Lower Limb Bones

Lower limb bones

The human lower limb is probably one of the greatest features we’ve got from evolution, as it provides us with bipedal mobility and activities such as running, jumping and dancing. From superior to inferior, the lower limb consists of the thigh, leg and foot.

The core of the thigh is composed of the strongest bone of the human body, the femur. Proximally, the femur articulates with the hip bone, composing the hip joint, which attaches the lower limb to the trunk. Distally, the femur participates in the complex knee joint, together with the patella and tibia. The knee joint, thus, is a connection between the thigh and leg.

The leg consists of the tibia and fibula. Distally, both of them participate in the ankle joint via which the leg connects with the foot. The foot bone that takes part in the ankle joint is called the talus.

Similar to the hand, the foot also consists of three groups of bones:

  • 7 tarsal bones, that compose the heel and root of the foot
  • 5 metatarsal bones, that comprise the sole and dorsum of the foot, as well as the roots of the toes
  • 3 sets of phalanges (proximal, middle, distal), which build the skeleton of the toes. Note that the big toe (hallux) is devoid of middle phalanx, consisting just of the proximal and distal phalanges.
