The hip is supported by three ligaments: the iliofemoral ligament, the ischiofemoral ligament, and the pubofemoral ligament. The iliofemoral ligament is commonly referred to as the Y Ligament of Bigelow and is considered to be the strongest ligament in the body. This ligament prevents excessive extension of the hip joint and also supports upright posture. The ischiofemoral ligament is the weakest of the three, and helps stabilize extension of the hip. The pubofemoral ligament limits excessive hip extension and also prevents excessive abduction of the hip. All three ligaments function to limit excessive medial rotation of the femur.
