122 Injuries of Bone. 



3. 214. Comparatively Recent Oblique Fracture of the 



Shaft. — Section of the shaft of a femur — muscles dissected off — 

 dried, injected, and in turpentine, to illustrate the above. 

 Time was not afforded for union by bone. 



The specimen shows the vascularity of the material 

 covering the broken surfaces, and from which the new bone 

 would have been formed, B. C. i. 1. M. 44. 



3.215. Comparatively Recent Oblique Fracture of the 



Shaft. — Section of the lower end of a right femur — muscles 

 cleaned off, and in spirit, showing the above. 



The lower fragment over-rides in front of the upper, and 

 the ends overlap for about four inches. 



The interval between the broken ends of the bone is filled up 

 by soft, fibrous-looking material, which would have eventually 

 developed into bone. G. C. 2068.

3. 216. Comparatively Recent Comminuted Fracture of 



the Shaft. — Portion of the shaft of a femur — macerated, 

 showing the above. 



" The person lived some days after the accident, and at the time of 

 his death was a patient in the Middlesex Hospital, from the house- 

 surgeon of which, Mr Le Mann, I received the preparation. The fracture 

 seems to have proceeded nearly half through the bone from before, with- 

 out detaching but one large piece ; more backward several splinters have 

 broken off, many of which have united to a different part of the bone 

 than that which they were detaclied from. One part in particular shows 

 this, from the direction of the external fibres being ver}' oblique in the 

 splinter, and running directly from above downwards in the part of 

 the bone from which it was broken off. A piece of bone from three to four 

 inches in length on the back part of the femur, but not reaching the 

 anterior surface of it, has been broken off, and, without change of position, 

 has united in some places to the bone above, and had began to unite with 

 the bone below. Splinters of bone are found adhering even to the detached 

 portion. In some places there seems to have been no attempt at union.
