the anterior intertrochanteric line; the lower part is thinned 

 at its centre, so that the ligament may seem Y-shaped (Bige- 

 low) . Its outer part may be extended by an additional band 

 (ileo-trochanteric) which runs from the anterior part of the 

 dorsum of the acetabulum to the femoral neck, close to the 

 anterior end of the inner surface of the great trochanter. The 

 pubo-femoral (pubo-capsular) consist of bands arising from the 

 outer end of the pubic horizontal ramus, ilio-pectineal emi- 

 nence, and obturator crest and membrane. They are mostly 

 lost on the capsule but some pass to the lower part of the 

 neck of the femur and adjoin the lower attachment of the ilio- 

 femoral. The ischio-capsular is a broad short band attached 

 above to the ischium, between the small sciatic notch and ob- 

 turator foramen, and merged below with the zona orbicularis 

 of the capsule. [295] 



The interarticular ligament (ligamentum teres) lies within the 

 capsule; it is a somewhat flattened fibrous band running from 

 the upper half of the pit on the head of the femur to the lower 

 edge of the articular surface of the transverse ligament, with 

 extensions to the opposite borders of the acetabulum notch, 

 especially the posterior. The Haversian gland is a mass of fat 

 at the bottom of the acetabulum, which is covered by sy no vial 

 membrane and continuous with extra-capsular fat under the 

 transverse ligament. [295] 



The synovial membrane lines the capsule and passes, at its 

 acetabular end, onto the outer and then the inner surfaces of 

 the cotyloid and transverse ligaments, and over the Haversian 

 gland and ligamentum teres. Inferiorly it is reflected over the 

 femoral neck almost to the articular margin of the head, form- 

 ing loose folds over the retinacula near its line of reflection. 

 The bursa under the Ilio-psoas tendon may communicate with 

 the joint through an opening on the anterior wall of the capsule, 

 between the pubo-femoral and ilio-femoral ligaments. [295]
