Ischiofemoral ligament

Ischiofemoral Ligament

The Ischiofemoral ligament is a band of strong fibrous tissue that connects the ischium part of the hip bone to the femur, the thigh bone. It is one of the three main ligaments that provide stability to the hip joint.

Anatomy

The ischiofemoral ligament originates from the ischial part of the acetabulum, the socket of the hip joint. It extends laterally and superiorly to attach to the femur, just behind the greater trochanter. This ligament is the posterior counterpart to the iliofemoral ligament and pubofemoral ligament, which are located anteriorly and inferiorly, respectively.

Function

The primary function of the ischiofemoral ligament is to stabilize the hip joint. It prevents excessive internal rotation and adduction of the hip. In addition, it helps to limit the range of motion of the hip joint, preventing hyperextension.

Clinical Significance

Damage to the ischiofemoral ligament can lead to instability of the hip joint, which can result in pain and limited mobility. This can occur due to trauma, overuse, or degenerative conditions such as osteoarthritis. Treatment typically involves physical therapy, pain management, and in severe cases, surgery.

Etymology

The term "ischiofemoral" is derived from the Latin words "ischium" meaning hip, and "femur" meaning thigh. Thus, the term refers to the ligament connecting the hip and the thigh.
