COXAL ARTICULATION OR HIP-JOINT 



The Hiofemoral Ligament (lig amentum iliofemorale; Y-ligament; ligament o/ 

 Bigelow) (Fig. 339). The iliofemoral ligament is a band of great strength which 

 lies in front of the joint; it is intimately connected with the capsule, and serves 

 to strengthen it in this situation. It is attached, above, to the lower part of the 

 anterior inferior iliac spine; below, it divides into two bands, one of which passes 

 downward and is fixed to the lower part of the intertrochanteric line; the other 

 is directed dow r nward and lateralward and is attached to the upper part of the 

 same line. Between the two bands is a thinner part of the capsule. In some 

 cases there is no division, and the ligament spreads out into a flat triangular band 

 which is attached to the whole length of the intertrochanteric line. This ligament 

 is frequently called the Y-shaped ligament of Bigelow; and its upper band is some- 

 times named the iliotrochanteric ligament.

The Pubocapsular Ligament (ligamentum pubocapsulare; pubofemoral ligament}, 

 This ligament is attached, above, to the obturator crest and the superior ramus 

 of the pubis; below, it blends with the capsule and with the deep surface of the 

 vertical band of the iliofemoral ligament. 



The Ischiocapsular Ligament (ligamentum ischiocapsulare; ischiocapsular band; 

 ligament of Bertiii).- The ischiocapsular ligament consists of a triangular band of 

 strong fibers, which spring from the ischium below and behind the acetabulum, 

 and blend with the circular fibers of the capsule (Fig. 340").
