Introduction[edit | edit source]
The hip joint is composed of five ligaments, where four are extracapsular and one intracapsular. The extracapsular ligaments are the iliofemoral, the ischiofemoral, the pubofemoral and the annular ligament (or zona orbicularis), the intrcapsular one is the ligament of the head of the femur. The iliofemoral ligament is also called Y ligament for is triangular shape or ligament of Bigelow, the name of the American surgeon who, among other things, described this ligament in details and invented the Bigelow maneuver for hip dislocation. [1]
Anatomy[edit | edit source]
The iliofemoral ligament arises from the anterior inferior iliac spine (AIIS) and from the rim of the acetabulum, and it runs obliquely and attaches to the intertrochanteric line of the femur. It is composed of two bands, a medial band that is vertically oriented and runs almost parallel to the femoral shaft, and a lateral band that has fibers obliquely directed and runs parallel to the axis of the femoral neck. These two bands create the Y-shape.
Function[edit | edit source]
This is the strongest ligament in the body. The iliofemoral ligament limits extension and external rotation of the hip and assists in maintenance of a static erect posture with minimal muscular activity
