The pelvis is the bony part of the body formed by the junction of three bones, two similar bones called the sacrum and one bone called the sacrum. A cavity called the acetabular cavity is formed from the placement of the three sacrum and sacrum bones next to each other. Anatomy of the pelvis or pelvis is the middle part of the human body, located between the abdomen (spine) and the thighs. The human pelvis consists of the bony part, the pelvic cavity, the pelvic floor and the perineum. In addition, the digestive system, reproductive organs, muscles and many veins are located inside the pelvis. Apart from bearing the weight of the body, the pelvis can transfer the weight of the upper part of the body to the lower limb and act as a connection point to connect the muscles of the lower limb and the trunk. When sitting, all the weight of the body is directly transferred to the surface through the pelvis. In addition, the pelvis protects the pelvic and abdominal viscera. The hip joint in the pelvis is the most important part in movement.
