The iliofemoral ligament of the musculoskeletal system is characterized by its location and being the strongest hip ligament and ligament in the body.
It is part of the hip joint. It consists of fibrous dense regular connective tissue of collagen fibers.
Its unique structural feature is that it is Y-shaped. It attaches the anterior inferior iliac spine (AIIS) and acetabular rim to the intertrochanteric line. It is located in the anterior and superior part of the hip joint.
The iliofemoral ligament as well as all other bones, muscles, and ligaments of the body are derived of mesodermal origin in the embryo.
The function of the iliofemoral ligament is to prevent hyperextension of the hip joint due to its twisted and tense structure.. The ligaments of the hip also help to reinforce the hip capsule. The tensile strength of the ligament is said to exceed 350 Newtons of force.
Common diseases include ligament tears.
Commonly used diagnostic procedures include clinical history, physical exam, and MRI.
It is usually treated with physical therapy and NSAIDs. Surgery can be performed either with a large open incision or performed with arthroscopy.
