connected with it by two powerful and important ligaments, 

 viz. a plantar and a lateral. 



The plantar calcaneo- navicular ligament (O.T. inferior 

 calcaneo-scaphoid ligament) is brought into view by the removal 

 of the talus. It fills up the angular gap between the 

 sustentaculum tali and the navicular bone, and enters 

 into the formation of the socket for the head of the talus
