Dissection. The capsule of the hip-joint should now be cleaned. 

 Cut through the iliacus and psoas below Poupart's ligament, and 

 turn them down. In doing so a large bursa will be opened which 

 facilitates the movement of these muscles over the front of the joint. 

 Sometimes it will be found that this bursa communicates with the 

 joint cavity through a thin part in the front of the capsule (fig. 63). 

 The rectus femoris, the sartorius, the tensor fasciae femoris, and 

 the glutens minimus should be cleared from the joint, and the 

 front, outer, and inner parts of the capsule cleaned, as has already 

 been done at the back. The intimate connection of the reflected

THE HIP-JOIXT. This articulation is a ball and socket joint, the Hip-joint, 

 head of the femur being received into the acetabulum of the hip- 

 bone. Connecting the bones are the following ligaments : one to jj 

 deepen the receiving cavity, which is named cotyloid ; another 

 between the articular surfaces of the bones the interarticular ; and 

 a capsule around all. 



In the capsule itself the student has to define a wide thick part Define its 

 in front, and a transverse band near the neck of the femur behind.
