Tuhercular and Septic Disease. 291 



femur. There are, however, on the inner and posterior surfaces, 

 apertures and depressions, some of which lodge necrotic frag- 

 ments. The fibula shows new periosteal bone formation all 

 over. The outer surface of the patella is also very irregular, 

 from new bone formation. 



This has probably been a very chronic tubercular affection, 

 with numerous septic sinuses.

6. 234. Tubercular and Septic Disease of the Lower End of 



the Tibia. — Lower end of a left tibia and fibula — macerated, 

 illustrating the above. 



The leg was amputated for extensive disease of the ankle-joint. 



The lower half of the tibia shows some new periosteal bone 

 on the surface, with erosion and destruction in the interior. 

 The irregular erosions so often seen in tubercular disease are 

 especially noteworthy about four inches above the ankle. The 

 articular end seems to^have been necrotic, but is also very 

 irregular. The fibula has irregular new bone formation on 

 its surface. 



This has evidently been a tubercular case, complicated by 

 septic changes. B. C. 2. M. 39. 



6. 235. Tubercular and Septic Disease of Radius and 



Ulna. — Left radius and ulna — macerated, illustrating the 

 above. 



The crust of new bone on the shafts seems to be the result 

 of sepsis, but the irregular eating away of the crust, especially at 

 the lower end of the ulna, where the original bone is also partly 

 removed, has probably been due to tuberculosis.
