249. Right hip joint, articulatio coxae, 



from behind. 

 (The joint capsule, except for the strengthening ligaments, has been removed.) 



Articulatio coxae (continued) (see also Figs. 248, 250 252). It possesses, as a streng- 

 thening ligament of the posterior wall of the capsule, the ligamentum ischiocapsulare. This 

 broad, thick ligament arises externally along the margin of the acetabulurn in the whole extent 

 of the corpus ossis ischii; its fibres converge somewhat, run obliquely upward and lateralward 

 and become attached for the most part to the zona orbicularis ; part of them reach even to the 

 anterior margin of the trochanter major. 



Between the ligamenta iliofemorale, pubocapsulare and ischiocapsulare, the capsule is 

 essentially thinner in three places; these places correspond to the points where the 

 forming the acetabulum fuse with one another.
