Sex differences in human physiology pelvis is, in general, different between the human female and male skeleton. It differs both in overall shape and structure. The female pelvis, adapted for gestation and childbirth, is less high, but proportionately wider and more circular than in the male; its sacrum—the triangular bone at the upper posterior of the pelvic cavity, serving as base of the spine—is also wider. The female pelvis is tilted anteriorly, often resulting in the more sway-backed appearance. In the female, the acetabula, the concave surfaces to which the balls of the femurs attach via ligaments, are located farther apart, which increases the distance
Artificial bone fractured bone. However, if damage to bone is caused by a disease or severe injury, it becomes difficult for the body to repair itself. When the human body is unable to regenerate the lost bone tissue, surgeons come in and replace the missing bone using autografts, allografts, and synthetic grafts (artificial bone). When compare artificial bone to autograft and allograft, it is less invasive and more biocompatible since it avoids the risk of unknown viral infections. When designing implanted biomaterials, key criteria are biocompatibility, osteoconductivity, high porosity and biomechanics compatibility. Artificial bone was initially made of materials like metals and
