198 Injuries of Joints. 



The tendons are not much displaced. The astragalus has pre- 

 served its relation to the tibia and fibula, but has been torn from 

 its attachments to the scaphoid and os calcis. The foot has 

 been twisted inwards, so as to leave the head of the astragalus 

 projecting on the outside. G. C. 1431.
