By Gregory R. Waryasz, MD

The ischiofemoral ligament of the musculoskeletal system is characterized by its location and being the weakest of the three intrinsic hip ligaments.

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 posteriorly located and triangular shaped.  It connects the ischial part of the acetabular rim with the femoral neck and the base of the greater trochanter.

The ischiofemoral 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 ischiofemoral ligament prevents medial rotation of the hip.  The ligaments of the hip also help to reinforce the hip capsule.

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.
