stability. The femur itself is the longest and strongest bone in the human body, capable of withstanding significant force.1
