The hip bone is known as the hip bone, which is located in a wide area, mainly below the level of the abdomen and above the inner side of the thigh. There are two hip bones, each consisting of the pubic bone, the sciatic bone and the iliac bone, which are connected to each other by cartilage at an early age, and then the cartilage gradually ossifies to form a whole. The hip bones, in turn, together with the sacrum and coccyx, make up the pelvis of our body. On the left and right sides of the waist, we can feel the iliac wing of the ilium, the anterior superior iliac spine, etc. When sitting down, the buttocks are in contact with the stool, and that part of the bone that can be felt under the skin is the sciatic tuberosity of the sciatic bone, and in the position of 20~25cm directly below our navel, we can feel a bony protrusion of the pubic bone, which is the pubic tuberosity of the pubic bone. Understanding the structure of the hip bone is of some significance in determining the location of the lesion, and when there is discomfort in the hip, it is recommended to consult a doctor in time and follow the doctor’s instructions for treatment.
