the iliofemoral artery
The three extracapsular ligaments of the hip joint the iliofemoral, ischiofemoral, and pubofemoral ligaments form a twisting mechanism encircling the neck of the femur.
The iliofemoral ligament prevents excessive adduction and internal rotation of the hip.
Constant hip rotation places increased stress on the capsular tissue and damage to the iliofemoral ligament.
The extracapsular ligaments are the iliofemoral, ischiofemoral, and pubofemoral ligaments attached to the bones of the pelvis (the ilium, ischium, and pubis respectively).
The pubofemoral ligament is located anteriorly just underneath the iliofemoral ligament and serves primarily to resist abduction, extension, and some external rotation.
The iliofemoral ligament -- the largest ligament of the human body -- attaches above the line which also strengthen the capsule of the hip joint.
Front splits require hyper-extension of the iliofemoral ligament, otherwise the majority of the range of motion must come from the front hip joint.
Anteriorly they blend with the deep surface of the iliofemoral ligament, and gain an attachment to the anterior inferior iliac spine.
