pubofemoral

The pubofemoral ligament is a thickening of the anterior part of the hip joint capsule that strengthens the joint alongside the other capsular ligaments. It originates from the pubic portion of the acetabular rim and the superior pubic ramus, and its fibers run downward and laterally to insert on the femoral neck, blending with the joint capsule and the surrounding ligaments.

Functionally, the pubofemoral ligament limits excessive abduction and extension of the hip and contributes to anterior and medial stability of the joint. It becomes taut during extension and abduction, helping to prevent dislocation during movement and load bearing.

Anatomically, the pubofemoral ligament lies anteriorly and inferiorly in the hip capsule and is typically described as part of the standard trio of hip ligaments, along with the iliofemoral and ischiofemoral ligaments. Its integrity is important for normal hip mechanics, and injury or laxity can contribute to instability or altered range of motion. In clinical practice, damage to the ligament may be considered in the assessment of hip sprains, dislocations, or postoperative hip stabilization.
