FIG. 465. ARTICULATIO COX,E, THE HIP-JOINT: ZONA ORBICULARIS (see p. 223), AND ITS 

 RELATIONS TO THE ILIOFEMORAL, PUBOFEMORAL, AND ISCHIOCAPSULAR LIGAMENTS ; THE 

 THIN PORTIONS OF THE CAPSULE, AND THE COMMUNICATION BETWEEN THE SYNOVIAL 

 CAVITY AND THE BURSA BENEATH THE TENDON OF THE ILIOPSOAS MUSCLE; THE 

 ACETABULUM, WITH THE TRANSVERSE LIGAMENT OF THE ACETABULUM, AND THE INTER- 

 ARTICULAR OR ROUND LIGAMENT. 



After the capsule of the right hip-joint had been prepared from without, the joint was fully flexed; the 

 capsule was then divided by a section in the direction of a line passing from the middle of the 

 upper border of the great trochanter to the inner border of the iliopectineal eminence ; the ilium 

 was cut away except for that portion of the bone which contributes to the formation of the 

 acetabulum, and the neck of the femur was sawn across just internal to the distal attachment of 

 the capsule ; the interarticular ligament was divided close to the head of the femur, and this 

 latter, together with the intracapsular portion of the neck, was removed ; the acetabulum and the 

 remaining proximal portion of the femur were divided in two by a continuation of the section 

 already made through the upper wall of the capsule ; the two halves of the acetabulum and the 

 head and neck of the femur were then opened out till the cut surfaces met at a very obtuse angle ; 

 so that the capsule and the cotyloid ligament were fully exposed from within. The synovial 

 membrane was dissected off, and the inner surface of the capsule cleaned from fat and cellular 

 tissue.
