Fractures of the Tibia and Fibula. 145 



of bone unites the tibia and fibula at the seat of fracture. 

 This form of mal-union is apt to occur if the heel be too much 

 supported during treatment. W. C. G. 5. 



3. 283. Badly united Fracture of both Bones near their 



Lower Ends. — Plaster cast of a right tibia and fibula, showing 

 the above. 



The fracture in the fibula was four inches from the lower 

 end, while in the tibia the fracture began about the same level, 

 and ran obliquely backwards and downwards. The lower 

 fragments were tilted backwards and inwards. A large amount 

 of callus had formed round the broken tibia. The cast is taken 

 from one in the Barclay Collection by James Kichardson. 



G. C. 3332. 



3. 284. United Fracture of both Bones near their Lower 



Ends. — Lower ends of a left tibia and fibula — macerated, show- 

 ing the above. 



The fracture has been oblique, and the break has occurred 

 a little higher in the tibia than in the fibula. The union has 

 been good, except that the tibia and fibula are united together 

 close to the ankle. B. C. i. 1. M. 41. 



3. 285. Ununited Comminuted Fracture of both Bones 



near the Lower End.— Lower third of a tibia— macerated, 



showing the above. The lower fragment of the fibula 



corresponding to that of the tibia adheres to it, but the upper 



part of the fibula is wanting. 



The upper fragment of the tibia has been split by the lower 



one, which has been driven into it. The broken surfaces are 



encrusted with newly formed bone round the fracture. The 



bones are eroded where they have been in contact, but have 



been mounted slightly separate to show the relationship. The 



fracture has probably been compound. G. C. 2780.
