recti femoris, and the bursa iliaca subtendinea. Reflect the M. 

 tensor fasciae latae. Clean the outer surface of the hip-joint. 



The joint is an enarthrosis. What is meant by this? What 

 bony surfaces are concerned! 



Study the following ligaments (Figs. 62 and 63) : 



(a) Joint-capsule (capsula articularis). 



(b) Strengthening ligaments. 



(ba) Iliofemoral ligament (ligamentum iliofemorale) (0. T. Y- 



shaped ligament of Bigelow ) . 



(baa) Superior fasciculus to tubercle in front of great 

 trochanter (Lig. iliofemorale superius).

Frontal section of the articulatio coxae, passing through the fovea capitis femoris (From 

 Poirier et Charpy, Traite d'Anat. hum., Paris, 1899, 2 ed., t. i. p. 7-M, 1' ' 



(bab) Anterior or inferior fasciculus to tubercle in front 

 of small trochanter (/.///. iliofemorale ///// rin). 



This is perhaps the strongest ligament in tho 

 body. It will resist a strain of from two hundred 

 and fifty to seven hundred and fifty pounds. 

 (bb) Ischiocapsular ligament (ligamentum ischiocapsular^ 



ischiocapsular band). 

 (be) Pubocapsular ligament (ligamentum j.ul.n.apsulan 



pubocapsular band or pubofemoral l.uamrnt ) 

 (bd) Orbicular zone (zona orhn-nlans) ,O. T. xonular 1 

 ring ligament).
