Iliofemoral Ligament

The Iliofemoral Ligament is a crucial component of the human anatomy, specifically within the hip joint. It is also known as the Y-Ligament or the Ligament of Bigelow, and is one of the strongest ligaments in the human body.

Etymology[edit | edit source]

The term "Iliofemoral" is derived from the Latin words "ilium" and "femur", which refer to the pelvis and the thigh bone respectively. The ligament's alternate name, "Ligament of Bigelow", is named after the American surgeon Henry Jacob Bigelow, who first described it in detail.

Anatomy[edit | edit source]

The Iliofemoral Ligament is located in the pelvis, connecting the ilium (the largest bone of the pelvis) to the femur (the thigh bone). It is Y-shaped, hence its nickname the "Y-Ligament". The ligament is known for its strength, which is necessary to maintain the stability of the hip joint.

Function[edit | edit source]

The primary function of the Iliofemoral Ligament is to restrict hip extension and prevent hyperextension, thus providing stability to the hip joint. It also assists in maintaining the upright posture without the need for muscular activity.

Clinical Significance[edit | edit source]

Injuries to the Iliofemoral Ligament can cause significant pain and mobility issues. Such injuries are often the result of trauma, such as a car accident or a sports injury. Treatment typically involves rest, physical therapy, and in severe cases, surgery.
