FEMOKO-TIBIAL ARTICULATION OR STIFLE-JOINT 



■Jio 



The Cotyloid Ligament is u lino of iibro-cartilage attached around 

 the inargiu of the cotyloid cavity. It serves to increase the depth of 

 the cup, and at the same time to give it a yielding margin for the protec- 

 tion of the head of the femur. This Ii2;an)ent bridges over the notch in 

 the inner part of the cup through which the pubio-femoral reaches the 

 head of tlie thigh-bone. 



The Round Ligament {Uga- 



ynentum teres) is a short, strong 

 fibrous cord extending from the 

 bottom of the acetabulum to the 

 inner side of the head of the femur. 



The Pubio-femoral Liga- 

 ment, although short, is longer 

 and thicker than the round liga- 

 ment. It is derived from the ten- 

 dons of the abdominal muscles, 

 which, in front of the pubes, cross 

 from right to left and left to right, 

 and then proceed to the head of 

 the femur to be attached beside 

 the round ligament. 



The hip-joint is capable of the most varied and extensive movements. 

 Net only is it freely flexed and extended, but as constructed it also permits 

 of abduction, adduction, circumduction, and rotation of the femur on the 

 acetabulum.

FEMORO-TIBIAL ARTICULATION OR STIFLE-JOINT 



This is the corresponding joint to the knee of man. It is formed by 

 the union of the femur with the tibia on the one part, and with the patella 

 or knee-cap on the other. The femur articulates with the upper extremity 

 of the tibia by its two condyles, and with the patella by its two ridges 

 or trochlea in front. Between the two condyles and the head of the 

 tibia there are two crescentic pieces of fibro-cartilage (semihtnar cai-tiJages) 

 which serve to mould the rounded condyles of the thigh-bone upon the 

 flatter articular face of the tibia. 



The three bones composing this joint are united by numerous strong 

 ligaments, so disposed as to jiermit the greatest freedom of motion, while 

 at the same time offering adecjuate resistance to the great strain which 

 is thrown upon them. 



The ligaments are divisible into three sets, viz. those which connect
