Ischial tuberosity to intertrochanteric crest.
The ischial tuberosity (or tuberosity of the ischium, tuber ischiadicum), also known informally as the sitz bone, or as a pair the sitting bones) is a large swelling posteriorly on the superior ramus of the ischium. It marks the lateral boundary of the pelvic outlet. Wiki
The intertrochanteric crest is a bony ridge located on the posterior side of the head of the femur, stretching obliquely downward and medially from the summit of the greater trochanter to the lesser trochanter. Wiki
Laterally rotates at hip joint.
Quadratus Femoris acts to cause lateral rotation and adduction of thigh.
Innervation – Nerve control
Nerve to quadratus femoris .
The nerve to quadratus femoris is a nerve that provides innervation to the quadratus femoris and gemellus inferior muscles.
Inferior gluteal artery.
The inferior gluteal artery (sciatic artery), the smaller of the two terminal branches of the anterior trunk of the internal iliac artery, is distributed chiefly to the buttock and back of the thigh. It passes down on the sacral plexus of nerves and the piriformis muscle, behind the internal pudendal artery, to the lower part of the greater sciatic foramen, through which it escapes from the pelvis between the piriformis and coccygeus.

Gluteus minimus, Tensor fasciae latae.
The gluteus minimus, located beneath the gluteus medius, is the smallest of the three gluteal muscles. The tensor fasciae latae muscle is in the thigh, and it assists in keeping the balance of the pelvis while standing, walking, or running.
