Dissection of female pelvis from a lateral approach Exterior of pelvis with femur removed, right lateral view The right thigh has been detached by disarticulating the femur at the hip joint. Muscles of the gluteal region have been cut off in various ways to demonstrate their interrelations. The obturator externus and pectineus muscles have been completely removed. The periosteum has been stripped from the rami of the pubis and ischium. In succeeding views of this sequence the dissection of the specimen is continued into the interior of the pelvis. 1 .
