 of the ligament, which lies to the medial side, overlaps that

between the bones of the leg and the talus, and the weight of 

 the body is transferred through it to the foot. It is a joint 

 of great strength ; its stability being ensured not only by the 

 powerful ligaments which surround it, but also by the close 

 interlocking of the articulating surfaces. 



The bones which enter into the formation of the ankle 

 joint are the distal ends of the tibia and fibula and the 

 proximal, medial, and lateral surfaces of the talus. The distal 

 ends of the leg bones are very firmly united together by inter- 

 osseous and other ligaments which give the joint a certain 

 amount of elasticity or spring. They form a deep hollow
