Tiihercular Ostitis involving HijJ-joint. 465 



The whole bone is light and soft, and the channels for 

 blood-vessels are enlarged. The articular surface of the aceta- 

 bulum is rarefied and partially absorbed, and the interior of the 

 bone is filled with adipocere. G. C. 3642. 



7. 100. Tubercular Synovitis, involving- the Head of the 



Femur. — Vertical transverse section of the head and neck of a 

 left femur— macerated. 



The patient, a young man, had suffered from symptoms of hip- 

 joint disease for some time, and tlie head and the great trochanter were 

 excised. 



The articular surface is rarefied and rough all over. In 

 addition, the upper part of the head is greatly absorbed, pro- 

 bably from the disease there being aided by pressure.

7. 101. Tubercular Arthritis, with Destruction of the 



Head of the Femur. — Upper end of the right femur of a child 

 — in spirit, illustrating the above. 



The patient was a girl, aged four, who died in the Royal Hospital 

 for Sick Children, from disease of the hip-joint. 



The great and small trochanters were completely separated 

 from the shaft during life. The bone was therefore presumed 

 to be dislocated, from the amount of displacement which was 

 observed on moving the limb. The head has disappeared.
