The lower limb accounts for 10" of the body weight. The delicate pirouette of the ballet dancer and the relentless plod of the marathon runner are different examples of lower limb movement and control of the centre of body mass. The two hip bones are firmly united anteriorly, in the midline by the pubic symphysis, and posteriorly each articulates with the sacrum at the sacroiliac joints, so forming the bony pelvis. Muscles passing anterior to the hip are the flexors of the hip joint and are closely associated with the femoral vessels and nerve. The femoral pulse can be felt at a point midway between the anterior superior iliac spine and the pubic tubercle. A loop of intestine may protrude through the ring with a peritoneal covering into the canal, so forming a femoral hernia. Inguinal nodes may become involved as a result of disease in the perineum and gluteal region and from the lower limb and lower abdominal wall.
