3.312. Recent Severe Form of Pott's Fracture from a 



Crush. — Part of a right leg and foot, dissected to show the 

 relation of parts in the above — in spirit. 



The patient was a mason whose foot was severely crushed by a stone. 

 Gangrene set in, and a few days after the accident amputation of the 

 limb became necessary. 



There is a comminuted fracture of the fibula just above 

 the ankle. The inner malleolus has been broken off and 

 comminuted. The peroneal tendons are displaced forward. 

 Besides the above injuries, the posterior tibial artery was torn 

 across, and the soft parts were greatly bruised.

The fore part of the foot had been so severely crushed that amputa- 

 tion was necessary. 



The specimen illustrates the injuries usually met with in 

 Pott's fracture, the inner malleolus being broken off, and the 

 fibula fractured a few inches above its lower end. The 

 external lateral ligaments were divided by the surgeon, who

The patient, a man aged 44, slipped and twisted his foot under him. 

 When admitted to the Royal Iniirmary, Edinburgh, the lower part of the
