iliofemoral ligament

The iliofemoral ligament prevents excessive adduction and internal rotation of the hip.

Maximal extension is inhibited by the iliofemoral ligament.

Of these, the Y-shaped and twisted iliofemoral ligament is the strongest ligament in the human body.

Anteriorly they blend with the deep surface of the iliofemoral ligament, and gain an attachment to the anterior inferior iliac spine.

The iliofemoral ligament - the largest ligament of the human body - attaches above the line which also strengthen the capsule of the hip joint.

The iliofemoral ligament inhibits lateral rotation and extension, this is why the hip can rotate laterally to a greater degree when it is flexed.

Front splits require hyper-extension of the iliofemoral ligament, otherwise the majority of the range of motion must come from the front hip joint.

The iliofemoral ligament is a ligament of the hip joint which extends from the ilium to the femur in front of the joint.

The pubofemoral ligament is located anteriorly just underneath the iliofemoral ligament and serves primarily to resist abduction, extension, and some external rotation.

They include the iliofemoral ligament, the teres ligament, the pubofemoral ligament, the ischiofemoral ligament, and the zona orbicularis ligament.

The columns of Bertin are named after him, as are "Bertin's ossicles" (sphenoidal conchae) and "Bertin's ligament" (iliofemoral ligament).

The longitudinal fibers are greatest in amount at the upper and front part of the capsule, where they are reinforced by distinct bands, or accessory ligaments, of which the most important is the iliofemoral ligament.

Arising from the anterior inferior iliac spine and the rim of the acetabulum, the iliofemoral ligament spreads obliquely downwards and lateralwards to the intertrochanteric line on the anterior side of the femoral head.

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.

Below the notch is the anterior inferior iliac spine, which ends in the upper lip of the acetabulum; it gives attachment to the straight tendon of the Rectus femoris and to the iliofemoral ligament of the hip-joint.

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.

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.

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.
