The hip region is located lateral and anterior to the gluteal region (i.e., the buttock), inferior to the iliac crest, and overlying the greater trochanter of the femur, or thigh bone. In adults, three of the bones of the pelvis have fused into the hip bone or acetabulum which forms part of the hip region.
The well-fitting surfaces of the femoral head and acetabulum, which face each other, are lined with a layer of slippery tissue called articular cartilage, which is lubricated by a thin film of synovial fluid. Friction inside a normal hip is less than one-tenth that of ice gliding on ice.ontributing a little more than two-fifths of the structure is the ischium, which provides lower and side boundaries to the acetabulum. The ilium forms the upper boundary, providing a little less than two-fifths of the structure of the acetabulum. The rest is formed by the pubis, near the midline.
