Iliofemoral Ligament, Lateral View

Description

Seen from the lateral aspect, the hip joint is framed by the acetabulum of the os coxae and the proximal femur, with the femoral head seated in the socket and the femoral neck projecting anteroinferiorly toward the shaft. Spanning the anterior capsule, the iliofemoral ligament runs from the anterior inferior iliac spine and adjacent acetabular rim to the intertrochanteric line, fanning into a broad, Y-shaped band across the anterolateral joint. Superiorly, the lower lumbar vertebrae and intervertebral discs establish bony context, while the sacroiliac joint sits posterior to the acetabulum as a stable reference point. Clear landmarks. Clinically, this lateral perspective makes it easier to teach how the iliofemoral ligament checks hip extension and external rotation in standing, explaining why the joint can remain stable with minimal muscular activity. Surgeons approach this region during anterior and anterolateral hip arthroplasty, capsulotomy, and arthroscopy, where preserving or repairing the iliofemoral ligament relates to postoperative stability and anterior dislocation risk. Traumatic anterior hip dislocation and capsular laxity from hyperextension injuries can be discussed directly from the ligament’s femoral attachment along the intertrochanteric line. Use this asset for gross anatomy lab guides, orthopedic lecture slides on capsuloligamentous restraints of the hip, and exam figures contrasting iliofemoral with pubofemoral and ischiofemoral ligament orientation. It also fits well in patient-facing surgical education materials explaining why certain hip precautions limit extension and external rotation after anterior approaches.
