152 Injuries of Bone. 



left tibia and fibula with the astragalus — macerated, showing 

 the above. 



The tibia has been severely comminuted and split, and 

 • several of the fragments are wanting. The fibula seems also to 

 have been broken about five inches from its lower end.

3. 307. Compound Comminuted Fracture of the Lower 

 End of the Tibia, involving* the Ankle-joint— Astragalus 



and lower half of a right tibia and fibula — muscles cleaned off — 

 in spirit, showing the above. 



The lower end of the upper fragment of the tibia is bare, and 

 some of the portions of the lower fragment have been removed, 

 so that the articular surface is no longer recognisable. The 

 fibula has been broken about four inches from the lower end, and 

 the fragments overlap. The upper surface of the astragalus 

 is almost completely denuded of cartilage. The soft parts which 

 remain round the ankle appear infiltrated with lymph. Severe 

 suppuration has evidently followed the injury. G. C. 1055. 

 Presented by Professor James Russell. 



3. 308. Badly united Fracture of the Lower End of the 

 Tibia into the Ankle-joint. — Right tibia, to which a small 



portion of the fibula adheres — macerated, showing the above. 



The union is very irregular, and a piece of the fibula has 

 become attached to the tibia at the seat of fracture. The rest 

 of the fibula is wanting. The main fracture has apparently 

 been from above downwards and forwards, but the lower 

 fragment has been comminuted into the ankle-joint. There 

 is a slight forward bend at the point of union. The upper 

 articular surface is set obliquely to the shaft, as in genu 

 varum, i.e. with the shaft of the tibia sloping downwards and 

 inwards. B. C. i. 1. M. 39.
