Ischiofemoral Ligament

Introduction[edit | edit source]

The hip joint is reinforced by three primary fibrous capsular ligaments, including the ischiofemoral ligament, which plays a crucial role in stabilizing the joint. [1]This ligament, along with the iliofemoral and pubofemoral ligaments, contributes to the overall stability and function of the hip joint.

  • The ischiofemoral ligament originates from the ischium at a point below and behind the acetabulum and attaches to the intertrochanteric line of the femur.
  • It attaches to the posterior surface of the acetabular rim and acetabular labrum, extending around the circumference of the joint to insert on the anterior aspect of the femur.

Here is a video to explain the major ligaments of hip joint clearly.


Function[edit | edit source]

The ischiofemoral ligament restricts internal rotation of the hip joint, particularly in relation to hip flexion angles. Studies have shown that this ligament, along with the iliofemoral ligament, plays a significant role in preventing excessive internal hip rotation and maintaining joint stability.[3]

Clinical Relevance[edit | edit source]

Injuries to the ischiofemoral ligament can occur in dislocations, leading to lesions of the foveal artery and potentially resulting in osteonecrosis of the femoral head. The ligament is also associated with conditions like hip joint effusion, fractures, dislocations, ischiofemoral impingement syndrome and congenital dislocation of the hip, highlighting its clinical relevance in hip pathologies.[4]
