The iliofemoral ligament is a ligament of the hip joint which extends from the ilium to the femur in front of the joint.
The extracapsular ligaments are the iliofemoral, ischiofemoral, and pubofemoral ligaments attached to the bones of the pelvis (the ilium, ischium, and pubis respectively).

Anterior inferior iliac spine

anterior inferior spine
Arising from the anterior inferior iliac spine and the rim of the acetabulum, the iliofemoral ligament spreads obliquely downwards and laterally to the intertrochanteric line on the anterior side of the femoral head.
The upper portion of the spine gives origin to the straight head of the rectus femoris muscle, while a teardrop-shaped lower portion gives origin to the iliofemoral ligament of the hip joint and borders the rim of the acetabulum.

the ligament of Bigelow, the ligament of Bertin and any combinations of these names.
Bigelow described the structure and function of the Y-ligament of the hip joint in great detail, and it still carries his name.

Intertrochanteric line

trochanteric
Arising from the anterior inferior iliac spine and the rim of the acetabulum, the iliofemoral ligament spreads obliquely downwards and laterally to the intertrochanteric line on the anterior side of the femoral head.
The iliofemoral ligament — the largest ligament of the human body — attaches above the line which also strengthens the capsule of the hip joint.

Pubofemoral ligament

pubocapsularpubofemoral
With a tensile strength exceeding 350 kg (772 lbs), the iliofemoral ligament is not only stronger than the two other ligaments of the hip joint, the ischiofemoral and the pubofemoral, but also the strongest ligament in the human body and as such is an important constraint to the hip joint.
This ligament is attached, above, to the obturator crest and the superior ramus of the pubis; below, it blends with the capsule and with the deep surface of the vertical band of the iliofemoral ligament.

Pelvis

pelvicpelvic girdlehip
In a standing posture, when the pelvis is tilted posteriorly, the ligament is twisted and tense, which prevents the trunk from falling backwards and the posture is maintained without the need for muscular activity.
The three extracapsular ligaments of the hip joint—the iliofemoral, ischiofemoral, and pubofemoral ligaments—form a twisting mechanism encircling the neck of the femur.

Split (gymnastics)

As does the front split where the rear leg is hyper-extended at the hip.

Turnout (ballet)

turnoutturned outturn-in
Turnout used in the classical ballet style requires a great deal of flexibility in this ligament.
The degree of turnout attainable is determined by the shape of the femoral neck and the angle at which the femoral head is inserted into the hip socket, the orientation of the hip socket, the elasticity of the iliofemoral ligament, and the flexibility of the hip and thigh muscles.
