248. Right hip joint, articulatio coxae, 



from in front. 



In the formation of the articulatio coxae (hip joint) (see also Figs. 249 252) the 

 caput femoris moves upon the fades lunata of the acetahulum. The latter is enlarged by 

 means of a high three-cornered connective-tissue ring, labrum f/lenoidale (0. T. cotyloid liga- 

 ment) (see Figs. 250 and 252) which sits with its hroad base upon the border of the aceta- 

 bulum and bridges over the incisura acetabuli as the Ligamentum transversum acetabuli; this 

 has also a broad attachment to the margins of the incisura acetabuli and is connected with 

 the fibres of the membrana obturatoria (see Fig. 246). 



The capsula articularis (see Fig. 252) is strengthened on the anterior surface by the 

 strong triangular ligamentum iliofemorale. It arises below and near the spina iliaca anterior 

 inferior, broadens gradually and is fastened to the linea intertrochanterica in its whole length. 

 The ligamentum pubocapsulare (0. T. pubofemoral ligament) lies on the medial, inferior side 

 of the joint, comes from the corpus and ramus superior ossis pubis and runs partly to the 

 upper margin of the trochanter minor, partly to the capsule in the same region.
