Definition of Leg Bones

The lower limb, called popularly leg, it consists of a total of 31 bones. These are distributed to form the hip, thigh, knee, leg, and foot.

Hipbones

The hip is the structure that joins the lower limb to the trunk. It consists of one bone, the innominate bone.

Coxal bone. This bone is located at the level of the pelvis and shapes the hip. Internally, it joins the sacrum through the joint sacroiliac and its external part joins the femur forming the hip joint, also known as the hip joint. This bone emits an extension in its anterior part that joins the analog of the contralateral hip bone to form the pubis.

Thigh bones

The thigh is the area of ​​the lower limb located between the hip and the knee. It consists of one bone, the femur.

Femur. It is the longest bone in the body. Its upper end has a rounded shape and is known as the head of the femur, it joins the iliac bone to form the hip joint. The head of the femur is a point vulnerable in the old man, since it is a frequent seat of fractures due to osteoporosis.

Knee bones

The knee consists of its own bone which is the patella.

Ball joint. It is a small, flattened, triangular bone with a lower vertex. The patella is in front of the lower end of the femur, however it is not directly attached to it, so it is a bone of the sesamoid type. The patella is contained within the tendon of the muscle quadriceps, which is the muscle located on the front of the thigh.

Leg bones

The leg is made up of two bones: the tibia and the fibula.

Tibia. It is the main bone of the leg, it is located in its anterior part. Its upper end is wide with a surface flattened call plateau tibialis through which it articulates with the femur and fibula, in its lower part it articulates with the talus, forming the ankle joint. The prominence located on the inner part of the ankle, called the medial malleolus, is the prominence of the lower part of the tibia.

Fibula. It is a thin bone located outside the tibia. The fibula articulates with the tibia in its upper part and with the talus in the lower part, at that level the fibula forms the prominence located on the outer part of the ankle known as the malleolus external.

Foot bones

The foot is a complex structure that consists of 26 bones distributed as follows:

Part later: Astragalus, calcaneus, scaphoid, cuneiform (3) and cuboid bones.

Front part: Metatarsals (5) and phalanges (14).
