196 ANATOMY IN A NUTSHELL. 



at the lower and hack part of the capsular ligament, (b) The pubofemoral 

 ligament is an accessory ligament and passes from the ilio-pectineal eminence 

 to the rough tubercle in fronl of the lesser trochanter. 



:; The ligamentum teres passes from the margins of the notch at the 

 bottom of the acetabulum to a depression on the head of the femur. It is 

 covered by a n flection of synovial membrane and consists of connective tissue 

 and vessels. 



1 1 The cotyloid ligament surrounds the brim of the acetabulum, making 

 this cavity deeper. It is broad at its point of attachment and runs to apoint, 

 thus making it triangular on cross section. 



5) The transverse ligament is a portion of the cotyloid ligament which 

 crossi - the notch at the lower portion of the acetabulum. The nutrient vessels 

 to the joint pass under this ligament. 



The synovial membrane of the hip-joint is reflected over the inner surface 

 of the capsular ligament on to the neck of the femur, and from here over to the 

 ligamentum teres to the bottom of the acetabulum. At this point it covers 

 some fat. As said before it frequently communicates with the bursa which is 

 under the Psoas muscle. 



The flexors of the hip-joint are all the muscles in the floor of Scarpa's tri- 

 angle, viz.. the Qiacus, Psoas magnus, Pectineus, Adductor brevis, Adductor 

 longus. The Sartorius, the R( ctus and the anterior fibers of the Gluteus niedius 

 and ( Uuteus minimus are also flexors of the hip-joint. 



The extensors of this joint are the Gluteus maximus, Biceps, Semimem- 

 branosus, and Sen itendinosus. 



'1 Ik adductors are the Addu< t< r 1< ngus, Adductor brevis, Adductor magnus 

 plus the Bic< ps, Gracilis, and lower part of the Gluteus maximus. 



Tin abductors of this joint are the Gluteus medius, and Gluteus minimus. 

 and the up] < r pan i f tin Glut< us maximus. 



Th< internal rotators an the anterior fibers of the Gluteus medius, Gluteus 

 minimus, and T< nsor fas< ia f< moris. 



Th( external rotators < f this joint are all the muscles in the gluteal region 

 excepl tin posterior fibers cf the Gluteus medius and Gluteus minimus, plus 

 tin lliacus, tin three Adductors, the Feetineus and the Sartorius. 



The tendino-trochanteric band is a str< ngthening band of the hip-joint. 



Thi ligamentum teres is an incorporated tendon of the P< ctineus muscle. 



Neiaton's line is a line drawn fr< m the anterior superior spineof the ilium 

 to tin tuberischii. 



Bryant's triangle is a triangle mad< by N< lat< n's line and a line drawn from 

 tin ant* i tor su] < i tor s] in< — of the ilium whi< h nn < ts a third line cor- 



responding to the long axis of the f< mur continued. 



Th( blood supply of the hip-joint is theinternal circumflex, gluteal, sciatic, 

 and ob 



Th< nerve supply is the anterior crural, the obturator, the obturator access- 

 ory, greal sciatic, and branches from the sacral plexus.
