Fractures of the Tibia and Fibula. 147 



the Fibula higfheP up. — Right tibia and fibula — macerated, 

 showing the above. 



As in the previous specimen, the tibia has been broken at 

 the junction of the lower and middle thirds, and the fibula at 

 the junction of its two upper fourths. The broken ends of the 

 tibia are set at an angle, which projects slightly forwards. The 

 obliquity of the fracture of the tibia is the same as in the last 

 specimen. In the fibula the direction of the break is difficult 

 to trace, owing to irregularities at the seat of fracture. The 

 overlapping of the fragments is less than in the previous 

 specimen. B. C. i. 1. M. 34. 



3. 290. United Fracture of the Tibia near the Ankle-Joint, 

 and of the Fibula about the Middle.— Right tibia and 



fibula — macerated, showing the above. 



The line of fracture in the tibia is oblique from the outer 

 and posterior part of the bone downwards, inwards, and forwards. 

 In both bones the fragments overlap, and form an angle directed 

 slightly forwards. The fibula at the seat of fracture has, more- 

 over, been pressed towards the tibia. The grooves for tendons, 

 at the lower end of both bones, are increased in depth, probably 

 from chronic congestion. F. P. C. 178.

FRACTURES OF THE TIBIA. 



{Some of these have probably been indirect fractures of both bones, as the line of 

 obliquity corresponds to that seen in such specimens. ) 



3. 291. United Fracture of the Shaft about the Middle. 



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

 above. 



The bone was divided longitudinally, but the condition of 

 the interior is obscured by adipocere. 



The bone has evidently been comminuted, and the lower 

 fragment is rotated inwards. B. C. i. 1. M. 46. d.
