Which ligament of the hip joint is the strongest and most important restraint against hyperextension of the hip?

• A Ischiofemoral ligament
• B Pubofemoral ligament
• C Ligamentum teres
• D Iliofemoral ligament ✓

Explanation

The iliofemoral ligament, also called the Y shaped ligament of Bigelow, is the strongest ligament of the hip joint. It arises from the anterior inferior iliac spine and blends with the capsule before attaching to the intertrochanteric line. It becomes taut on extension and therefore prevents hyperextension and assists upright standing without muscular effort. The ischiofemoral ligament is the weakest of the three capsular ligaments, and the ligamentum teres carries the foveal artery but contributes little mechanical stability.
