Explanation
The bones of the pelvis and lower limbs serve structural and weight-bearing roles in the body. Understanding their features and landmarks is essential for identifying anatomical functions and clinical relevance.
The hip bone, also known as the coxal bone, is formed by the fusion of the ilium, ischium, and pubis. The ischial tuberosity supports the body’s weight when sitting. At the front, the pubic symphysis joins the two hip bones. The iliac crest is the upper curved edge of the ilium and forms the top of the hip. The acetabulum is a deep socket that receives the femur head, forming the hip joint. This joint connects to the axial skeleton through the sacroiliac joint.
The femur is the longest and strongest bone, crucial for movement and support. The fibula is thinner and lies on the outer side of the leg. The greater sciatic notch allows the passage of the sciatic nerve, while the lesser sciatic notch is located below it.
At the knee, the patella or kneecap protects the joint, and the femur provides an attachment for ligaments. The tibia is the shinbone and bears most of the body weight, ending in the medial malleolus, while the fibula ends in the lateral malleolus.
In the foot, the calcaneus is the heel bone, and the tarsals form the ankle. The metatarsals make up the instep. The obturator foramen, formed by the pubis and ischium, allows the passage of blood vessels and nerves.
These structures all contribute to posture, balance, and locomotion
