166 Injuries of Bone. 



protruded, and there has been periostitis ahove that, similar to 

 what was noted in No. 3. 342. Some erosions are present upon 

 the surface of the lower fragments. B. C. xvii. 33, 



3. 345. Severe Gunshot Fracture of the Lower End of the 



Femur. — The lower end of the shaft of a right femur — 

 macerated. Several pieces are missing, and the remaining 

 fragments are wired together. 



The wound was received at Waterloo. 



The condylar portion of the bone has been split in several 

 directions. The joint has been opened into, and, from the 

 erosion of the articular surface, must have been the seat of 

 suppuration. The lower end of the upper fragment shows 

 changes similar to those noted in No. 3. 342 and others.

3. 346. Gunshot Injury of the Inner Condyle of the Femur^ 



— Lower half of a right femur — macerated, to show the above. 



This wound was received at Corunna. Suppuration of the limb 

 followed the injury, and extended among the muscles of the calf. The- 

 patient was exhausted by hectic fever when amputation was performed. 



In Sir Charles Bell's drawing of this specimen ("Operative 

 Surgery," plate ii. fig. 1) the ball is seen lodged in the depression, 

 in front of the inner condyle. The walls of the cavity have 

 some necrotic fragments still adhering to them, but at other 

 places the bony lining has been somewhat condensed. The 

 outer shell of bone is splintered. B. C. xvii. 29. 



3. 347. Gunshot Injury of the Back of the Outer Condyle 



of the Femur. — Lower end of a left femur — macerated, to 

 illustrate the above. 



A musket ball had lodged in the back of the outer condyle at the 

 battle of Waterloo.
