3. 296. United Fracture of the Shaft near its Lower End. 



— Lower two-thirds of a left tibia — macerated, showing the 

 above. 



The line of fracture runs downwards and inwards. The 

 ends overlap, but the union is otherwise good, except that there 

 is an interval between the fragments at the back. Some marks 

 of chronic periostitis are seen near the fracture.

3. 297. United Fracture of the Shaft, which had an Ulcer 

 over it. — Lower three-fourths of a right tibia— macerated, 

 showing the above. 



The fragments are set at an angle, which projects slightly 

 forwards. At the seat of fracture, at the inner side, the surface 

 of the bone is opened out and rough, as if there had been an 

 ulcer over it. At other places the surface shows signs of 

 periostitis. B. C. i. 1. M. 40. a. 



S. 298. Ununited Fracture of the Shaft, a little below 



the Nutrient Foramen. —Portions of a right tibia and 

 fibula — macerated, showing the above. 



The fragment of the tibia has a conical lower end, and 

 is united externally to the fibula by a thick mass of new bone. 

 The lower fragment of the tibia is wanting. Note that the 

 fibula, below its union with the tibia, is thickened, as if taking 

 on the function of the missing fragment of the latter.
