178 Injuries of Bone. 



fragments, larger in front and on the sides, and smaller on the 

 back. There are only one or two fissures extending beyond 

 the comminuted portion, and these only for about one inch. 

 Probably the musket ball struck the femur obliquely, and passed 

 from the front upwards and outwards, carrying some of the 

 bone before it. G. C. 3423. 



Presented by Surgeon-General Billings, U.S.A. 



3. 380. Gunshot Fracture of the Femur, involving the 



Knee-joint. — Lower end of a right femur, severely injured. 



Just above the condyles on the back the cancellous tissue 

 is wanting, apparently having been transversely ploughed up 

 by the bullet. The bone is broken across a little above this 

 level, and a large piece has been driven out of the inner side. 

 The inner condyle has been detached. On the outer side, the 

 lower part of the aperture is somewhat circular, and its margins 

 are indented. The injury has evidently been caused by a 

 musket-ball striking the outer side about one inch above the 

 outer condyle. G. C. 3424.

3. 381. Gunshot Fracture of the Femur, involving- the 



Knee-joint. — Bones forming a left knee-joint — macerated, 

 showing the above. 



The bone has been irregularly ploughed up and broken 

 across, just above the articular surface. The outer shell of the 

 cancellous tissue has been split and turned aside at one place, 

 and the upper margin of the patella has been injured. 



G. C. 3425. 

 Presented by Surgeon-General Billings, U.S.A. 



3. 382. Bullet lodged in the Outer Condyle of the Femur. 



— Bones forming a right knee-joint — macerated, showing the 

 bullet in position.
